Forum with Parliament Members : Students Against Sexual Orientation Discrimination ; Audio Recordings of the Proceedings Auteur(s) : Caribbean IRN Résumé : From the PNCR, GAP MPs free to vote conscience on gay rights bill
By Johann Earle
Stabroek News
June 11, 2003
The PNCR will allow its members to vote their conscience on the controversial Constitution (Amendment) Act of 2001 which seeks to prevent discrimination against persons on the basis of their sexual orientation and other grounds.
A number of religious organisations are opposed to the passage of the bill because it includes sexual orientation as one of the grounds. They are concerned that it could lead to a legalisation of homosexual relations and demands for recognition of gay marriages among other things.
PNCR Member of Parliament (MP) Vincent Alexander told a forum at the National Library on Saturday, that the Bill did not seek to legalise homosexuality, but to ensure that persons would not be discriminated against based on their sexual preferences.
He was one of two parliamentarians who showed up - the other being PNCR member, Myrna Peterkin.
The forum was organised by Students Against Sexual Orientation Discrimination (SASOD), a group comprising fifteen students from the University of Guyana which was formed about two weeks ago.
Alexander expects the vote on the bill to come up before the National Assembly in a matter of months.
Paul Hardy, Leader of the Guyana Action Party (GAP), told Stabroek News that his party would not be using the so-called parliamentary whip. He added that GAP took a decision that every member should vote according to his or her own conscience. “We have no right to deny the rights of others based on sexual orientation. [The Bill] will guarantee rights to the homosexual.” GAP is in Parliament as part of an alliance with the Working People’s Alliance. GAP/WPA has two MPs.
The bill was met with rejection from some members of the religious community in 2001 and as a result of this, the President did not assent to it.
In a statement on Monday, the Central Islamic Organisa-tion of Guyana (CIOG) said that it stood in firm opposition to the Bill. The CIOG says the general purpose of the bill may be commendable and that the organisation’s objection is not based on a willingness to promote discrimination. Rather, the CIOG said, it was based on the fact that specific legal protection on the basis of sexual orientation without definition or qualification gives tacit legitimacy to practices which are considered criminal in Islam. “It is foreseeable that such a legal nod of approval (subtle as it may be) of these practices may pave the way for greater social (or even legal) acceptability in the future which, from the perspective of all Muslims including those in Guyana, is an undesirable and sinful outcome,” the CIOG statement said.
At Saturday’s event, Muslim teacher Moulana Mohamed Ali Zenjibari spoke of instances of abuse, discrimination and harsh penalties meted out to gay and lesbian persons in countries such as Iran and Saudi Arabia and noted that the Quran did not sanction such punishments for homosexual behaviour.
President of the CIOG, Fazeel Ferouz told Stabroek News that a meeting to discuss a strategy with regards to the bill was planned for tomorrow with various religious groups.
Stabroek News tried to get a comment on the issue from the PPP/C but to no avail.
ROAR leader, Ravi Dev said that his party was now having discussions on the issue. ROAR feels that it is an important question which has to do with morality and should be discussed across the country. He added legislators had to be in tune with their constituents on the issue.
SASOD is lobbying for the legislation through the sensitisation of MPs.
Keimo Benjamin, a law student at UG, gave a presentation based on the jurisprudential aspects of the discussion on sexual orientation. He argued that morality should not be the only guiding principle on which to base the laws. Sexual activities between two consenting male adults in private could not be equated with a violation of a person’s rights, he said, making the point that the thrust of his presentation was not whether homosexuality was wrong, but whether it violated the rights of others. He said that the attitudes of some towards this subject were based on preconceived notions and prejudices. He cited studies to show that the suppression of certain perceived deviant sexual impulses in persons might do more harm than good. One Harvard University study of teens who said they were gay indicated that those teens were three times more likely to commit suicide.
Vidyaratha Kissoon, of Help and Shelter, in his contribution on Saturday, expressed his displeasure at the low turnout at the forum and urged the parliamentarians who showed up to take the message to their colleagues. He noted that because of homophobia, the numerical minority was terrified of speaking out against instances of discrimination. Gays and lesbians in Guyana were subjected to ridicule and abuse, and walk the streets at night not looking for sex necessarily, but for the companionship of persons who empathise with them.
During his presentation, Joel Simpson, another member of SASOD, outlined a number of changes made within national jurisdictions that had international implications. One such crucial change was South Africa’s 1996 adoption of a new constitution, making that country the first in the world to expressly include sexual orientation as a prohibited ground of discrimination. It was the first time a developing country had taken the lead with respect to the rights of sexual minorities.
He also said that according to Douglas Sanders, a Canadian jurist, the rights of homosexual, bisexual or transsexual men and women had never been officially recognised by the United Nations, despite the fact that international laws on the issue began to emerge at the close of the Second World War.
Simpson said that under Article 170 (5), as amended by Section 8 of the Constitution (Amendment) (No. 4) Act 2000, the President is required to assent to any bill which is returned by the National Assembly unaltered after a two-thirds majority within 90 days of its presentation to him. To the parliamentarians present, Simpson stressed that the onus was now on them to adequately represent their constituents which include lesbian, gay, bisexual and transsexual Guyanese.

Vote on sexual orientation should be a matter of conscience - MP Alexander
By Esther Elijah
Guyana Chronicle
June 8, 2003
PEOPLE’S National Congress (PNC/R) Member of Parliament Mr. Vincent Alexander, said the Opposition will vote on “conscience” when the piece of legislation on sexual orientation is again brought before the National Assembly.
“With specific reference to my party, when this Bill gets back to the Parliament in the spirit of the arguments here, we will not use the `whip’. Our party will not say we have to vote for the provision (in the Sexual Orientation Bill). We will allow our members to vote as a matter of conscience,” he told participants gathered in the Conference Room of the National Library.
“We feel this is a matter of conscience. You may end up with a collective position but you have to deal with us individually,” Alexander said at a poorly attended public consultation aimed at gaining support for sexual orientation to be considered a fundamental right in Guyana.
Alexander, one of the main persons who sat on the Constitutional Reform Commission that addressed this controversial clause, said the legislation was not meant to legalise homosexual activities in Guyana.
“It was intended to ensure that persons who have an orientation - a way of thinking - which may or may not lead to a certain activity, to not be discriminated against, in terms of their rights,” he explained.
Alexander noted that very often, discussions on the sexual orientation provision in the Bill have led to seepages into other areas where debates centre on the “right to be homosexual.”
“I am saying the Bill does not comment on that… However, law is peculiar, especially in a Common Law system. Once you venture out and change the law, very often you open other windows which we cannot definitively say exist or does not exist in advance,” he said.
“The fear of some people is that the legislators might say one thing and the Courts will eventually say something else. While some people can’t argue against the law, per say, they will say this has opened a window of opportunity not meant to be opened. So, it is better to stay without a window than open it and then have a possibility of something you didn’t intend to happen - happening sometime in the future.”
Alexander added: “I want to say I’ve found this activity to have been rich from the perspective of the amount of research which was done by student (speakers). Without any comment as to whether I agree with the arguments, I would wish that much more research on other issues be done by students, and that at the University (of Guyana) students would find it convenient to have forums on other issues, with the same depth of research for their own intellectual development.”
Alexander and other Opposition M.P, Lurlene Nestor were the only three Parliamentarians in attendance at the session organised by the recently formed `Students Against Sexual Orientation Discrimination’ (SASOD), a group that has a membership of 15 mostly University of Guyana (UG) students from various faculties.
SASOD was established two weeks ago.
With the exception of members of the press, the consultation only managed to attract 11 persons, a handful of who were SASOD members.
While congratulating the students for an “insightful” presentation, Nestor pointed out that whether or not she chooses to agree with their position is “another issue” and she is entitled to her “own view”.
“The issue of sexual orientation is very `toucheous’ …while we agree with the human rights provisions and all that as a society, we must also revert to our own society. Some of the very critical questions that I would want to ask is whether or not at the society (level) we are ready for that kind of thing,” she remarked.
“We cannot, at (any) time, ignore the religious groups in our society. If we look at statistics going back to 1992 from a survey done by the Bureau of Statistics, we would see that a small section of the Guyanese population might be considered as people who do not subscribe to a religious view. While the laws are not necessarily based on moral values, we must acknowledge the fact that we might want to revert to many of the cases that (concern) laws that protect public morality.”
Nestor told the speakers at the consultation these were some of the issues that they needed to deal with.
She highlighted, too, that what must be examined is the effects of same-sex marriages on society and how this issue must be tackled.
“These are some of the things we should consider and I don’t think you dealt with that in the presentations,” Nestor stated, adding that the issues must be addressed “frontally.”
“Do we think that with the coming to being of this Bill that there might be quite a number of challenges to the Constitution in relation to the same issue of a man marrying a man? What do we do at the society (level)? Do we recognise that?” were the questions directed at the five speakers at the session.
Nestor continued: “There is some argument that says, `Oh the Bill does not promote homosexuality or does not encourage a man to marry (another) man, but if you look at Section (15) that talks about `non-discrimination’ then how can we not, with the passage of this Bill, allow a man not to marry (another) man.”
According to Nestor, matters of this nature constitute some of the “inconsistencies” of the Bill.
On the argument raised by presenters at the session on who determines what is morality, Nestor said in the concept of democracy it is the people who are the determinants based on a “line of thinking.”
She also rebutted on grounds that put the spotlight on teachers who may have been caught “interfering” with their young students and who may subsequently be dismissed from their jobs.
“Could you imagine such a person interfering with a boy below age 10 - and by virtue of the fact that the Bill is there, the judges (in the case) will have to use their discretion in terms of what happens. We will have more Constitutional changes and problems (arising with the passage of the Bill).”
SASOD member and law student, Joel Simpson, in reply, said he doesn’t think any homosexual in Guyana wants to “run into a church and ask that people marry them or anything of that sort.”
At one point likening the church to a “club”, Simpson claimed the church has the right to exclude whomever it wants. He further stated that in accordance with the Constitution, people of the same sex do not currently have the right to marry, and will also not be able to do such an act with the passage of the Bill.
However, Simpson said it is possible that the law, with the passage of the Bill, would have to recognise same-sex domestic partnerships in relation to employment benefits, sharing of properties, etc.
Simpson said he believes there should be a realm of “public” and “private” morality between consenting adults, and implied that the Bill did not fully give “rights” to homosexuals.
But, Nestor interjected: “I am informing you further…that the Sexual Orientation provision has, in fact, in some way recognised the rights of homosexuals and we must accept that.”
Meanwhile, there was no vocal Christian representative(s) at the consultation and apart from the two Opposition representatives none other participant gave comments or directed questions at the presenters.
Other speakers in support of the sexual orientation clause were: Moulana Mohammed Ali Zenjiban, Assistant Director of the International Islamic College; Denuka Radzik from Red Thread, Keimo Benjamin, UG law student and Vidyartha Kissoon from Help & Shelter.
The Sunday Chronicle has been reliably informed that the Georgetown Ministers Fellowship, representing groups of Christian leaders staunchly against sexual orientation as a right in Guyana, have recently prepared a detailed 16-page document outlining issues arising from research to further boost their argument against the inclusion of the clause.
The document is yet to be made public.

Turismo intervención publica en Canarias: transición del modelo cuantitivo al cuaitativo Auteur(s) : Hernandez, Ramón Diaz Éditeur(s) : Université des Antilles Études caribéennes Résumé : El desbordamiento ocasionado por el modelo desarrollista de nuestra economía dio lugar a que el gobierno canario promoviera el Decreto (4/2001) para formular las Directrices de Ordenación General y del Turismo por entender que el territorio y los recursos naturales, en general, y la actividad turística, en particular, precisaban de una acción que articulase la orientación del desarrollo insular hacia un modelo sostenible. Se acompañó esa intervención con una serie de medidas cautelares tendentes a congelar el crecimiento y suspender el otorgamiento de licencias para la creación de nuevos establecimientos turísticos alojativos. Poco después, el ejecutivo canario emitió el Decreto 126/2001 para contener el crecimiento, y, finalmente, el Parlamento aprueba y pone en vigor la Ley de Medidas Urgentes en Materia de Ordenación del Territorio y del Turismo de Canarias (julio, 2001) para regular las condiciones que deben reunir los establecimientos de la modalidad hotelera con la máxima categoría. Por último, los diputados regionales dan el visto bueno a la Ley 19/2003 de Directrices de Ordenación General y las Directrices de Ordenación del Turismo de Canarias. Confronté à une surfréquentation touristique, le Gouvernement local des Îles Canaries a publié un Arrêt (4/2001) qui reformule les Orientations Générales du Territoire et du Tourisme. L’objectif est de s’entendre sur les bases d’un modèle de développement insulaire soutenable, en mettant l’accent sur la gestion des ressources naturelles en général et le tourisme plus particulièrement. Cet Arrêt a été accompagné de normes dont l’objectif est de limiter la construction de nouveaux bâtiments hôteliers. Peu après, le Gouvernement a publié l’Arrêt 126/2001 qui limitait le développement touristique. Le Parlement adopta un autre Arrêt, la «Ley de Medidas Urgentes en Materia de Ordenación del Territorio y del Turismo de Canarias » (juillet 2001) qui détermine les conditions exigées aux établissements hôteliers de plus haute catégorie. Le Parlement donne aussi son accord à l’Arrêt 19/2003, «Directrices de Ordenación General y Directrices de Ordenación del Turismo de Canarias ». Faced with excesses tourism, the local government of the Canary Islands issued a judgement (4 / 2001), which reformulates General Guidelines of Territory and Tourism. The aim is to set up the basis of a model of sustainable island development, with emphasis on natural resource management in general and tourism in particular. This decision was accompanied by standards whose objective is to limit the construction of new buildings for hotels. Shortly thereafter, the Government issued the ruling 126/2001 which limited the development of tourism. Parliament adopted another decree, "Ley de Medidas Urgent en Materia de Ordenación del Territorio y del Turismo de Canarias" (July 2001) which determines the conditions required for hotels higher category. The Parliament also gives its agreement to stop 19/2003, "Directrices de Ordenación General y Directrices de Ordenación del Turismo de Canarias."

A Warehouse filled with cigar boxes at Gradiaz-Annis and Co. Auteur(s) : Robertson and Fresh Photographers, 1925-1960 ( Photographer ) Résumé : Julius B. Annis was born June 4, 1890 in Luvno, Hungary. At present there is nothing known of his parentage, or when he emigrated to the United States. It is known that he registered for the draft during World War One and at that time he was residing at Brooklyn, New York. He married Minnie Brosow before 1917 and had at least one child, Morton Lawrence Annis Sr.
It is evident that Julius became affiliated with one of the larger and well known cigar companies, "Sanchez and Haya" in New York City. A brief history of this cigar company and it's founders is in order, so that the evolution of the company can be seen in regards to "J. B. Annis".
"Fact & Fancy About Cigars and Tobacco", by Morton L. Annis Sr. (1967)
In 1867, Senors Ignacio Haya and Serfino Sanchez, natives of Spain came to New York City with $1000.00 in capital and started what was to become one of the most successful cigar manufacturies in the world. In 1886 they moved their operations to Tampa, Florida and they received the U.S. Revenue designation of "Factory No. 1". Tampa soon became the cigar manufacturing industry giant and Sanchez & Haya retained it's leadership roll. The company ultimately acquired and merged with many of the old-line Tampa producers, such as Morgan Cigar Co., Schwab-Davis y Cia. and many more. By 1892, both Senor Haya and Sanchez were leaders of the Spanish community and their financial ability, philanthropy, and industry were legendary.
J. B. (Bunny) Annis began as a "drummer", or cigar salesman, who traveled from coast to coast selling his wares to Tobacconist and cigar merchants. "Dapper, loquacious, true bon vivants of the era .. perhaps the original American Salesman." Julius Annis, was at this time a guiding spirit and became partners in what is now known as Gradiaz, Annis or "Gradiaz y Annis", and was the Dean of these legendary "Knights of the Panetela."
In 1963 Gradiaz Annis became a Division of General Cigar Co., Inc. Julius Benjamin Annis died the following year (June 1964) in Tampa. His son, Morton Lawrence Annis Sr. (1917-1979), President of Gradiaz, Annis, wrote about his father in 1967:
"My father had a basic compelling motivation for excellence of product which was, in truth, his religion and his way of life. His love for tobacco and fine cigars was sacrosanct and so traditional in concept that he vigorously opposed all modern technological advances, preferring to create cigars in the great classic style of his youth."
Gradiaz, Annis is still known world wide as "World Leader in Luxury Cigars". (Funding) Funded in part by the Institute for Museum and Library Services (IMLS), Ephemeral Cities Project.

An eddy-permitting model of the Atlantic circulation: Evaluating open boundary conditions Auteur(s) : Treguier, Anne-marie Barnier, B De Miranda, A Molines, J Grima, N Imbard, M Madec, G Messager, Christophe Éditeur(s) : American Geophysical Union Résumé : As part of the French CLIPPER project, an eddy permitting model of the Atlantic circulation has been run for 22 years. The domain has open boundaries at Drake passage and at 30 degreesE, from Africa to Antarctica. The simulated mean circulation, as well as the eddy activity, is satisfactory for a 1/3 degrees model resolution, and the meridional heat transport at 30 degreesS is within the range estimated from observations. We use the "mixed" open boundary algorithm of Barnier et al. [1998], which has both a radiation condition and a relaxation to climatology. The climatological boundary forcing strongly constrains the solution in the whole domain. The model heat balance adjusts through the surface (heat flux retroaction term) more than the open boundaries. The radiation phase velocities calculated within the algorithm are analyzed. This shows, quite surprisingly, that both the eastern and western boundaries have a similar behavior, regardless of the preferred directions for advection (mainly eastward) and wave propagation (mainly westward). Our results confirm that open boundary algorithms behave differently according to the dynamics of the region considered. The passive boundary condition that Penduff et al. [2000] applied successfully in the north eastern Atlantic does not work in the present South Atlantic model. We emphasize the need for a careful prescription of the climatology at the open boundary, for which a new approach based on synoptic sections is implemented.

Root zone of the sheeted dike complex in the Oman ophiolite Auteur(s) : Nicolas, Adolphe Boudier, Françoise Koepke, J. France, Lyderic Ildefonse, Benoit Mevel, C. Auteurs secondaires : Géosciences Montpellier ; Université des Antilles et de la Guyane (UAG) - Institut national des sciences de l'Univers (INSU - CNRS) - Université de Montpellier (UM) - Centre National de la Recherche Scientifique (CNRS) Institut für Mineralogie, Leibniz Universität Hannover ; Université du Québec Laboratoire de Géosciences Marines (LGM) ; Université Pierre et Marie Curie - Paris 6 (UPMC) - IPG PARIS - Université Paris Diderot - Paris 7 (UPD7) - Centre National de la Recherche Scientifique (CNRS) Éditeur(s) : HAL CCSD AGU and the Geochemical Society Résumé : International audience In the Oman ophiolite crustal section, a contact zone between the gabbro unit and the volcanics and diabase sheeted dikes, called the root zone of the sheeted dike complex, has been recently mapped at a fine scale in a selected area. The Oman ophiolite is derived from a fast spreading ridge which had a melt lens located between the main gabbro unit and the root zone of the sheeted dike complex. With a few exceptions accounted for, this horizon has a fairly constant thickness, similar to 100 m, and a crude internal pseudo-stratigraphy. At the base of the root zone are isotropic ophitic gabbros interpreted as a thermal boundary layer. This layer is transitional between the magmatic system of the melt lens, convecting at 1200 degrees C, and a high-temperature (< 1100 degrees C) hydrothermal system, convecting within the root zone. Above this level, the isotropic gabbros have been, locally, largely molten due to an influx of seawater, at similar to 1100 degrees C, thus generating varitextured ophitic and pegmatitic gabbros. These latter gabbros constitute the upper part of the root zone and are associated with trondjhemitic intrusions as screens in the lower sheeted dikes. Diorites and trondjhemites were also generated by hydrous melting, at temperatures below 1000 degrees C. The whole root zone is a domain of very sharp average thermal gradient (similar to 7 degrees C/m). At the top of the root zone, a new thermal boundary layer, with diabase dikes hydrated in amphibolite facies conditions, separates the preceding high- temperature convective system from the well-known greenschist facies (< 450 degrees C) hydrothermal system operating throughout the sheeted dike complex, up to the seafloor. The isotropic gabbros near the base of the root zone are intruded by protodikes with distinctive microgranular margins and an ophitic center. Protodike swarms are exceptional because, intruding a medium at similar to 1100 degrees C, they are largely destroyed by dike-in-dike intrusions and by hydrous melting. However, they demonstrate that this zone was generated by melt conduits issued from the underlying melt lens. Each dike of the sheeted dike complex is thus fed by one protodike. As this zone has been recently drilled by IODP in the eastern Pacific Ocean, a brief comparison is proposed.

Molecular Phylogeny of the Astrophorida (Porifera, Demospongiae(rho)) Reveals an Unexpected High Level of Spicule Homoplasy Auteur(s) : Cardenas, Paco Xavier, Joana R. Reveillaud, Julie Schander, Christoffer Rapp, Hans Tore Éditeur(s) : Public Library Science Résumé : Background: The Astrophorida (Porifera, Demospongiae(rho)) is geographically and bathymetrically widely distributed. Systema Porifera currently includes five families in this order: Ancorinidae, Calthropellidae, Geodiidae, Pachastrellidae and Thrombidae. To date, molecular phylogenetic studies including Astrophorida species are scarce and offer limited sampling. Phylogenetic relationships within this order are therefore for the most part unknown and hypotheses based on morphology largely untested. Astrophorida taxa have very diverse spicule sets that make them a model of choice to investigate spicule evolution. Methodology/Principal Findings: With a sampling of 153 specimens (9 families, 29 genera, 89 species) covering the deep- and shallow-waters worldwide, this work presents the first comprehensive molecular phylogeny of the Astrophorida, using a cytochrome c oxidase subunit I (COI) gene partial sequence and the 59 end terminal part of the 28S rDNA gene (C1-D2 domains). The resulting tree suggested that i) the Astrophorida included some lithistid families and some Alectonidae species, ii) the sub-orders Euastrophorida and Streptosclerophorida were both polyphyletic, iii) the Geodiidae, the Ancorinidae and the Pachastrellidae were not monophyletic, iv) the Calthropellidae was part of the Geodiidae clade (Calthropella at least), and finally that v) many genera were polyphyletic (Ecionemia, Erylus, Poecillastra, Penares, Rhabdastrella, Stelletta and Vulcanella). Conclusion: The Astrophorida is a larger order than previously considered, comprising ca. 820 species. Based on these results, we propose new classifications for the Astrophorida using both the classical rank-based nomenclature (i.e., Linnaean classification) and the phylogenetic nomenclature following the PhyloCode, independent of taxonomic rank. A key to the Astrophorida families, sub-families and genera incertae sedis is also included. Incongruences between our molecular tree and the current classification can be explained by the banality of convergent evolution and secondary loss in spicule evolution. These processes have taken place many times, in all the major clades, for megascleres and microscleres.

Earth's Continental Lithosphere Through Time Auteur(s) : Hawkesworth, Chris j. Cawood, Peter a. Dhuime, Bruno Kemp, Tony i. s. Auteurs secondaires : University of Bristol University of St. Andrews Géosciences Montpellier ; Université des Antilles et de la Guyane (UAG) - Institut national des sciences de l'Univers (INSU - CNRS) - Université de Montpellier (UM) - Centre National de la Recherche Scientifique (CNRS) University of Western Australia, Perth Éditeur(s) : HAL CCSD Annual Reviews Résumé : International audience The record of the continental lithosphere is patchy and incomplete; no known rock is older than 4.02 Ga, and less than 5% of the rocks preserved are older than 3 Ga. In addition, there is no recognizable mantle lithosphere from before 3 Ga. We infer that there was lithosphere before 3 Ga and that ∼3 Ga marks the stabilization of blocks of continental lithosphere that have since survived. This was linked to plate tectonics emerging as the dominant tectonic regime in response to thermal cooling, the development of a more rigid lithosphere, and the recycling of water, which may in turn have facilitated plate tectonics. A number of models, using different approaches, suggest that at 3 Ga the volume of continental crust was ∼70% of its present-day volume and that this may be a minimum value. The continental crust before 3 Ga was on average more mafic than that generated subsequently, and this pre-3 Ga mafic new crust had fractionated Lu/Hf and Sm/Nd ratios as inferred for the sources of tonalite-trondhjemite-granodiorite and later granites. The more intermediate composition of new crust generated since 3 Ga is indicated by its higher Rb/Sr ratios. This change in composition was associated with an increase in crustal thickness, which resulted in more emergent crust available for weathering and erosion. This in turn led to an increase in the Sr isotope ratios of seawater and in the drawdown of CO2. Since 3 Ga, the preserved record of the continental crust is marked by global cycles of peaks and troughs of U-Pb crystallization ages, with the peaks of ages appearing to match periods of supercontinent assembly. There is increasing evidence that the peaks of ages represent enhanced preservation of magmatic rocks in periods leading up to and including continental collision in the assembly of supercontinents. These are times of increased crustal growth because more of the crust that is generated is retained within the crust. The rates of generation of continental crust and mantle lithosphere may have remained relatively constant at least since 3 Ga, yet the rates of destruction of continental crust have changed with time. Only relatively small volumes of rock are preserved from before 3 Ga, and so it remains difficult to establish which of these are representative of global processes and the extent to which the rock record before 3 Ga is distorted by particular biases.

Continental growth seen through the sedimentary record Auteur(s) : Dhuime, Bruno Hawkesworth, Chris j. Delavault, Helene Cawood, Peter a. Auteurs secondaires : Géosciences Montpellier ; Université des Antilles et de la Guyane (UAG) - Institut national des sciences de l'Univers (INSU - CNRS) - Université de Montpellier (UM) - Centre National de la Recherche Scientifique (CNRS) University of Bristol University of St. Andrews Éditeur(s) : HAL CCSD Elsevier Résumé : International audience Sedimentary rocks and detrital minerals sample large areas of the continental crust, and they are increasingly seen as a reliable archive for its global evolution. This study presents two approaches to model the growth of the continental crust through the sedimentary archive. The first builds on the variations in U-Pb, Hf and O isotopes in global databases of detrital zircons. We show that uncertainty in the Hf isotope composition of the mantle reservoir from which new crust separated, in the 176Lu/177Hf ratio of that new crust, and in the contribution in the databases of zircons that experienced ancient Pb loss(es), adds some uncertainty to the individual Hf model ages, but not to the overall shape of the calculated continental growth curves. The second approach is based on the variation of Nd isotopes in 645 worldwide fine-grained continental sedimentary rocks with different deposition ages, which requires a correction of the bias induced by preferential erosion of younger rocks through an erosion parameter referred to as K. This dimensionless parameter relates the proportions of younger to older source rocks in the sediment, to the proportions of younger to older source rocks present in the crust from which the sediment was derived. We suggest that a Hadean/Archaean value of K = 1 (i.e., no preferential erosion), and that post-Archaean values of K = 4–6, may be reasonable for the global Earth system. Models built on the detrital zircon and the fine-grained sediment records independently suggest that at least 65% of the present volume of continental crust was established by 3 Ga. The continental crust has been generated continuously, but with a marked decrease in the growth rate at ~ 3 Ga. The period from > 4 Ga to ~ 3 Ga is characterised by relatively high net rates of continental growth (2.9–3.4 km3 yr− 1 on average), which are similar to the rates at which new crust is generated (and destroyed) at the present time. Net growth rates are much lower since 3 Ga (0.6–0.9 km3 yr− 1 on average), which can be attributed to higher rates of destruction of continental crust. The change in slope in the continental growth curve at ~ 3 Ga is taken to indicate a global change in the way bulk crust was generated and preserved, and this change has been linked to the onset of subduction-driven plate tectonics. At least 100% of the present volume of the continental crust has been destroyed and recycled back into the mantle since ~ 3 Ga, and this time marks a transition in the average composition of new continental crust. Continental crust generated before 3 Ga was on average mafic, dense, relatively thin (< 20 km) and therefore different from the calc-alkaline andesitic crust that dominates the continental record today. Continental crust that formed after 3 Ga gradually became more intermediate in composition, buoyant and thicker. The increase in crustal thickness is accompanied by increasing rates of crustal reworking and increasing input of sediment to the ocean. These changes may have been accommodated by a change in lithospheric strength at around 3 Ga, as it became strong enough to support high-relief crust. This time period therefore indicates when significant volumes of continental crust started to become emergent and were available for erosion and weathering, thus impacting on the composition of the atmosphere and the oceans.
