Résumé : Le présent article introduit les contributions du numéro de la revue Etudes Caribéennes consacré à la thématique de la mondialisation. L’article passe en revue les différentes théories de la mondialisation, en particulier le courant hyper-globaliste, le courant sceptique et le courant transformationiste. En analysant les différentes contributions du numéro, l’auteur conclut que la majorité des articles se range du côté du transformationisme.
The present article introduces the articles of the issue of the journal Etudes Caribéennes, the theme of which is globalization. The introductory article reviews the theoretical literature on the concept of globalization, particularly the perspectives of the hyper-globalists, the skeptics, and the transformationalists. Analysis of the various articles leads the author to conclude that the majority of them side with transformationalism.

Résumé : Serpentinisation of mantle rocks, leading to natural venting of hydrogen and methane, has been reported to occur at the global scale, wherever fluids percolate in ultramafic formations. Here we compare gas composition from two on-land, low-temperature, and hyper-alkaline springs hosted on ultramafic rocks in the ophiolite massifs of the Sultanate of Oman and the Ligurian Alps (Voltri Group, Genoa region, Northern Italy). These two settings exhibit similar chemical and mineralogical features but show diverse styles of gas venting. Commonly to all hyper-alkaline springs, gases are characterised by relatively high N-2, very low O-2 and CO2 concentrations, and a strong enrichment in H-2 and CH4. The comparison between Oman and Liguria highlights a high variability of the H-2/CH4 ratios whereby the gas phase of the Oman Ophiolite is enriched in H-2 whereas being CH4 enriched in the Voltri Ophiolite. These results combined with literature data define three groups that may reflect different stages of serpentinisation producing fluids from hydrogen-dominated to methane-dominated. The origin of these distinct groups might lie in the difference of the mineralogical composition of the rocks within which the fluids circulate, on the degree of alteration of the rocks and finally on the geological/metamorphic history of the ophiolite.

Résumé : Cet éditorial présente les objectifs du numéro 22 d’Etudes Caribéennes et résume les courants conceptuels autour du phénomène de mondialisation. Ces derniers oscillent entre les interprétations extrêmes de l’hyper-globalisme, et celles plus modérées des sceptiques et des transformationistes. En convoquant la pensée d’Edouard Glissant, l’auteur conclut que les articles se situent conceptuellement entre le scepticisme et le transformationisme.
This editorial summarizes the goals of the issue, number 22, of Etudes Caribéennes and the various conceptual perspectives around the phenomenon called “globalization”. The latter range from hyperglobalism’s extreme views to skepticism’s and transformationalism’s more moderate approaches. Drawing upon Edouard Glissant’s thought, the author concludes that the articles of this issue position themselves conceptually between skepticism and transformationalism.
