Résumé : International audience
The Madeira Sn-Nb-Ta deposit corresponds to the albite-enriched facies of Madeira granite (Madeira Suite) that is part of a NE-SW alignment of three granitic bodies. Structural analyses suggest that the albite-enriched granite emplacement and development of related structures occurred in a different tectonic setting than earlier facies of the granitic bodies in the NE-SW alignment and that the structure was dominated by a N-NE-trending shortening related to a left-lateral motion along a NE-SW corridor within a Riedel shear. Three types of structures (flat-lying, near vertical fractures, and geodes/miaroles) concentrated the last magmatic-related fluid in the albite-enriched granite. U-Pb in situ zircon dating of the albite-enriched granite yielded an age of 1,822 ± 22 Ma. The other granitic plutons of the Madeira Suite, Água Boa granite (topaz-granite facies), and Europa per-alkaline granite formed at 1,825 ± 14 Ma, 1,831± 11 Ma, and 1,839 ± 10 Ma, respectively. The granite bodies of the Madeira Suite occur in an area occupied by a cauldron complex composed of volcanic sequences (Iricoumé Group) and associated A-type granites (Mapuera Suite), and their formation was controlled by the reactivation of the cauldron structures and the pre-existing structures. The gap between the cauldron complex and the Madeira Suite is no greater than 35 Ma. The geological evolution was reanalyzed from the perspective of an entire extensional environment where three successive episodes of A-type magmatism and basin formation (Urupi Formation) occurred. The data and interpretations of this work imply crucial constraints on the petrologic models proposed for the albite-enriched granite and, consequently, on the genesis of the Madeira deposit

Résumé : International audience
The Madeira deposit (Sn, Nb, Ta) at Pitinga, Amazonia, in Brazil, is associated with the albite-enriched facies of the A-type Madeira granite (~1,820 Ma). Fluorine (cryolite), Y, REE, Li, Zr, and Th are potential by-products of the disseminated ore. We studied the xenotime from the core albite-enriched (CAG), transitional albite-enriched granite (TAG) and pegmatitic albite-enriched granite (PAG). In all these rocks, xenotime is magmatic, has high HREE contents (0.37 to 0.54 atoms per formula unit; LREE are not detected), and low U, Th and Ca content. The CAG xenotime is the richest in REE, followed by that in the PAG and TAG units. Fluorine was detected in all xenotime crystals from CAG (up to 5.10%) and from PAG (up to 1.40%) and in most crystals from TAG (up to 0.68%). Where the xenotime is richer in F, the Na and Si increase, the P, Ca, and the effectiveness of a thorite-type substitution decrease. Fluorine controls the ratio REE/Y; the richer the xenotime in F, the richer it is in REE, in particular Er and Yb. The cell parameters a and c are significantly shortened in F-rich xenotime. There is no evidence of OH in the structure. We contend that fluorine substitutes for O to form PO3F tetrahedra, as in bobdownsite. The formation of the PO3F tetrahedra in the xenotime accounts well for the compatibility between the crystallographic characteristics and the chemical composition.
