Résumé
This dataset comprises geochemical analyses from the Evisa peralkaline rare-metal granite (Corsica, France). A comprehensive analysis of the whole rock and specific mineral species was conducted using multiple analytical methods, including ICP-AES, ICP-MS, EPMA, and LA-ICP-MS. The initial objective of this study was to explore the conditions of crystallization and subsequent alteration of amphibole-bearing rare earth granites, which contain significant concentrations of REE (rare earth elements), especially the heavier ones (HREE). At Evisa, the distribution of REE within the various rock types was found to be heterogeneous, as evidenced by Whole Rock Analyses, and incorporated into a variety of exotic minerals, the latter being the subject of several types of in-situ analyses. Furthermore, the numerous generations of hydrothermal alterations highlight the successive remobilization of REE.
