Abstract:

West of Tilisarao, in San Luis province, Argentine, there is a group of pegmatites of LCT signature belonging to the Villa Praga-Las Lagunas Group, a part of the Conlara Pegmatitic District of the Sierra de San Luis. This group intrudes schist and gneiss of the Conlara Metamorphic Complex. These pegmatites belong to the Muscovite to Muscovite-Rare Elements (MS-REL) class, MSREL-Li subclass and Rare Elements, REL-Li subclass, Beryl and Complex type. Chemical analyses of major and trace elements of feldspars and muscovites were carried out to infer the evolution of the pegmatitic bodies throughout the analyses of the composition and possible substitutions occurred inside each crystal. Comparison of our results with those from other pegmatites of the Conlara District as well as with pegmatites of the Pringles Metamorphic Complex and global examples indicates that the La Ribereña pegmatite could potentially carry Nb-Ta mineralization. © 2017, Asociacion Geologica Argentina.
