Crystal chemistry of feldspar and muscovite from pegmatites of villa praga-las lagunas group, Conlara district, San Luis. relations with Nb-Ta/Sn-Li mineralizations

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 peg...
