Resum
The Angel pegmatite forms part of the Comechingones pegmatitic field, in central Argentina, which is made up of pegmatites characterized by low to intermediate degrees of fractionation, classified as beryl-columbite-phosphate subtype pegmatites. These pegmatites are syntectonic with a regional shear zone. The Angel pegmatite contains associations with quartz, microcline, plagioclase, a first generation of muscovite (Muscovite I), beryl, members of the columbite group, triplite, and montebrasite....
