Description
| - The Virorco dumortierite-bearing pegmatites, in Sierra de San Luis, Argentina, are a group of thin, steeply dipping dikes one to 10 cm thick. The pegmatits are symmetrically zoned, with quartz, albite, oligoclase, tourmaline- and dumortierite-group minerals, muscovite and kyanite as the major phases; the accessory and trace minerals include beryl, chrysoberyl, garnet, fluorapatite, columbite-(Mn) to tantalite-(Mn), pollucite, gahnite, zircon, uraninite and thorite. Holmquistite was found in the exocontact assemblage. Primary textures of magmatic origin were partially disrupted by partial replacements by later minerals and incipient to strong deformation. Five textural and compositional types of tourmaline-supergroup minerals were identified in the different pegmatitic zones, ranging from dravite-rich compositions to rossmanite, passing through schorl and Mn-rich elbaite.
