Título:
THE DUMORTIERITE-BEARING ASSEMBLAGES OF VIRORCO, SAN LUIS, ARGENTINA: ARE THEY PEGMATITIC DIKES OR HYDROTHERMAL VEINS?

Resumen:
The descriptive mineralogy of dumortieritebearing assemblages of Virorco was initially recorded by Gay & Galliski (1978). These rocks consist of zoned veins with dumortierite-tourmaline-kyanitechrysoberyl, now regarded as an assemblage found in granitic pegmatites of the abyssal class (Černý & Ercit 2005). The mineralogy and geochemistry of these rocks were studied in more detail, including EPM and LA-ICPMS chemical analyses of minerals, and conventional chemical analyses of rocks, in order to clarify the origin and parameters of crystallization.
