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. 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.
