Magmatic vs. hydrothermal origin of fluorites from Vlastejovice, Bohemian Massif
|
Several aspects of fluorite mineralization in barren pegmatites are studied and discussed in order to explain their magmatic or hydrothermal origin. The barren pegmatites are intruded in skarns at Vlastejovice in the northern part of the Moldanubian Zone. Abundant violet to colourless fluorite with hornblende and garnet were formed during pegmatite contamination by the country-rock skarn. The process included import of calcium and fluorine from the skarn body and formation of reaction zones along the pegmatite margins. Optical microscopy and cathodoluminiscence study show that fluorites are ...
