Metamorphosed gold deposit from Orlik near Humpolec, Czech Republic
Original language description
The paper presents mineralogic considerations about gold ores in the Orlik deposit (Czech Republic). Data have been obtained on samples coming from medieval pit. Studies of sulfidic ores revealed typical pyrrhotite-löllingite-arsenopyrite and gold textures. These aggregates were recently linked to certain conditions of LP/MP-HT metamorphic evolution. Documented textures confirm the premetamorphic origin of gold-bearing ores and serious remobilisation of gold. The conditions of older (~329 Ma) migmatitemetamorphism with temperatures up to 730 oC and pressure about 6 kbar were sufficient to decompose premetamorphic gold bearing arsenopyrite and form löllingite-pyrrhotite assemblages with the younger generation of arsenopyrite and gold. Also significantremobilisation of gold and sulfides into wall rock was observed.
