The Krasna Hora Epizonal Orogenic Sb-Au Deposit, Bohemian Massif, Czech Republic

Abstract

The Krasna Hora Sb-Au deposit represents Variscan epizonal type of orogenic gold deposit unique to Bohemian Massif due to significant abundance of Sb-bearing phases. Fluid inclusion data suggest formation of early gold at 310 to 240 degrees C. and late stibnite and associated gold under conditions of 230 to 120 degrees C, shallow depth (approximate to 2km) and mixing of crustal and meteoric fluids.
