The Variscan Kasperske Hory orogenic gold deposit, Bohemian Massif, Czech Republic

Popis výsledku v původním jazyce

Kasperske Hory, one of the largest gold deposits in the Bohemian Massif, is characterised by shear zone-related gold-bearing quartz veins at the tectonic boundary of the two metamorphic terranes of the Moldanubian Unit. Studies of the geology, mineral paragenesis, fluid inclusions and oxygen geothermometry have been carried out to determine the mineralisation events and alternative P-T-t model of this deposit. The pre-mineralisation stage is characterised by geochemical evidence of pegmatites (similar to 700 C and 1.1-0.45 GPa) and metamorphic structures resulting from deformation Dx+1 at the regional metamorphic peak (650 degrees C and 0.5 GPa). The mineralisation in Dx+2 began to develop from the formation of the Q(1) and Q(2) quartz veins (Stage I)under brittle-ductile conditions with the N-S extension; these quartz veins were filled mainly by apatite, plagioclase-1, muscovite and arsenopyrite-1. Revised and reinterpreted gechronological data indicate that the earliest quartz veins
