Mineralogy and origin of supergene mineralization at the Farbiště ore occurrence near Poniky, central Slovakia
Original language description
Supergene mineralization at the hydrothermal Farbište ore occurrence near Poniky, central Slovakia, was studied using optical and electron scanning microscopy, X-ray powder diffraction, electron microprobe and IR spectroscopy. Two principal associationsof the supergene minerals were observed. The first is represented mostly by tyrolite with a higher content of sulphate groups and chrysocolla associated with copper carbonates. The second is characterized by a rich assemblage of copper arsenates: low-S tyrolite, strashimirite, parnauite, olivenite, cornwallite, cornubite, euchroite and clinoclase, which occur together with chrysocolla, bariopharmacosiderite-Q, brochantite, azurite and malachite. Both associations formed as a result of decomposition of primary ore minerals, especially tennantite, which is the prevalent primary ore mineral at the Farbište occurrence and was the main source of Cu, As and S ions in the supergene zone.
