Summary:In the Palaeozoic sediments and metarhyolites of the Gornji Vakuf area, 47 ore deposits were investigated by various geological and geochemical methods. The types of ore deposit distinguished were: 1) alluvial, diluvial and fluvio-glacial placers, 2) epigenetic baryte-siderite-tetrahedrite veins in the Silurian-Devonian schist complex and Upper Permian almost mineralic baryte (± tetrahedrite) veins, breccias and orebodies in the Middle Devonian carbonate complex and 3) post-kinematic monomineralic metamorphogenic quartz deposits interlayering the schists. The hydrothermal deposits occur exclusively in Palaeozoic strata and have a simple monotonous paragenesis of baryte ± siderite with Hg-tetrahedrite; the siderites are characterized by high CaO and MgO, and low MnO, while the tetrahedrites are Hg-, Ag-, Au-, Bi-bearing, and the baryte has an average content of 2.9 wt.% SrSO4. A stable isotope study showed Δ34S +150/00 in baryte, -10.10/00 in siderite, with Δ18O -9.60/00 and Δ13C -3.70/00 in siderite. Microthermometry gave Th in baryte as 200°C. These data are similar to those obtained for minerals of the Kresevo area and thus the authors assign the Gornji Vakuf deposits also to the post-Variscan tectonic event. [R.A.H.]
