Rude, Samobor deposit as a prototype of the siderite -barite -polysulfide -hematite mineralization in the Inner Dinarides, Croatia
Rude, Samoborska gora ore deposit is a subterrestrial, hydrothern1al siderite-hematite- polysulfide-barite mineralization, with well developed SEDEX part of the deposit. It is Permo- Triassic in age, situated in the westernmost part of the Zagorje-Mid- Transdanubian zone (ZMT), at the margins of the Dinaridic carbonate platfonn. The deposits of similar genetic style, like Rude-Samobor, Bistra-Medvednica, Rudabanya (Hungary), accommodate along the Zagorje-Mid- Transdanubian zone (ZMT), a northwestern extension of the Internal Dinarides. The zone stretches SW-NE, and terminates within Gemerides with Rudnyani, Roznava, and other siderite-polysulfide-barite deposits in Slovakia. Fluid inclusion PVTX characteristics, Pb-isotope and sulfur isotope data provide sufficient information which reveals their geotectonic and genetic heritage. Uniformity of δ 34S values of vein barite, around 10‰ , suggests the engagement of Pennian seawater in the hydrothern1al ore-fonning processes. Molar ratios of Na/Br and Cl/Br, following the evaporation trend, confirm the propossed model of the engagement of Permian seawater, modified by evaporation and fractionation of halite, in the ore-forming process. The results may be applied in other siderite-hematite-polysulfide deposits within the Dinarides, Gemerides and possibly Eastern Alps.
