چکیده انگلیسی
The Pöhrenk deposit was emplaced epigenetically after the host rocks and shares some characteristics with the paleokarst- and Mississippi-Valley-type deposits. Fluid inclusion and stable isotope data indicate that ore fluids for the mineralization were mildly hot (58 to 154 °C), highly saline (14 to 21 wt.% NaCl equivalent) formation waters and ore deposition occurred in a paleokarst environment. The driving force for fluid migration was both topographic gradients created by uplift and tectonic squeezing of basin sediments. The Paleocene granitoids in the north are considered as the potentially main source of F, Ba and Pb for the Pöhrenk deposit. Release of these elements from granitoids can be tied to erosion and leaching.
