Origin of the Zálesí U - Ni - Co - As - Ag/Bi deposit, Bohemian Massif, Czech Republic: fluid inclusion and stable isotope constraints

Original language description

The Zálesí vein-type deposit is hosted by Early Paleozoic high-grade metamorphic rocks on the northern margin of the Bohemian Massif. The mineralization is composed of three main stages: uraninite, arsenide, and sulfide. The mineral assemblages formed atlow temperatures (~80 to 130°C, locally even lower) and low pressures (<100 bars). The salinity of the aqueous hydrothermal fluids (0 to 27 wt.% salts) and their chemical composition vary significantly. Early fluids of the oldest uraninite stage containa small admixture of a clathrate-forming gas, possibly CO2. Salinity correlates with oxygen isotope signature of the fluid and suggests mixing of brines [? 18O around +2? relative to standard mean ocean water (SMOW)] with meteoric waters (? 18O around -4? SMOW). The fluid is characterized by highly variable halogen ratios (molar Br/Cl?=?0.8?x?10-3 to 5.3?x?10-3; molar I/Cl?=?5.7?x?10-6 to 891?x?10-6) indicating a domin
