Post-magmatic hydrothermal mineralization associated with Cretaceous picrite (Outer Western Carpathians, Czech Republic): interaction between host rock and externally derived fluid

Original language description

Mineralogy, fluid inclusions, C, O, S, Sr isotopes and trace elements have been studied in amygdules and veins hosted by Lower Cretaceous picrite at the Hončova hůrka Hill. Dolomite, magnesite, siderite, quartz, calcite, chlorite, glauconite, fluorite, barite, pyrite and millerite form the mineralization. The parent fluids were low-temperature ({50-170 °C), low salinity (0.4-3.7 wt. % NaCl eq.) aqueous solutions with d18O, d13C and d34S values of 0/+14 ? SMOW, 0/-9 ? PDB a ~0 ? CDT, respectively, and initial 87Sr/86Sr ratios much more radiogenic (0.7060 to 0.7068) than host picrite (0.7042 and 0.7046). Fluids were derived from mixing of seawater with diagenetic waters produced by dewatering of clay minerals in surrounding flysch sediments.
