Abstract
Post-Variscan Zn, Pb, Cu vein minera-lisation occurs within the Lower Carboniferous siliciclastic rocks at the eastern border of the Bohemian Massif. Saddle dolomites are associated with this vein mineralisation and indicate a NW-SE oriented fluid flow through the Palaeozoic rocks. The major control on this fluid flow pattern is experted by faults. Eutectic temperature and crush-leach analyses indicate H2O-NaCl-CaCl2 type of basinal brines. Homogenization temperatures regionally decrease from 147° to 80°C and salinities from 26.5 to 17 wt.% eq. NaCl. Temperatures correlate well with an increase of_δ18O values from 15.5 to 22.5%. SMOW and_δ13C values from_−5.6 to_−3.1%. PDB.
