Abstract

V originále

Post-Variscan Zn, Pb, Cu vein mineralisation 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 exerted by the faults. Eutectic temperature and crush-leach analyses indicate H2O-NaCl-CaCl2 type of basinal brines. Homogenization temperatures regionally decrease from 147 to 80C and salinities from 26.5 to 17 wt.% eq.NaCl. Temperatures correlate well with an increase of d18O values from 15.5 to 22.5 SMOW and d13C values from -5.6 to -3.1 PDB.
