Rare earth elements and yttrium geochemistry of dolomites from post-Variscan vein-type mineralization of the Nízký Jeseník and Upper Silesian Basins, Czech Republic

Original language description

Rare earth elements and yttrium geochemistry of dolomite from post-Variscan vein-type Zn-Pb-Cu mineralization was studied in the Nízký Jeseník and Upper Silesian Basins. Combined with crush-leach analyses of fluid inclusions, the study provided importantinformation on fluid-rock interaction, physicochemical and redox conditions during crystallization of the dolomite. The mineralization is hosted by Carboniferous siliciclastic rocks, representing Variscan flysch and molasse sedimentation. Dolomite samples contain highly variable contents of REE (between 18 and 295 ppm) and Y (between 17 and 95 ppm). REY patterns are divided into four different groups which differ in regional provenance, LREE vs. HREE enrichment/depletion and significance of Eu, Gd andY anomalies. These patterns can be the result of 1) precipitation of dolomite from near neutral fluids with important concentrations of complexing ligands as a main factor for the REY partitioning, 2) interaction of migrating fluids with
