Parent fluids of the zinc and lead ores from the Silesia-Cracow region

Abstract

Fluid inclusions in sulfide minerals (sphalerite, wurtzite) of the zinc and lead ores from the Silesia-Cracow region, Southern, Poland, bear water solution (brine) and liquid and gaseous hydrocarbons, probably extracted from wall rocks of ores. These ores have formed at temperature close to homogenization temperature of inclusions, ranging from 92 to 138°C.
