Composition of natural gas from the Zechstein Limestone (Ca1) strata of Rudna mine has been compared with the natural gas from Carboniferous, Rotliegend strata of the Fore-Sudetic Monocline and with gas generated from the organic matter of the Main Dolomite during hydrous pyrolysis experiments. The gas from Rudna mine is characterized by the normal methane-ethane-propane isotopic system which indicates formation in one stage from a single source rock probably of the Carboniferous age containing kerogen of mixed II/III type. Generation of the hydrogen sulphide resulted from the microbial sulphate reduction processes of the basal anhydrite has been proven by mineralogical and isotopic 13C/12C analyses of 12 carbonate and 34S/35S analyses of 14 sulphate samples. These samples were collected in the mine at the depth of about 900–1200 m at temperature range of 35–45°C and two samples of carbonates were taken from one core. |
