The comparison of microfacies character of Westphalian A and B coals in Upper Silesian and Lublin Coal Basins

摘要: The microfacies character of coal seams belonging to Westphalian A and B lithostratigraphic units from Upper Silesian Lublin Basins was established according results microlithotype analises. comparison microlithotypc composition analysed coals both basins suggests that they have developed in similar facies conditions generally characterized by intensive subsidence. high ground water level limited oxygen supply. presence dark, spotty vitrinite often associated with syngenetic pyrite as well abundant, partially decomposed exinite suggest more anaeorobic comparing those Basin. domination clarite type vi trite content Orzesze Beds possibility their utilization liquifaction processes.
