Abstract

RESULTS OF STUDIES ON THE CARBONIFEROUS IN THE LUBLIN TROUGH Summary Geological studies on the Lublin Trough, carried out by the Geological Institute, supplied new data on lithological profile of the Carboniferous, extent and thickness of individual members of the Carboniferous, character of phytogenic sedimentation and degree of metamorphism of coals. The studied area is situated south-west of the proven resources in the Lublin Coal Basin. The recorded Carboniferous section comprises strata from the Namurian A to Westphalian C: those of the Komarów, Bug, Kumów and Lublin beds, occurring in sedimentary continuity. Top surface of the coal-bearing formation is erosional in character and overlain by strata of the Jurassic, Cretaceous and Quaternary, 700 to 1,100 m thick. Within the boundaries of the Lublin Trough, Carboniferous formation is downwarped at great depths than in platform part of the basin, and its individual lithostratigraphic members display increase in thickness. The Carboniferous rests here on various members of the Devonian. Major coal resources of the Lublin Coal Basin are related to the Lublin Beds. The strata are mainly preserved in structural depressions. In the perspective area, differentiated within boundaries of the Lublin Trough (Fig. 1), 760 km2 in area, perspective resources occurring at depths down to 1,500 m (Polish mining categories D1 and E) are estimated at about 10.3 milliards t. Coals found there belong to the types 31-34. Top surface of gaseous-coaky coals of the type 34 plunges north-westwards, from 800 m in the borehole Rejowiec IG-3 to c. 1,700 m in the borehole Lublin IG-2.
