dc.description.abstract | Coal seams in the Upper Silesian Coal Basin vanish within the Carboniferous Upper Silesian
Sandstone Series and below an unconformity marking the Carboniferous top surface. Changes in the
geochemical, mineralogical, petrological and palynological characteristics of gangue rocks associated
with the vanished seams record what happened. The observed changes could have been caused
by (1) coal-seam paleofire, (2) peat combustion, (3) igneous intrusion, (4) metasomatism and/or
(5) weathering. Multifaceted research on samples collected at the Jas-Mos mining area, a part of
the operating Jastrz˛ebie-Bzie Coal Mine that are representative of different geological settings in
the northern and southern parts of the mining area, point to intra-deposit paleofire as the most
plausible reason for the disappearance. Biomarkers enabled recognition of differences in heating
duration and oxygen access. Coal seams in the south burned quickly with abundant oxygen supply.
Seams in the north pyrolyzed for an extended time under conditions of limited oxygen. Though
other methods used proved less sensitive, all confirmed low (100–150 C) paleotemperature heating.
Overall, the reason for the local disappearance of the coal seams, making their exploitation difficult
and unprofitable, can be assigned to a variety of different processes in a complex overlapping history
of variable weathering, heating due to local endogenic fires and, probably, earlier peat combustion. | pl_PL |
