| Abstract | The area of the Upper Silesian Coal Basin (USCB) is one of the best geothermally explored areas in Poland. Due to extensive coal exploration drilling the thermal field of the basin has been directly established down to the depth of 1000 Ò 2000 m. Below this depth the field is estimated basing on results of calculations of the heat flow density. The values of heat flow in the basin vary from 50 mW/m2 Ò 90mW/m2. Positive heat flow anomalies have been identified in the neighborhood of faults parallel to latitude. They are situated in the ÿory Ò Jawiszowice and Bzie-DÕbia Ò Czechowice zones, where tectonothermic reactivation was active during the early alpine orogenic phases. The relatively high geothermal temperatures, measured within the depth reached by boreholes, are perspective in respect of exploitation of the geothermal energy. |
