The objective of this paper is to compare the data from 12 boreholes and evaluate the extent of expected burial and uplift. 295 new Rock Eval measurements were performed. The maximum pyrolytic temperature (Tmax) varies from 423 to 525 °C. The correlation of the Tmax and random vitrinite reflectance (Rr) demonstrated the linear increase of both parameters within the observed rank. Thus the Tmax could be used as a maturation parameter. A comparison of the curve inclination for vitrinite reflectance and maximum pyrolytic temperature indicated that the regional paleo-heat flow pattern was uniform during the period from the Visean to the Westhpalian. The observed regional differences in maturation patterns are linked to the tectonic features described in the area. Based on the results of the 1D model, the regional rank distribution can be correlated with an increased thickness in the missing units, rather than with changes in the geothermal gradients. The regional evaluation throughout the studied area reveals the burial depth of 1 800 to 3 000 m. The heat flow scenario used in the 1D model begins from 80 mW.m-2 during the Paleozoic decreasing to 52 mW.m-2. The following thermal and subsidence evolution did not change the thermal maturity pattern received during Carboniferous burial. ER -
