Šafanda, B. Žáková, G. Buntebarth] Summary: The coalification data of 12 boreholes in the Central Bohemian Basin are used to evaluate the paleotemperature gradients for the Upper Carboniferous period of the basin's development. Two versions of the burial history considered are supposed to yield an upper and a lower estimate. According to the more probable "lower” version, the average values of the paleogradient suggest an increasing tendency from west to east in the interval of 45-53K/km. The current geothermal gradients vary in the range of 28-35K/km. By combining the present thermal conductivity and the paleogradients, we have tried to estimate the Upper Carboniferous heat flow. Its values range from 96mW/m 2 to 117mW/m 2 . The results obtained can be compared with the paleogradient estimates in the Saar-Nahe Basin (F. R. of Germany). This region, which is similar with respect to the time of origin and tectonic pattern to the Central Bohemian Basin, displays on the average a slightly higher Permo-Carboniferous geothermal gradient of 60K/km.
