Fore-Sudetic Homocline
Opis:: Intense program of shale gas prospecting in the territory of Poland is currently on going. Among the steps towards better examination of dispersed organic matter (DOM) in clastic Carboniferous rocks of the basement of the Fore-Sudetic Homocline are petrologic studies. The paper provides data on the DOM composition, kerogen type determination, and identification of thermal maturity degree of Carboniferous rocks in the basement of the Fore-Sudetic Homocline. In general, organic matter from the Carboniferous rocks is represented only by vitrinite and inertinite. Such composition of DOM permits to define it as humic organic matter typical for kerogen type III. Carboniferous rocks display a high and very high degree of thermal maturity, expressed by a wide range of vitrinite reflectance values (from below 1.50% to above 5.50%).

Opis:: Raman spectroscopy and vitrinite reflectance measurements of dispersed organic matter from Carboniferous shales in boreholes in the northern part of the Intra-Sudetic Basin were used for thermal history reconstruction. Microscopic investigations have shown that the organic matter is dominated by the vitrinite maceral group. In analysed samples, organic matter shows a varied degree of thermal alteration determined by the mean random vitrinite reflectance (VRo) ranging from 0.72% to 3.80%. Mean apparent maximum vitrinite reflectance (R’max) values reached 4.98%. The full width at half maximum of D1 and G bands in Raman spectra are well-correlated with mean VRo and R’max. Thermal maturity in the boreholes shows a regular increase with depth. Geological data combined with Raman spectroscopy and mean vitrinite reflectance results indicate that the analysed Carboniferous strata reached maximum paleotemperatures from c. 110 to c. 265°C. The regional paleogeothermal gradient in the late Paleozoic was c. 80°C/km. The Variscan heating event presumably caused a major coalification process of organic matter. The Carboniferous–Permian magmatic activity must have contributed to high heat flow, adding to the effect of sedimentary burial on the thermal maturity.
