PALEOTHERMAL MISMATCH IN RIFTOGENIC BASINS - THE BASIS FOR HYDROCARBON PREDICTION ESTIMATION
The paper is meant to prove that structural reconstruction of riftogenic basinsisac companied with intensification of tectonic-hydrothermal activity. This is in control over mobility of gaseous-liquid hydrocarbons during their primary and lateral migration in the process of deposit formation. The intensity index of tectonic-hydrothermal activation is equal to the ratio of maximum paleotemperatures of gaseous-liquid inclusions to the paleotemperatures calculated from vitrinite reflectance values. When determine in the same interval sofa geologic section, this parameter reflects the level of paleothermal incongruity in the natural system. It maybe used to make predictive estimates of the areas for hydrocarbon materials. Inpromising riftogenic areas, with the source rocks in the temperature zone of 80-160°С due to conducive heating, the values of this parameter vary in the range of 1.4-2.3.
