The dynamics of genesis of organic substance in oil shales
O.R. AbbasovThe paper deals with the structure and origin of organic substance (OS) in the oil shales of Guba (Shabranchay and Velvelechay) and Ismayilli (Dially field) regions of Azerbaijan relating to the Paleogene-Miocene sediments. According to the results of geochemical studies of oil shales, including the step-by-step thermal analysis of kerogene, it has been revealed that the major mass changes in the interval of 300500 0C temperature. Thus, changing of the structure of aliphatic organic substances occurs at low temperature, but an aromatic at high ranges. Due to the results of pyrolysis of OS, the first stage is the forming of oil-like substances and pyrolysed water; by the increasing of temperature take place gas formation and the last stage coal formation.
