    In this dissertation geochemical characteristic of organic matter in the Mesozoic strata of central part of the Crimean Mountains from Aj-Petri and Jalta massifs was performed. The analysed sediments in most cases contains minimal quantity of organic carbon, usually below 0.2 wt.% and traces quantities of hydrocarbons. Rocks from all examine samples have weak hydrocarbon potential. Geochemical researches shows predominance II type of kerogen with admixture of kerogen type III. The thermal maturity changes within the interval from 0,6 to 1,7 in Ro scale or “oil window” and “gas window” range. The thermal modeling reveled, that received the “oil window” phase of the Upper Jurassic organic matter in the Aj-Petri and Jalta massifs took place in the Paleocene and increase in this phase of maturity lasted until the middle Eocene.
