	The results of comparative lithofacial analysis of the Middle Jurassic deposits of the Middle Caspian Basin perspective for hydrocarbons are presented. The detailed correlation of lithostratigraphic units of stratotype and key sections of the Middle Jurassic of the Eastern Caspian Basin was substantiated on the basis of stratigraphic scheme of the Middle Jurassic deposits of the region refined in recent years. Comparative analysis of lithofacial characteristics of the Jurassic deposits has considerably clarified the view on the completeness of sections in the different structures of the region, and set breaks in sedimentation process and their time range, especially for offshore area. The similarity of the Early Jurassic deposits in water and coastal areas of the Eastern Caspian Sea, the part of the section which is the most perspective for searching non-anticlinal traps. Key words: key section, formation, lithostratigraphic units, lithology, facies, condition of sedimentation, Middle Jurassic, Middle Caspian, East Caspian.
