Bitak Formation is located within Simferopol area. It is presented by badly sorted conglomerates. Lithological description of conglomerates is given. New data about age of the clastic zircons are presented. The possible age of Formation is discussed. It is assumed that Bitak Formation is older than Late Bajocian volcanic rocks and is younger than deposits of Tavrik Formation ant it analogs. Bitak Formation was accumulated in the pull-apart basin. A few basins of the such type are detected in the Crimea. It is assumed that Bitak basin is located at the base of Middle Jurassic arc-island complex of Crimea.
