The stratigraphic subdivision of albsig deposits of the mountains of Culcutta

Cretaceous deposits in Central Kyzylkum are widely developed. They border the Paleozoic outcrops in broken cities in the cities of Bukantau, Auminzatau and Kuldzhuktau, Aristantau, Tamdytau. On the rocks of the Paleozoic basement, they lie transgressively with stratigraphic and angular disagreement from Apt in the west to Turon in the east. In the sediments, suites are identified, compared with complexes of organic residues with a common stratigraphic scale. Cretaceous deposits of the Central Kyzyl Kum contain complexes of ammonites, bivalves, foraminifera allowing correlation with the local and general stratigraphic scales. In the region of the Kuldzhuktau, Beltau and Auminzatau mountains, Cretaceous deposits are represented by various facies, mainly marine continental and less often lagoon formations, and they contain a wide range of minerals.
