[1] Holocene deposits of the caspian sea /  Bezrodnykh, . Yu,  Sorokin et al. // IGCP 610 Third Plenary Conference and Field Trip “From the Caspian to Mediterranean: Environmental Change and Human Response during the Quaternary”, Astrakhan, Russia. Proceedings / Ed.: A.Gilbert, V.Yanko-Hombach, T.Yanina. — MSU Moscow, 2015. — P. 34–36. The presented materials reflect the regressive-transgressive cycle of the Caspian Sea development during Holocene. After the maximum of the Late Khvalynian transgression about 12 thousand years ago the fast lowering of the sea-level began, it was the Mangyshlakian regression. About 11,5 cal.ky it settled down on a bottom site with modern depth of 10-12 m. The minimum of regression occurred about 9 cal.ky in the southern part of the studied area between isobaths of 35-50 m. After that time the sea-level rise connected with development of the New Caspian transgression began. About 7-8 cal.ky the final filling of the Mangyshlakian cuttings took place in the middle part of the shelf (depth of 10-12 m). After that the New Caspian deposits created the universal cover on all square of the modern shelf. Their consecutive accumulation interrupted by 2 stages of the sea-level lowering, shown in formation of the New Caspian cuttings.
