COLD AND WARM TRANSGRESSIONS OF THE CASPI AN SEA

Both ''cold'' (Baku, Early Khazarian (Gyurgyan) and Khvalynian) and '' warm'' (Urundzhik, Late Khazarian and New Caspian) transgressions are recorded in the history of the Caspian Sea. The first ones correspond to the coolings and glaciations of the Russian Plain, while the latter ones occured during interglacial periods, ''Warm'' transgressions cor respond to the large regressive epochs of the Caspian Sea and were cha racterized by relatively small sea-level rise and flooded area.
