Pre-caspian Paleozoic Deposits Modern Structure Formation Condition

Annotation. Seismic works and deep boring materials analysis points out penecontemporaneous formation of Astrakhan-Aktubinsk uplift zones (AAUZ) and absence of cuttings at the culms of atoll like carbon-bearing solid masses as of Tengiz type. Soline thikness accumulation of Kungurian age tookplace at deep-water basin (the depth in the central areas of Pre-Caspian lacune exceeds 1,5 km). Seismic works materials interpretation within AAUZ limits assumes existing of trottoir s at docungur cuttings. Coincidence in plane of these “ reefs” is seen and salt-dome structure s that contradicts peculiarities of such formations
