Abstract
Subvertical and subhorizontal bodies were identified in the South Caspian Basin. They are a new class of geological structures with a complicated form, which can serve as migration pathways and hydrocarbon accumulation zones. The basin incorporates a few autonomous sources of oil and gas occurrences with their own distribution areas and spatial-temporal evolution. HC generation sources are displaced relative to each other. The lower boundary of the oil and gas occurrence reaches depths of more than 12-15 km, while the upper boundary of the 'oil window' is confined to hypsometric depths of 5-7 km. [ABSTRACT FROM AUTHOR]
