Biostratigraphic characteristics of Sarmatian sediments in South-eastern Gobustan is presented according to the data of Shaigler-Gaibler section; the systematic composition and characteristic complexes of microfossils – foraminifers, ostracods, otolites and the fish remnants are defined. As a result of the biostratigraphic division of the section carried out, it was revealed that the sediments of Sarmatian stage participate in the geological structure of Shaigler-Gaibler anticline; there are no Upper Sarmatian sediments in the section.
The scheme of division of Sarmatian sediments in Shaigler-Gaibler sections which may be applied for the further geological surveys in the other areas of South-eastern Gobustan, has been developed.
The results obtained may be used for the biostratigraphic research of deeply buried Miocene sediments of Western edge of South Caspian.
