Nature of the North Caspian gravity anomaly

With the use of the method of complete geological reduction, it has been shown that the unique gravity anomaly that frames the Near-Caspian petroliferous basin in the south is related to the Lower Paleozoic volcanic-terrigenous complex that occurs at the base of sedimentary cover at a depth of 8-12...

Description
Summary:With the use of the method of complete geological reduction, it has been shown that the unique gravity anomaly that frames the Near-Caspian petroliferous basin in the south is related to the Lower Paleozoic volcanic-terrigenous complex that occurs at the base of sedimentary cover at a depth of 8-12 km. This complex was formed contemporaneously with spreading of the Ural-Turkistan ocean and mark a rift zone in the south of passive margin of the East European continent. The rift was conjugated with an ancient triple junction on the floor of the Ural-Turkistan paleocean.[PUBLICATION ABSTRACT]
