Various geodynamo models proposed recently in the different ways explain the processes of geomagnetic field generation and its evolution over the course of the geological history. The testing capabilities of these models are strongly limited, inter a

Two sediment cores from the Knipovich Ridge in the Fram Strait have been studied to examine paleoceanographic and climatic changes in the Polar North Atlantic during the late Middle and Late Pleistocene. As inferred from the data on foraminifers, nan

A stratum of glacial diamictites with thickness of up to 160 m at the basement of the sedimentary cover, overlain by a series of cap carbonates up to 40 m thick is described for several boreholes in the central regions of the Siberian platform. The i

Variations in the carbon isotope composition in gases and waters of mud volcanoes in the Taman Peninsula are studied. The δ13C values in CH4 and CO2 vary from −59.5 to −44.0‰ (δ13Cav = −52.4 ± 5.4‰) and from −17.8 to +22.8‰ (δ13Cav

The Cretaceous sections of the eastern Caucasus contain rich in organic matter (OM) sediments corresponding to the late Cenomanian Oceanic Anoxic Event 2. They are marked by positive δ13C and negative δ18O isotopic anomalies, which are characterist

Seismoacoustic profiling and sonar survey of the North Caspian water area revealed in some areas signs of intense release of methane from the sedimentary sequence. This fact was also supported by submarine videorecording data. Such sites are characte
