The paper discusses modern views of the structure of the main producing plays in the southern Siberian Platform: Riphean, Vendian, and Lower Cambrian. The major zones of oil and gas accumulation have been distinguished. Forecast resources have undergone differentiated expert evaluation, and methods for their development have been recommended. © 2010.

We present a new chronology for the upper Miocene to Pliocene deposits of the Black Sea basin based on"high-resolution'magnetostratigraphic data coupled with 40Ar/39Ar dating from the 475m long Zheleznyi Rog section on the Taman Peninsula (Russia). This section comprises the stratigraphic interval of the Khersonian to Kimmerian regional stages of the Eastern Paratethys. Our magnetostratigraphic record is based on biogenic and early-diagenetic greigite components and yields a magnetostratigraphic sequence of 8 polarity zones. A volcaniclastic ash layer at the upper part of the Khersonian is radio-isotopically dated at 8.69±0.18Ma. The age of the Khersonian-Meotian transition arrives at 8.6 or 8.2Ma, which is significantly younger than earlier estimates. The new age has important consequences for the"Hipparion"datum in the Eastern Paratethys, and implies that all Vallesian fossil sites are younger than 11.2Ma. The Meotian stage has a total duration of 2.2 to maximum 2.6Myr, and is marked by multiple erosional events. The end of the Paratethys Sea is dated at 5.5Ma, when the Black Sea becomes isolated from the Caspian Sea, the Dacian basin and the Mediterranean. © 2011 Elsevier B.V.

Stratigraphy and Geological Correlation | Year: 2011
The first deep hole (Tsentral'naya-1) drilled on the Russian shelf of the Bering Sea in 2002 recovered the Cenozoic sedimentary section up to depths of 2785 m1 This paper discusses results from the log, core, and slime study. The section is composed of Paleocene-Quaternary sediments. It comprises nine sequences (from the top downward): upper Miocene-Pliocene sandy-silty; middle-upper Miocene tuffaceous-diatomite, silty-sandy, shale-siltstone, and coquina-sandstone-siltstone; Eocene-lower Miocene coaliferous and sandstone-shale; Paleocene-lower Eocene volcano-sedimentary. These sequences are correlated with onshore stratigraphic units. The section includes three large unconformities: at the base of the Pliocene (depth of 380 m, base of the Aleksandrovka stratigraphic horizon), at the base of the middle Miocene (depth of 1390 m, base of the Avtakul Horizon), and, presumably, at the base of middle Eocene (depth of 1390 m, base of the Tanyurer Horizon). The last unconformity is accompanied by a kaolinite weathering crust. The section drilled into by Tsentral'naya-1 Hole shows common features for the Cenozoic sedimentary cover through the entire Anadyr basin, despite its significant facies variability. © 2011 Pleiades Publishing, Ltd.

The approaches to the identification of petroleum systems and their possible use for forecasting the largest oil and gas fields in the offshore Russian Arctic are described. The significance of petroleum systems for forecasting at regional and local levels, using internal standards allowing determination of the size rank of free gas or liquid hydrocarbon fields in oil-gas complexes, are illustrated by examples from the Timan-Pechora and Barents-Kara oil-gas provinces. © 2011 The Geological Society of London.
