Modern basins in this region contain relics of palaeo-basins of a certain tectonotype formed in varying geodynamic regimes. Petroleum potential estimates of the Western Arctic vary broadly—from 34.7 to more than 100 billion tons of oil equivalent with the share of liquid hydrocarbons from 5.3 to 13.4 billion tons of oil equivalent. At each stage of the development of palaeo-basins, favourable geological, geochemical and thermobaric conditions have emerged and determined the processes of oil and gas formation, Citation: Egorov, A.S.; Prischepa, migration, accumulation, and subsequent redistribution between different complexes.

Late Frasnian Atrypida (Brachiopoda) from the South Urals, South Timan and Kuznetsk Basin (Russia). - Acta Palaeontologica Polonica 43,2,305-344. Late Frasnian AĘpida @rachiopoda) from the South Urals, South Timan and Kuznetsk Basin in Russia (east Laurussian and south Siberian shelf domains in Devonian time) reveal significant geneńc and specific diversĘ in the broadly defined Frasnian-Famen- nian (F-F) bio-crisis time. Eighteen species of aĘpid brachiopods have been recorded, representing 4 subfamilies and 10 genera. The new genus GibberosatrypaMarkovskii & Rzhonsnitskaya, and the new subgenus Spinatrypa (Plicspinatrypa)Rzhonsnitskaya are proposed. Four new species Spinatrypina (Spinatrypina) sosnovkiensis Yudina, Spinar rypa (Plicspinatrypa) rossica Rzhonsnitskaya, Iowatrypa nalivkini Rzhonsnitskaya & Sokiran, and Cartnatina(?) biohermica Yudina are described. The representatives of the Vańatrypinae (including especially conrmon Desquamatia (Desquamatia) alticolifur- mis), Spinatrypinae (Spinatrypina) andAtypinae(Pseudoatrypa,?Costatrypa) arewide- ly distributed in the studied regions. The Pseudogruenewaldtiinae are represented by Iowatrypa artdPseudogruenewaldtla, of which the first is distributed worldwide, where- as the only undoubted species of the second is resfficted to South Timan, and probably represents a localized latest Frasnian descendant of lowatrypa. The decline phase of aĘpid development was controlled by a variety of environmental factors tied to the globalKellwasser events, although it was not directĘ triggered by anoxic conditions. The investigated atrypid brachiopods, which were all confined to lower latitudes, disappeared duńng the F-F mass extinction, independently of their environmental and biogeographic settings.

It shows that the organic matter of oil-generating deposits is at the close stages of thermal maturity, which are within the early and middle stages of the oil window. Five groups of oils have been recognized, three of which were generated by organic matter of Domanik deposits and the other two formed from organic matter of another source. Most of the studied oil samples contain derivates of isorenieratene indicating that the organic matter of oil source rocks formed in the photic-zone anoxia of the paleobasin. © 2017, V.S.

Over a decade (2003-2015) of satellite data of sea-ice extent, sea surface temperature (SST), and methane 11 (CH4) concentrations in lower troposphere over 10 focus areas within the Barents and Kara Seas (BKS) were 12 analyzed for anomalies and trends relative to the Barents Sea. Large positive CH4 anomalies were discovered around 13 Franz Josef Land (FJL) and offshore west Novaya Zemlya in early fall. Far smaller CH4 enhancement was found 14 around Svalbard, downstream and north of known seabed seepage. SST increased in all focus areas at rates from 15 0.0018 to 0.15 °C yr-1, CH4 growth spanned 3.06 to 3.49 ppb yr-1. 16 The strongest SST increase was observed each year in the southeast Barents Sea in June due to strengthening of 17 the warm Murman Current (MC), and in the south Kara Sea in September. The southeast Barents Sea, the south 18 Kara Sea and coastal areas around FJL exhibited the strongest CH4 growth over the observation period.

The study area is divided into the central sub-basin and the NE sub-basin. The NE sub-basin is positioned in the former disputed area between Norway and Russia. Salt diapirism and the formation of pillows attached to the basin margin make the Nordkapp Basin one crucial example of salt tectonics in the southwestern Barents Sea. The objective of this thesis is to study the salt distribution and evolution of the salt structures in the northern part of the Nordkapp Basin. The main dataset is 2D seismic reflection lines that are used in combination with filtered gravity data, selected time-slices from a pseudo-3D cube and well data. The rift basin architecture in the Nordkapp Basin is characterized by a wide fault zone of short densely-spaced fault segments. The lateral continuity of the fault segments increases upwards from the Late Paleozoic level.

Clark and Prof. Dr. Hans-Peter Bunge for all the support and guidance over the last years. I am very thankful for everything you taught me as a researcher and as a person. Also, I would like to thank my parents for always helping me in everything I do. Your example of dedication, hard work and passion to learn has always been my main inspiration in work and life. This thesis would be impossible without the help of Prof. Dr. Anke Friedrich, Dr. Lorenzo Colli, Dr. Stefanie Rieger and Dr. Christoph Moder. Thank you very much for the knowledge you gave me and for your contribution and support during this project. And, of course, thanks to my beloved friends and family: to the family Schmidt for being my home in Munich and to Bernardo and Teodora for making my PhD years joyful. Summary Motion of the lithospheric plates is a reflection of the convective circulation of the Earth’s mantle. Plate divergence is attributed to the mantle upwellings, while plate convergence to the mantle’s downwellings.

The analysis of the data gave us the possibility to study the dynamics and hydrological structure of the southwestern Kara Sea basin. The main elements of the gen eral circulation are the following: the Yamal Current, the Eastern Novaya Zemlya Current, and the St. Anna Trough Current. All these currents are topographically controlled; they flow over the bottom slopes along the isobaths. The Yamal Current begins at the Kara Gates Strait and turns to the east as part of the cyclonic cir culation.

Net erosion values vary from 0 to more than 3000 m. The processes have important consequences for the petroleum systems. Reservoir quality, maturity of the source rocks and the migration of hydrocarbons are affected by the processes. Owing to changes in the PVT conditions in a hydrocarbon-filled structure, uplift and erosion increase the risk of leakage and expansion of the gas cap in a structure. Understanding of the timing of uplift and re-migration of hydrocarbons has been increasingly important in the exploration of the Barents Sea. Ideas on uplift in the Barents Sea region can be traced back to have been over-stressed (Dore´ & Jensen 1996; Ohm et al. 2008). Fritjof Nansen (1904).
