Tectonic Scheme

The evolutionary-genetic method, whereby modern sedimentary basins are interpreted as end-products of a long geological evolution of a system of conjugate palaeo-basins, enables the assessment of the petroleum potential of the Western sector of the Russian Arctic. 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, migration, accumulation, and subsequent redistribution between different complexes. The most recent stage of basin formation is of crucial importance for the modern distribution of hydrocarbon accumulations. The primary evolutionary-genetic sequence associated with the oil and gas formation regime of a certain type is crucial for the assessment of petroleum potential. Tectonic schemes of individual crustal layers of the Western sector of the Russian Arctic have been compiled based on the interpretation of several seismic data sets. These schemes are accompanied by cross-sections of the Earth’s crust alongside reference geophysical profiles (geo-traverses). A tectonic scheme of the consolidated basement shows the location and nature of tectonic boundaries of cratons and platform plates with Grenvillian basement as well as Baikalian, Caledonian, Hercynian, and Early Cimmerian fold areas. Four groups of sedimentary basins are distinguished on the tectonic scheme of the platform cover according to the age of its formation: (1) Riphean-Mesozoic on the Early Precambrian basement; (2) Paleozoic-Cenozoic on the Baikalian and Grenvillian basements; (3) Late Paleozoic-Cenozoic on the Caledonian basement; (4) Mesozoic-Cenozoic, overlying a consolidated basement of different ages. Fragments of reference sections along geo-traverses illustrate features of the deep structure of the main geo-structures of the Arctic shelf and continental regions of polar Russia.

Dynamics Problems

The deep structure and formation of the North Caspian (Precaspian) depression have not been fully understood due to the scarcity of depth studies at 18–22 km. The existing concepts and hypotheses are clearly insufficient to interpret the unexplained facts. New approaches and research efforts are necessary to solve the old problems. The current state of the depression deep structure problems is reviewed, and the existing explanation flaws are demonstrated. The depression consolidated crust has oceanic and riftogenic origin as it has been suggested by the author before. This explanation is supported by the Astrakhan deposit D-2 deep well core data. The Astrakhan-Aktobe zone arched uplift genesis, formation and role in the carbonate platforms emergence are discussed. Deep geothermy and fluid dynamics problems, as well as recent geophysical data are considered in view of the North Caspian depression hydrocarbon prospects.

Bu çalışmada, bir ‘sürgün şair’ olarak anılan Özkan Mert’in Ülkesinden Ayrılan Bir İşçinin Türküsü ve Bir Mültecinin Mektubu şiirleri göstergebilimsel bir yaklaşımla yeniden okunmaya çalışılacaktır. Özellikle farklı imgesel yapıları ve farklı bir dil kullanımını içinde barındıran ve bir ‘dünyalı şair’ olarak da anılan Özkan Mert’in şiirlerini biçimsel ve içeriksel yapılarıyla ele almak, son zamanlarda çokça tartışılan ‘sürgün edebiyatı’ ile ilgili görüşlere de katkı sunacaktır. Şiirler çözümlenirken, yüzeysel yapıdan derin yapıya doğru ilerleyen tümdengelimci yöntem izlenecek ve en son aşamada şiirler anlamsal yapılarıyla karşılaştırılmaya çalışılacaktır.ENGLISH ABSTRACTThe Projection of Exile in Poetry: A Semiotics Approach to Özkan Mert’s poems titled Ülkesinden Ayrılan Bir İşçinin Türküsü and Bir Mültecinin Mektubu In the current study, it will be tried to reread the poems titled Ülkesinden Ayrılan Bir İşçinin Türküsü and Bir Mültecinin Mektubu of Özkan Mert, who is known as an exiled poet, with a semiotics approach. Considering the poems of Özkan Mert, who is known as an “poet of the world” and contains different imaginary structures and a different language usage, with their stylistic and contextual structure will also make contribution to the “exile literature” that is argued recently. During the analysis of poems, the deductive method proceeding from the superficial structure to deep structure will be practised and finally the poems will be compared about their semantic structures.Keywords: Özkan Mert; Semiotics; Exile Literature; Superficial Structure; Deep Structure

Biographical Information

In 1911 Aleksander Stenbock-Fermor, a Russian aristocrat, offered the Muséum National d'Histoire Naturelle, Paris, a well-preserved mammoth from Lyakhowskiy Island, New Siberian Isles. This paper presents a hitherto unpublished memorandum that Stenbock-Fermor addressed to Edmond Perrier, the Museum's director, which related the circumstances surrounding the discovery, removal and transportation of the mammoth from Siberia to St Petersburg and thence to Paris. The paper also presents some biographical information on Konstany Wołłossowicz, who explored Siberia and who organized the expedition to Lyakhowskiy Island in order to bring the mammoth to Europe.
