This phenomenon produces large deformations in the upper crust that are observed in some rift valleys. Many past basins on continental crust were strongly folded. The structure of their sedimentary cover was well studied in numerous sections. There are no deformations typical of stretching in the predominant part of the sections. Hence in most cases formation of the above basins was not caused by stretching. There are two main types of large deep basins on continental crust. The basins of the first type are formed in cratonic areas by large magnitude subsidence in a few m.y. Rapid subsidence without signifi­ cant stretching in cool areas may be explained by gabbro to eclogite transformation in the lover crust. Rapid transformation can arise under the upwelling to the crust of a hydrous low-velocity mantle of moderate temperature T'veOO^C. Sinking of dense eclogite into the mantle strongly attenuates the crust and lithosphere. That is why strong crustal shortening often occurs in such basins. The basins of the second type are deep cratonic sedimentary basins formed by compensated subsidence during the period of time of several hyndred m.y. of more. Their formation.can be attributed to slow eclo- gitization in the lowermost crust within the lithospheric layer of a high thickness^ 100 km. Intense crustual shortening does not take place in such basins, until rapid subsidence occurs in them. The basins of the above two types cover mush wider area than narrow continental rift valleys - typical structures produced by stretching. 3asic mechanisms for the continental crust subsidence premit to de­ termine geodynamic for the formation of hydrocarbon basina. 6 АРТЮШКОВ Е.В., Институт физики Земли Академии наук СССР,г.Москва;' БЕЭР М.А., Министерство геологии СССР, г.Москва, СССР МЕХАНИЗМ ОБРАЗОВАНИЯ' ГЛУБОКИХ ПРОГИБОВ НА КОНТИНЕНТАЛЬНОЙ КО? Е Образование крупных глубоких прогибов на континентальной коре боль­ шинство исследователей объясняет растяжением. Сильное растяжение приводит к большим деформациям в верхней части коры, которые наблю­ даются в ряде рифтовых впадин. Многие древние прогибы на континентальной коре были вовлечены в ин­ тенсивную складчатость. Строение их осадочного чехла хорошо изучено в многочисленных разрезах.основных фанерозойских складчатых поясов: АльпийскогоjУральского, Верхоянского, Аппалачей, Северо-Американских Кордильер, каледонид и герцинид Западной Европы. В подавляющем боль­ шинстве случаев в нём отсутствуют деформации, характерные для сильно­ го растяжения. Следовательно, образование таких прогибов,как правило, не было обусловлено растяжением. Выделяются два основных типа глубоких прогибов на континентальной ко­ ре. Прогибы первого типа формируются на платформах за несколько млн. лет в результате погружений большой амплитуды. Такие быстрые погруже­ ния без сильного растяжения в холодных областях можно объяснить пере­ ходом габбро в эклогит в нижней части коры. Быстрый переход возника­ ет при подходе к коре водосодержащей аномальной мантии с умеренной температурой Т~800°С. Последующий отрыв и погружение тяжелого экло- гита в мантию сильно утоняет кору и литосферу. Поэтому большинство таких прогибов в дальнейшем вовлекается в сильное сжатие. Прогибы второго типа это глубокие платформенные осадочные бассейны, образованные компенсированным прогибанием за время в сотни млн.лет и более. Их формирование можно связать с медленной эклогитизацией в нижней части коры, протекающей в пределах литосферы большой мощности ^100 км. Такие прогибы не вовлекаются в сильное сжатие до тех пор, пока в их пределах не происходит быстрого погружения, характерного для прогибов первого типа. Прогибы описанных типов покрывают в сумме много большую площадь, чем узкие континентальные рифтовые впадины - типичные структуры, образо­ ванные растяжением. Знание основных механизмов погружений.континентальной коры позволяет определить геодинамические условия образования нефтегазоносных

Thenkabail Received: 5 June 2016; Accepted: 17 October 2016; Published: 23 October 2016 Abstract: The paper discusses our studies of oil pollution in the Black and Caspian Seas. The research was based on a multi-sensor approach on satellite survey data. A combined analysis of oil film signatures in satellite synthetic aperture radar (SAR) and optical imagery was performed. Maps of oil spills detected in satellite imagery of the whole aquatic area of the Black Sea and the Middle and the Southern Caspian Sea are created. Areas of the heaviest pollution are outlined. It is shown that the main types of sea surface oil pollution are ship discharges and natural marine hydrocarbon seepages. For each type of pollution and each sea, regions of regular pollution occurrence were determined, polluted areas were estimated, and specific manifestation features were revealed. Long-term observations demonstrate that in recent years, illegal wastewater discharges into the Black Sea have become very common, which raises serious environmental issues. Manifestations of seabed hydrocarbon seepages were also detected in the Black Sea, primarily in its eastern part. The patterns of surface oil pollution of the Caspian Sea differ considerably from those observed in the Black Sea. They are largely determined by presence of big seabed oil and gas deposits.

    Tetrapod Localities from the Triassic of the SE of European Russia

    Earth-Science Reviews 60 (2002) 1–66 www.elsevier.com/locate/earscirev Tetrapod localities from the Triassic of the SE of European Russia Valentin P. Tverdokhlebova, Galina I. Tverdokhlebovaa, Mikhail V. Surkova,b, Michael J. Bentonb,* a Geological Institute of Saratov State University, Ulitsa Moskovskaya, 161, Saratov 410075, Russia b Department of Earth Sciences, University of Bristol, Bristol, BS8 1RJ, UK Received 5 November 2001; accepted 22 March 2002 Abstract Fossil tetrapods (amphibians and reptiles) have been discovered at 206 localities in the Lower and Middle Triassic of the southern Urals area of European Russia. The first sites were found in the 1940s, and subsequent surveys, from the 1960s to the present day, have revealed many more. Broad-scale stratigraphic schemes have been published, but full documentation of the rich tetrapod faunas has not been presented before. The area of richest deposits covers some 900,000 km2 of territory between Samara on the River Volga in the NW, and Orenburg and Sakmara in the SW. Continental sedimentary deposits, consisting of mudstones, siltstones, sandstones, and conglomerates deposited by rivers flowing off the Ural Mountain chain, span much of the Lower and Middle Triassic (Induan, Olenekian, Anisian, Ladinian). The succession is divided into seven successive svitas, or assemblages: Kopanskaya (Induan), Staritskaya, Kzylsaiskaya, Gostevskaya, and Petropavlovskaya (all Olenekian), Donguz (Anisian), and Bukobay (Ladinian). This succession, comprising up to 3.5 km of fluvial and lacustrine sediments, documents major climatic changes. At the beginning of the Early Triassic, arid-zone facies were widely developed, aeolian, piedmont and proluvium. These were replaced by fluvial facies, with some features indicating aridity.
