(2001)The distribution of rock-forming and accessory minerals, major and trace elements in silty-sandy rocks along the tectonic profile was estimated from analyses of composite samples made up of 14000 individual samples, ...
-
(2001)The turnover of water and 18O in the outer terrestrial sphere is investigated considering mantle degassing, subduction zone processes, hydrothermal circulation at spreading centers, seafloor alteration, and continental ...

-
(2000)The Baltic Sea, particularly its southeastern part, is discussed in the paper. Investigations of regional character as well as specialized studies in the area are reviewed. General historical works are mentioned briefly. ...
-
(1992)Cenozoic volcanic rocks sampled during the 1989 Sino-French Kunlun geotraverse have been analyzed to constrain the origin of widespread Tertiary to Neogene Tibetan basic magmatism. Samples ranging from phonotephrites to ...
-
(1999)A detailed study was made of the oceanic 187Os/186Os variation through the Cenozoic by using a hydrogen peroxide leaching procedure on a pelagic clay core from the North Pacific (Long Lines-44 GPC3). A 6% H2O2 solution was ...
-
(1988)This study presents an analysis of the interrelations between 700 earthquake foci (with M = 6-8 and M > 8) for the period from 1900 to 1980 and fault tectonics and neotectonic deformations in the territory of new folded ...
-
(2001)The paper presents new details of the structure of the basement and sedimentary cover of the southwestern edge of the North Baikal basin. The basement structure involves smaller-scale structures (Maloe More basin, Zama ...
-
(1993)The Baikal rift depression, located in southeastern Siberia, is one of the best investigated intra-continental rift structures in the world. In addition to being the site of comprehensive studies by Russian geo-scientists ...
-
(1998)Three main stages related to major transgressive-regressive cycles of the development are recognized in the Late Cenozoic history of the Arctic Ocean: the Miocene-early Pliocene (regressive), late Pliocene-Eopleistocene ...
-
(2003)Graphoglyptids, a characteristic component of the Nereites ichnofacies, are patterned, mainly meander-, star-, and net-shaped trace fossils, which reveal complex burrow systems used most likely for trapping of meiobenthos ...
-
(2001)The tungsten distribution in intrusive rocks of the region was studied based on analysis of ~250 composite samples combined from more than 900 individual samples. The average W content in the Paleozoic granites and ...
-
(2004)The Baikal region is located in a single climate zone and includes the Baikal foredeep on the eastern margin of the Siberian craton and the Baikal rift evolving at the western boundary of the Baikal orogenic area. Late ...
-
(2004)Изучены корреляционные зависимости открытой пористости и проницаемости терригенных пород по геологическому возрасту и тектонической активности. По геологическому возрасту породы разделены на три группы: Kz, Mz, Pz, а по ...
-
(2004)На территории Юго-Западного Приморья изучена средне-позднекайнозойская последовательность магматических пород от основного до кислого состава, определен их возраст, измерены концентрации микроэлементов методом ICP MS и ...
-
(2004)The morphostructural subdivision of the White Sea region is based on morphostructural analysis of bathymetric charts, space image interpretation, data on seismicity, recent movements of the earth crust and other ...
-
(2003)During the Meso-Cenozoic time, changes of climate resulted more than once in that exogenic morphogenesis types replaced one another and relief underwent restructuring. It should be noticed, however, that though new land-forms ...
-
(2002)Произведен сейсмофациальный анализ верхнекайнозойских осадочных систем северо-восточной части Черного моря. На сейсмических разрезах изучены геометрия и распространение речных и дельтовых отложений, бугристых клиноформ, ...
-
(2002)На базе новых данных впервые предложена схема расчленения палеоген-неогеновых вулканогенно-осадочных образований Ивановской депрессии - кайнозойской тектонической структуры, расположенной на южной окраине Ханкайского ...
