(2000)The relicts of large meandering palaeochannels are found throughout the territory of the periglacial zone of the Last (Valdai=Weichselian) Glaciation on the Russian Plain. Channel widths of macromeanders can be 15 times ...
-
(1998)A tephrochronological study and radiocarbon dating of soil-pyroclastic sequences were carried out along a profile of Shiveluch Volcano-Chernyi Yar-Bering Islands. Ashes deposited by the largest Shiveluch eruptions (for the ...
-
(1999)Nineteen Holocene eruptive centers (cinder cones with lava flows and maars) were located and described in the Avacha horst and anticline zone west of the East Kamchatka volcanic area. A tephrochronological study and the ...
-
(2004)The deep-water sediments of Lake Baikal retain an uninterrupted record of the climatic and environmental variations of continental Asia in the Late Cenozoic (Baikal drilling project). The paleoclimatic record is based on ...
-
(1997)The climate of the Holocene is not well suited to be the baseline for the climate of the planet. It is an interglacial, a state typical of only 10% of the past few million years. It is a time of relative sea-level stability ...
-
(2001)One of the most pronounced environmental changes during the Holocene Baltic Sea history was the transition from the freshwater Ancylus Lake to the brackish water Litorina Sea. The establishment of brackish conditions during ...
-
(2001)By comparing the compositions of glacial and interglacial intervals of the Late Pliocene, Pleistocene, and Holocene from different parts of Lake Baikal, we demonstrate the use of the Baikal clay mineral associations as ...
-
(1998)In the Pleistocene-Holocene section of the Baikal deep-water sediments shales are periodically enriched with the siliceous shells of diatomic algae up to nearly pure diatomite. As the terrigenous shale-silty material is ...
-
(1989)The recent study of submarine volcanoes of the Kurile island arc on cruises of the R/V Vulkanolog revealed the distribution in space of all Holocene volcanoes here and, therefore, allowed them to be analyzed in connection ...
-
DYNAMICS OF SEA MAMMAL AND BIRD POPULATIONS OF THE BERING SEA REGION OVER THE LAST SEVERAL MILLENNIA (2004)The secular dynamics of sea mammal and bird populations of the Bering Sea region over the last several millennia are reconstructed. We identify osteological material from the cultural layers of ancient sea-mammal hunter ...
-
(2001)This work was aimed to study the bedding of Early Holocene sapropel and a thin (0.2-4 cm) layer of tephra enclosed in it at a distance of 5-8 to 13 cm above its bottom. The tephra consists of poorly rounded particles of ...
-
(2003)The stable-isotope stratigraphy of sedimentary organic matter and algal cellulose in cores from two lakes near treeline on the Kola Peninsula indicate changes in water and nutrient balance that correlate with inferred ...
-
(2003)Recent geological studies have revealed that the freshwater input to the Arctic Ocean was highly variable during the Holocene. In the present study, the in uence of mid-Holocene river runoff on large-scale Arctic ocean/sea-ice ...
-
(2001)North of the Arabian plate, active tectonics is characterised by both N–S compression and E–W extension associated with strike-slip faults. The Pambak–Sevan–Sunik fault (PSSF) zone in Armenia is one of the major active ...
-
(2001)Holocene Black Sea sediments recovered in 1988 and 1993 from box cores and gravity cores were analyzed geochemically, microscopically, and with backscattered electron imagery (BSEI) in order to determine the temporal, ...
-
(2003)In the southeast of Western Siberia within the zone of birch and pine forests in the Ob'-Tom' interfluve area, four new pollen diagrams from sites in different landforms (interfluve, terraces, floodplain, and ancient ...
-
(2001)Geomorphological investigations in the catchment area of the Baydragiyn river along the southern slope of the Khangay and in the Valley of the Gobi Lakes in western Mongolia provide evidence for Late Quaternary glaciations ...
-
(2002)Environmental conditions and productivity changes in the southeastern Okhotsk Sea have been reconstructed for the last 20 ka using planktonic and benthic foraminiferal oxygen isotope records and calcium carbonate, organic ...
