THE RELATIONSHIP OF RECENT VERTICAL MOVEMENTS TO THE MORPHOSTRUCTURAL PATTERN OF THE KAZAKH SHIELD (1992)The geodetic data on recent vertical crustal movements within the Kazakh shields is in good correlation with its development in the Holocene (according to a study of juvenile river terraces); they point to gradual transition ...
-
(2002)Midsummer (July) temperatures are reconstructed for the last 7500 years using the long ring-width chronology of Scots pine (Pinus sylvestris L.) from northern Finland. The chronology was built using regional curve ...
-
(1997)The classical model of faulting predicts that slip planes occur in two conjugate sets. Theoretically, more sets can be contemporarily active if pre-existing structures are reactivated in a three-dimensional strain field. ...
-
(2002)The Tunka rift valley extending from the SW termination of Lake Baikal by 200 km westward represents a series of large and smaller troughs separated by subordinate elevations. Inversely uplifted bedrock exposures exhibit ...
-
(2000)Three sediment cores from the Laptev Sea continental margin were investigated for their clay mineralogy by X-ray diffraction to study the fluvial sediment supply since the late Weichselian. In the study area, the clay-mineral ...
-
(2000)In order to reconstruct the depositional environment from the Laptev Sea continental slope and shelf during the past ~15,000 years BP maceral analysis was carried out on two sediment cores (PS2458-4, PS2725-5) and compared ...
-
(1990)To determine whether the dynamics of variation in chemical composition of ferromanganese nodules (PMN) depends on their geologic age, the authors used the composition of nodules growing on shark teeth. The latter have ...
-
(2001)Time-dependent variations in the physicochemical properties of pyrite were investigated in four sediment cores from the Black Sea. In the laminated, deep-basin sediments of Unit I and Unit II, >86% of pyrite particles are ...
-
(2000)Variations in sediment input and distribution to the Laptev Sea continental margin during the Holocene and Termination I could be identified based on radiocarbon dated magnetic susceptibility logs and sediment thickness ...
-
(2001)New pollen records and radiocarbon dates from two sites in the Yana River lowlands, Arctic Yakutia, Russia provide reconstruc-tions of vegetation and climate history of this region during the last 6400 yr. The #uctuations ...
-
(1998)Bottom deposits of the Dood Nuur (51°20′ N, 99°23′ E), Hovsgol Nuur (50°32′ 101°10′ E), and Gun Nuur (50°15′ N, 106°36′ E) lakes of northern Mongolia are analyzed and discussed. Data of pollen and diatom analyses are used ...
-
(1999)The phytomass (the biomass of terrestrial vegetation) is one of the main reservoirs of carbon, as carbon makes up approximately 0.45 of the phytomass by weight [Ajtay, G.L., Ketner, P., Duvigneaud, P., 1979. Terrestrial ...
-
(1987)Major slope failures are a significant degradational process at volcanoes. Slope failures and associated explosive eruptions have resulted in more than 20 000 fatalities in the past 400 years; the historic record provides ...
-
(2000)Microelement distribution in the upper (up to 5 m) Holocene-Upper Pleistocene sediments along the northern and southern sublatitudinal profiles located in the northern part of the Deryugin trough is discussed. The mathematical ...
-
(2004)The ingress of mollusk Cerastoderma glaucum (Cardium edule) into Caspian Sea in the Early and Middle Holocene i.e. before Mangyshlak regression is discussed. Published materials and field data are given, indicating the ...
-
(1984)A study of the ice wedge morphology possible to distinguish five different types of ice wedges, or combinations thereof.
-
(2004)The paper deals with the results of paleogeographical study of marine and deltaic sediments of the Black Sea’s shoreline of Taman’ peninsular, aimed to reconstruction of the local variation of the sea level changes and ...
-
(2003)The series of postglacial terraces surround the lake Imandra. Terraces of relative height -3 - - 11 m are built up with one stratum of limnoglacial deposits of Late Quaternary age. The sediment texture is characterised by ...
-
(1989)The efficient use of the natural resources of coasts essentially depends on how correct are the notions on the long-term evolution of the coastal zone. The concept that the SE Baltic coast evolution is controlled by a ...
