-
(1998)The late Pleistocene-Holocene deposits are studied in 12 piston-core sections sampled at the continental slope and in the deep part of the Black Sea within the Adler-Tuapse test area. In four of these sections, the Neoeuxinian ...
-
(1998)Changes in composition of planktonic foraminifers in nine cores of bottom sediments obtained from different areas of the Sea of Okhotsk were analyzed in order to reconstruct the history of climate and circulation of the ...
-
(2002)Bottom deposits of four lakes in the central part of Buryatia (51-54°N, 106-112°E) were subjected to the pollen and radiocarbon analyses. The data obtained elucidate development of regional and local Holocene vegetation ...
-
(2001)The stable isotope and trace element geochemistry of ostracode shells from Lake Issyk-Kul, Kyrgyzstan, provide an important new paleoclimate record for central Asia. The δ18O, δ13C, Sr/Ca, Mg/Ca and U/Ca composition of ...
-
(1998)The studied objects represent the lacustrine bottom deposits in the southeast of the Kola Peninsula and the peat bed in the Cape Rybachii, exemplifying the northernmost occurrence of this substance in the European part of ...
-
(2004)Intercept-based methods of generating a point estimate of a calibrated radiocarbon date are very popular, but exhibit undesirable behaviour. They are highly sensitive to the mean of the radiocarbon date and to adjustments ...
-
(1999)In 1996, boreholes BDP-96-1 and BDP-96 penetrated the bottom sediments of Lake Baikal. From the lithological and geochemical correlation of the sediments, the loss from the upper layer of sediments in the cores is estimated: ...
-
(2004)The global climate changings at the end of Pleistocene led to extinction of the typical representatives of Mammoth fauna–mammoth, woolly rhinoceros, wild horse, bison, muskox, cave lion, etc.–on the huge territories of ...
-
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 ...
-
(2004)The study of Holocene deposits from northwestern Pacific Islands is very important for understanding the natural development of the area in the context of oceanic climate, strong microclimate variability, and the influence ...
-
(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)A detailed description is presented of the statistical patterns of climate forcing of tree growth (annual maximum latewood density and ring-width time series), across a network of 387 specially selected conifer sites that ...
-
(2004)A sediment core from Lake Pichozero (61°46'; N, 37°25'; E 118m a.s.l.) provides information on the environmental and climatic conditions in southeastern Russian Karelia during the Lateglacial and early Holocene (12 800-9300 ...
-
(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 ...
