(1987)The rocks produced in the Quaternary cycle of volcanism in the GVTS (Gamchen Volcanotectonic Structure) can be subdivided into three phases, each representing a volcanic regeneration phase in the region: early Pleistocene ...
-
(1998)The eustatic component of relative sea-level change provides a measure of the amount of ice transferred between the continents and oceans during glacial cycles. This has been quantified for the period since the Last Glacial ...
-
(1999)The δ13C record of total organic carbon in the Lake Baikal core BDP-93-2 over the last glacial/interglacial transition shows remarkable correlation with atmospheric CO2 fluctuations and the negative isotopic shift of 3.5–4‰ ...
-
SEDIMENTARY MO ISOTOPE RECORD ACROSS THE HOLOCENE FRESH-BRACKISH WATER TRANSITION OF THE BLACK SEA (2005)Mo isotope data on Black Sea sediments spanning the transition from Pleistocene oxic–limnic conditions to the prevailing anoxic marine conditions are presented. Samples were taken from a gravity core collected at a water ...
-
(1996)In recently formed marine barite (BaSO4) separated from two equatorial Pacific cores 226Ra activity exceeds that of its parent 230Th by at least an order of magnitude, indicating radium uptake during barite precipitation. ...
-
(2003)The Volga delta differs from all other major deltas in the world by its extremely gentle onshore and offshore gradient (∼5 cm/km) and by being affected by the rapid sea-level changes of the Caspian Sea, at rates up to a ...
-
(2001)Morphological and biomorphic studies of a soil chronosequence in the Chechen depression of the Northern Caucasus, Russia, indicate soil evolution and plant successions during the second half of the Holocene. The chronosequence ...
-
(2000)The study of Upper Quaternary sedimentary sequences in the Pechora Sea by means of vibrocoring revealed three sediment units. The (youngest) sandy unit accumulated in marine environments later than 5000 years B.P. The ...
-
(2001)We present new data on the distribution and composition of n-alkanes (biomarkers) and humic acids in the Holocene and Pleistocene bottom sediments of Northern Baikal accumulated under different sedimentation and paleoclimatic ...
-
(2000)Two volcanic centers, South and North Cherpuk Volcanoes, were investigated on the Sredinnyi Range of Kamchatka. The aim of the work was to study the morphology and structure of cinder cones and lava flows and the compositions ...
-
(1996)The intensity and spectral characteristics of speleothem luminescence are investigated for signs of any potential palaeoenvironmental signals. Luminescence in speleothems has been demonstrated to have an organic acid source, ...
-
(2004)Four sets of δ18O and δ13C curves were derived from Late Glacial to mid-Holocene spring and lacustrine carbonates from Belarus. Stratigraphic division was carried out by palynological studies and 14C-dating. It was revealed ...
-
(2000)Representative materials from sea drilling sites with complete geological records and detailed geological-geomorphological analysis of sediments in the Primor'e coast and shelf (lithological and paleontological methods ...
-
(2001)Seismic activity in southern Sakhalin is related to zones of submeridionally striking faults (upthrow and normal faults) separating ridges and intermountain depressions, and transorogenic faults of the NW (sinistral ...
-
(1997)Down-core trends for extents of iron sulfidation in upper Holocene microlaminated deposits of the Black Sea abyssal plain imply that most of the pyrite in these sediments is formed in the sulfidic water column and/or very ...
-
(2002)A brief review is presented of the progress, to date, in constructing a long, continuous ring-width chronology from living and subfossil Siberian larch (Larix gmelinii) in the eastern part of the Taimyr peninsula. A near ...
-
(2004)Testate amoebae (Protozoa: Testacea) were studied in the Late Quaternary permafrost deposits in the Siberian Arctic (Bykovsky Peninsula of the Laptev Sea coast, 71j40V– 71j80VN and 129j – 129j30VE). The Testacea associations ...
-
(2003)The Arctic rift system includes the Mid-Arctic Gakkel Ridge, the Laptev Sea continental margin and the Moma rift. The Gakkel Ridge is the world''s slowest spreading mid-ocean ridge with spreading rates ranging from 1.2 ...
-
(2001)By correlating the pronounced interstadial-type diatom peak with MIS 3, the high-resolution and well-dated record BDP-93-2 from the Selenga Delta area of Lake Baikal complements the classical long paleoclimatic records ...
-
(2003)The paleoclimate since 14 kyr BP (14C age) was reconstructed based on a 16.22-m-long sediment core collected from Lake Yanhaizi, a saline lake located near the northern limit of the East Asian summer monsoon in Inner ...
