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. ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(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 ...
