(2004)The reconstruction of the Late Weichselian glacial limits is based on geomorphological evidence combined with geological data. The maximum extension of the Last Glaciation has been established in Southeastern Lithuania. ...
-
(2001)Opening mode of the Japan Sea is studied from the viewpoint of geologic structure around the western marginal fault zone of the back-arc basin. Latest reflection seismic survey in the Fukue Basin, located at the western ...
-
(2001)The potential of in situ cosmogenic 14C (in situ 14C) for surficial process studies is widely recognized, yet a reliable means of isolating it has proved difficult to develop. We present here a new method for extracting ...
-
(2004)A new convenient combinatorial method is developed here to derive the invariant points in multisystem closed nets - the absent phase substitution (APS) method. It substantially simplifies the derivation of the closed nets ...
-
(2001)A refined pedostratigraphic scheme in the western Black sea region is proposed on the basis of paleopedological reconstructions coupled with magnetic susceptibility, and other rock magnetic parameters, and Mössbauer ...
-
(1994)Rock-magnetic measurements of sediment cores from the Academician Ridge region of Lake Baikal, Siberia show variations related to Late Quaternary climate change. Based upon the well-dated last glacial-interglacial transition, ...
-
(2002)We describe an active right-lateral strike-slip fault zone along the southern margin of the Japan Sea, named the Southern Japan Sea Fault Zone (SJSFZ). Onshore segments of the fault zone are delineated on the basis of ...
-
(2000)Maps of faults (geologically defined source zones) may portray seismic hazards in a wide range of completeness depending on which types of faults are shown. Three fault terms - active, capable, and potential - are used in ...
-
(1995)The sorption of Co(II)EDTA2- (where EDTA is ethylenediaminetetracetic acid) was investigated on goethite and on eight sand-textured Quaternary and Pliocene fluvial sediments. Dual-label tracer techniques were used to follow ...
-
(1989)This article presents the results of the first attempt in the USSR to use the process of racemization of amino acids for the geochronometry of Quaternary deposits. This research tool has been used elsewhere for more than ...
-
(1999)High precision measurements of Sr/Ca in planktonic foraminifera for the last 150 ka reveal Sr/Ca variations of up to 12% on glacial/interglacial time scales. Although records showing the largest variations appear to be ...
-
(2002)The Marmara Sea is situated between the world's largest permanently anoxic basin, the Black Sea, and an enclosed marginal sea, the Aegean Sea, which experienced quasi-periodic sapropel deposition since Miocene time. It is ...
-
(1997)About 10,000 years ago, at the Pleistocene-Holocene border, some important events occurred: the glaciation stopped abruptly; the sea level elevated, and quick (for 20-50 years) climatic and ecological changes took place, ...
-
(1998)The structure of the avacha Depression, covered by a thick sequence of volcanic rocks, volcano-sedimentary deposits, and loose Quaternary sediments of varying origins, was reconstructed using the results of a geological ...
-
(2004)An 8-m continuous sediment core, approximately 250-ky-old at the bottom, from Academician Ridge in Lake Baikal, has been analyzed for the stable isotopes of carbon, nitrogen and sulfur, in order to study the paleoclimatic ...
-
(2004)Among materials of the OJSC Lukoil obtained in the northern Caspian region, there are cores samples recovered from the depth of 7 to 37 m below bottom, piston cores, and high-resolution seismic profiles. These materials ...
-
(1999)Ti-biotite megacrysts, glimmerites, and intergrowths of biotite, clinopyroxene, and ilmenite megacrysts were found in Quaternary basanites and Miocene picrobasaltic tuff of the Vitim Plateau. The TiO2 content in the micas ...
-
(2004)Previous studies concluded that the Bosphorus Strait was formed during the Quaternary by fluvial incision of a valley between the Black Sea, to the north, and the Marmara Sea in the south. Hitherto, however, few details ...
-
(1996)Carbonates of mantle origin have been found in xenoliths from Quaternary basaltic volcanoes in NW Spitsbergen. The carbonates range from dolomite to Mg-bearing calcite and have high Mg-numbers [Mg/(Mg+Fe)=(0.92–0.99)]. In ...
-
(1989)We chose for investigaton the Koshabulak tectonic structure, within the Sultan-Sandzhar swell, which is one of the group of Pitnyak tectonic uplifts of the Bukhara Bench, which were formed during Hercynian time and continue ...
