(1996)Continental records of Plio-Pleistocene climatic fluctuations are often confined to fragmentary, localized basins, and not easily dated. One exception is the Confidence Hills of Southern Death Valley. In this study, we ...
-
(1998)The paper considers the first results of investigation of the cores obtained by drilling in Lake Baikal on the top of the underwater Akademichesky Ridge in 1996. Two boreholes, one to a depth of 300 m, and the other to a ...
-
(2001)Two boreholes, BDP-96-1 (200 m thick) and BDP-96-2 (100 m thick), drilled at the top of the underwater Akademichesky Ridge at 53°41′48″N and 108°21′06″, gave two parallel cores which were dated paleomagnetically. The ...
-
(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 ...
-
(1995)Dynamical instabilities in the glaciation and deglaciation of the ice sheets can be triggered by pulsations of the rate of change of the orbital and rotational parameters. The purpose of this paper is to demonstrate that ...
-
(1996)The abundance and isotopic composition of total and pyrite sulphur have been determined in a core in the central Black Sea. Pyrite varies in concentration from roughly 2 wt% in the sapropel (Unit 2), to 0.8 wt% in the ...
-
ACTIVE VOLCANOES OF KAMCHATKA: SPATIAL AND TEMPORAL DYNAMICS OF ERUPTIVE INTENSITY AND PRODUCTIVITY (2000)The total volumes of volcanic rocks and average annual productivities of active volcanoes were calculated for all volcanic zones of Kamchatka for the mid-Pleistocene, Late Pleistocene, and Holocene epochs. Average values ...
-
(2004)The SedFlux model is modified to more realistically simulate the distributions of seafloor geotechnical parameters during the growth of a seismically active continental margin. Alternative methods are provided for the ...
-
AGES OF CALDERAS, LARGE EXPLOSIVE CRATERS AND ACTIVE VOLCANOES IN THE KURIL-KAMCHATKA REGION, RUSSIA (1995)The ages of most of calderas, large explosive craters and active volcanoes in the Kuril-Kamchatka region have been determined by extensive geological, geomorphological, tephrochronological and isotopic geochronological ...
-
(2001)Long continuous lacustrine sequences constitute on the continent a precious tool for coupling the long term continental environmental changes with deep sea and ice core records, using the 'count from the top' method. ...
-
(2002)Although shelf-edge deltas are well-imaged seismic features of Holocene and Pleistocene shelf margins, documented outcrop analogues of these important sand-prone reservoirs are rare. The facies and stratigraphic architecture ...
-
(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, ...
-
(2005)Geomorphologic, marine geological, and paleoclimatic evidence, along with modeling results, indicate that, during the Late Pleistocene, the Sea of Okhotsk was glaciated by a "back-arc" marine ice-sheet, which was a continuous ...
-
(1989)The main task of paleoclimatology is the definition of the trend of climatic change and the identification of the events that occurred in the Earth's history. The Pleistocene, especially the late Pleistocene, was an epoch ...
-
(2001)The difference between the climates of the Bering Land Bridge and Asiatic (western) Beringia 18–20 ka ago is discussed. The climatic reconstructions of the Bering Land Bridge and western Beringia are based upon two methods. ...
-
(2004)During the middle to late Pleistocene glacial lowstands, when the Japan Sea was almost isolated geographically, low-salinity surface water and anoxic deep water were formed. Pliocene to early Pleistocene buccinid gastropods ...
-
(1988)Geologic, geomorphic and tephrochronologic data and the results of C14 dating indicate that in Kamchatka and the Kurile Islands in the last 40,000 to 45,000 years there were at least 50 very powerful explosive eruptions ...
-
(2004)Two gravity cores (1.1 and 2.2 m long) of deep-water bottom sediments from Lake Khubsugul (Mongolia) were studied. The Holocene, biogenic silica and organic matter-rich part of the first core was subjected to AMS radiocarbon ...
-
(2004)Data from mineral magnetics, heavy mineral and quartz grain micromorphology analysis are compared, from early Pleistocene glacial sediments in the River Don palaeo-valley (central part of the Russian Plain). The aim was ...
-
(2001)The Pleistocene deposits on the plains regions of Ukraine are subaerial and subaqueous formations of diverse types. Loesses and fossil soils represent 16 climatic stages (8 warm and 8 cold) of the Pleistocene and environmental ...
