(1995)Volcanic and intrusive rocks of the Chegem caldera and the nearby Eldjurta (Eldzhurtinskiy) Granite record a late Pliocene episode of silicic magmatism in the north-central Caucasus Mountains. Surface exposures, created ...
-
(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 ...
-
(2004)The thorough study of main Neogene sections in scarps of the Irtysh River valley north of Omsk allows substantial corrections in stratigraphy of the West Siberian Plain. We have established the Isakovka assemblage, marking ...
-
(2001)A palaeomagnetic and rock magnetic study was carried out on samples of the Djavakheti, Khrami and Kazbeki regions in Georgia. Samples were taken from 44 localities from 247 subaerial lava flows and from 3 lacustrine ...
-
(2006)Surface and subsurface geological features of the Himalayan - Tibetan orogenic system may be explained by three sets of processes: those related to plate convergence, those related to the gravitational spreading of a fluid ...
-
(2006)New geochemical data for Pleistocene magmatic rocks from the Surigao peninsula, eastern Mindanao, the Philippines, demonstrate typical adakitic traits, including elevation of Sr/Y and depletion of the heavy rare earth ...
-
(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 ...
-
(2006)To date the formation of ruby deposits and link it to the regional metamorphism associated with Tertiary Himalayan orogenesis, 40Ar-39Ar stepwise heating experiments were performed on single grains of phlogopite syngenetic ...
-
(2001)The morphology of the gravity field and the distribution of Pliocene ignimbrites were analyzed to locate Late Neogene calderas which had been covered by younger volcanic formations.
-
(2001)Carbon isotopic composition was studied in oils and hydrocarbon gases from different oil and gas fields and reservoirs hosted in the Upper Cretaceous to Upper Pliocene sequences of the South Caspian mega-depression. It was ...
-
(2006)In 2002, high-resolution sidescan sonar images of a mound area at the SW Rockall Trough margin were recorded with the TOBI deep towed sidescan sonar. Processed TOBI images with a pixel resolution of 6 m provide a unique ...
-
(2002)Carnivores of the Khapry faunal assemblage that is commonly considered as an analogue of the middle Villafranchian West European fauna (Late Pliocene, Zone MN17) were revised. Members of nine Carnivora genera are described ...
-
(2000)The mineral assemblage of Pliocene - Pleistocene bottom sediments of Lake Baikal, exposed by the deep-sea BDP-96-2 (Baikal Drilling Project) has been studied by the methods of XRD and IR spectroscopy. Complex XRD patterns ...
-
(1999)A palynological analysis of the Baikal sediments from a 200 m deep borehole permitted tracing continuous climatic and vegetation changes in the Baikal region for the last 5 Ma (from the Early Pliocene). The sediment age ...
-
(1988)As far as the climatic history of the Late Cenozoic is concerned, the second half of the Pliocene is especially interesting because during that comparatively short time interval there were many important paleogeographic ...
-
(2006)Structural evolution of the Kamchatka-Aleutian junction area in late Mesozoic and Tertiary was generally controlled by (1) the processes of subduction in Kronotskiy and Proto-Kamchatka subduction zones and (2) collision ...
-
(2001)The deep structure of the Eurasia-Pacific transition zone was investigated under the Geotraverse International Project along the deep sections of the tectonosphere, including the lithosphere and the asthenosphere, based ...
-
DEPOSITIONAL AND TECTONIC FRAMEWORK OF THE RIFT BASINS OF LAKE BAIKAL FROM MULTICHANNEL SEISMIC DATA (1992)Recent multichannel seismic reflection data from Lake Baikal, located in a large, active, continental rift in central Asia, image three major stratigraphic units totaling 3.5 to 7.5 km thick in four subbasins. A major ...
-
(2001)The synthesis of petrological, geochemical, and isotopic data on granitoids from the Tyrnyauz area (El'dzhurtinskii Massif) and the critical analysis of the current petrologic-tectonic systematics of granitoids indicates ...
