-
(2003)Inherited saprolite stores and continued weathering in Quaternary time juxtapose abundant clay and fresh rock in tropical landscapes. This influences sediment fluxes and affects the interpretation of sediment sequences ...
-
(2004)The Ulleung Interplain Gap (UIG) is a deep (2300–2700 m) passage which has served as a conduit for deep-water circulation between the Ulleung and Japan basins. A detailed analysis of Chirp (2–7 kHz) subbottom profiles (ca. ...
-
(2002)Slip rates across active faults and folds show that late Quaternary faulting is distributed across the central Tien Shan, not concentrated at its margins. Nearly every intermontane basin contains Neogene and Quaternary ...
-
(1999)Ice-sheet reconstructions for the last glacial maximum in northern Eurasia range from nearly complete coverage by a contiguous marine-based ice sheet to large unglaciated areas. Stratigraphic records from Yamal Peninsula, ...
-
(1999)New sites of mineralized microfossils, seven in cherts and one in phosphorite of the Upper Riphean Valyukhta Formation-of the Baikal-Patom Highland, are discovered at the Alekan River (the Malaya Chuya River basin). The ...
-
(2001)The age of ophiolite plagiogranites from the Khan-Taishiri ophiolite complex, western Mongolia, was determined by the U-Pb zircon method as 568.1 ± 4.0 Ma. This complex is a rare fragment of the ancient Central Asian blocks ...
-
LATE VENDIAN POTASSIC VOLCANIC ROCKS OF THE OLENEK HIGHLANDS ON THE NORTHEAST OF THE SIBERIAN CRATON (1989)The authors investigated a rock complex in the northern part of the Olenek Highlands on the Siberian craton, where it lies in the Khorbusuonka, Erkeket, and Kersyuke river basins. These potassic volcanics are found over ...
-
(2003)Six species of Calamopityales (Lyginopteridophyta) are reported for the first time from the Upper Viscan sandy-silty deposits of Central Russia (vicinity of the town of Borovichi). Among these species, Sphenopteridium ...
-
(2004)Five lyginopteridalean species of the genera Rhodeopteridium (Zimmermann) Purkynová and Sphenopteris Brongniart and one species of Rhynchogonium Heer (Medullosales=Trigonocarpales) are reported from the vicinity of the ...
-
(2002)Results from a numerical ice-sheet model were matched with geological evidence detailing the extent and timing of the Late Weichselian ice sheet in the Eurasian Arctic, through simple adjustments in the model’s environmental ...
-
(2003)Data from ice cores suggest that Late-glacial and early Holocene atmospheric CO2 variations were rather conservative, the most important change being a gradual Younger Dryas increase. By contrast, palaeo-CO2 records based ...
-
(2004)The aim of the study is to record the occurrence of sediment deformation structures in one of the tectonically most active areas on the globe, the Tien Shan range in Central Asia and to examine the significance of the ...
-
(2004)A comparison of the Black and White Seas, which differ in their tectonic, glacial and climatic history but which share a strong dependence upon limited water exchange with the world ocean, represents an opportunity for the ...
-
(2001)Very low to zero shallow dip angles are observed at several moderately young subduction zones with an active trenchward moving overriding plate. We have investigated the effects of latent heat for this situation, where ...
-
(1987)The Chordi Deposit is located in the Oni district, Georgia, among Middle Jurassic volcano-sedimentary rocks on the 'andesite line' of the Gagra-Dzhava structural-metallogenic zone. It consists of a series of steeply dipping ...
-
(2000)The proposed study is based upon the joint use of pairs of seismic rays refracted and reflected from the Earth's surface (scheme RR-R). This approach makes possible studies of the upper mantle in "mute" seismic regions ...
-
(1990)A method allowing detailed mapping of lateral inhomogeneities of the upper mantle in mobile regions of various types has recently been developed. The method is based on the analysis of the absorption patterns of short-period ...
-
(2001)When a new sedimentary unit is deposited over a region with significant differences in the thickness of the pre-existing sedimentary cover, the thickness of the new unit may express lateral differences in sediment compaction ...
-
(2002)Lateral motion of material relative to the regional thermal and kinematic frameworks is important in the interpretation of thermochronology in convergent orogens. Although cooling ages in denuded settings are commonly ...
