(2004)The phase (P) and amplitude (A) anomalies in subionospheric LF signal (40 kHz) along the path Japan–Kamchatka of 2300 km have been studied for the data observed by means of a digital OminiPAL receiver for 2 years. The ...
-
(2004)Chemical and isotopic compositions (Sr isotopic ratio, major elements, trace elements, rare earth elements, total carbon, nitrogen, and sulfur contents) of rock samples collected from middle Miocene to early Pliocene ...
-
(2002)Bryozoa (23 species) from many boreholes in the Belarussian part of the Podlasic-Brest Depression and some adjacent areas of the East European Platform arc described. Only bryozoa from the orders Cystoporida (suborder ...
-
(2003)In order to test different hypotheses concerning the Paleozoic evolution of the Ural–Mongol belt (UMB) and the amalgamation of Eurasia, we studied Middle Devonian basalts from two localities (11 sites) and Lower Silurian ...
-
(2001)The Paleozoic fold-and-thrust belt, confined between the European, Siberian, Tarim, and North China Precambrian continents, results from a complex evolution of the Paleo-Asian Ocean. At the end of the Ordovician, the ...
-
(2002)A small brachiopod fauna is described from the lower part of the Xiujimqinqi Formation of the Xiujimqinqi area in central-east Inner Mongolia, northeast China. The age of this fauna is regarded as Wordian (Middle Guadalupian, ...
-
(2003)Materials on small mammals collected during last years enable discrimination of an autonomous Uryv faunal assemblage in the Pliocene succession of mammal communities of the Russian Plain. Data on taphonomy and compositional ...
-
(2000)The paper considers the structure, lithology, and facies characteristics of the Yurmatin and Serafimovka groups of the Bashkir meganticlinorium and Volga–Urals region. The analyzed distribution schemes of facies associations ...

(2003)In thе lаtе middlе tо еarliеst latе Еoсеnе, a vast dysохiс to anoхiс bаsin еxtеndеd from thе Сrimеа in thе Wеst through thе northеrn Cauсasus to thе Aгal Sеа in thе Еast' and a hugе amount оf organiс сarbon was dеpositеd ...
-
(2000)Radiolarians were found in the upper Anisian, upper Ladinian, and lower Carnian deposits of the Omolon massif. Their assemblages are less diverse than the coeval Mediterranean assemblages but very similar to the Middle ...
-
(2002)The UV edge in the electronic absorption spectra of minerals, in many cases influencing their colour, is generally interpreted as the low-energy wing of very strong UV bands caused by ligand–metal charge transfer (CT) ...
-
(1991)The problem of activation energy calculations of lead loss from zircon and the determination of the lead diffusion coefficient in zircon based on the kinetics of diffusion is dealt with. The experimental technique for the ...
-
(1988)We have developed a migration method for scalar components of the electromagnetic field that can be used to reconstruct the locations of geoelectric nonuniformities from the measured components of the magnetic or electric ...
-
(1988)We attempted a new approach to evaluating the migrational ability of minerals, based on their settling rates, one of the fundamental values governing the placer-forming properties of minerals. Since we were interested in ...
-
(2004)The abundances of the mildly incompatible elements Al, Cr, V, Sc and Yb in more than 1700 mantle peridotite bulk rock analyses are interpreted in the light of a fractional melting model based on experimentally measured ...
-
(2004)Diatom analysis of two submarine cores off eastern Hokkaido Island, northern Japan, provides insights into the Holocene palaeoenvironmental history of the southwestern Okhotsk Sea. Diatom flora was mainly composed of ...
-
(2001)Central-type endogenic structures (CTS) are a class of injective deformations of crustal and mantle origin, which control distribution of deposits and areas of accumulation of different-type mineral resources (metal ores, ...
-
(1996)The Inagli complex, one ot several Mesozoic intrusive complexes of the Aldan Shield (Siberian Platform), exhibits a concentric structure comprising several alkaline ultramafic rock-types. A central dunite body is surrounded ...
-
(1998)A comprehensive study of the petrography, cathodoluminescence (CL), rare earth element (REE) abundances, and magnesium and silicon isotopic compositions of enstatite, the major mineral in unequilibrated enstatite chondrites ...
