-
(2006)The paper presents a detailed description of the geological structure, mineralogy, and chemical composition of the Archean weathering profile of granitoids in the Baltic Shield. Based on model calculations, the primary ...
-
(2006)A new variety of matrices based on synthetic phases whose structure is close to that of murataite (a natural mineral) is proposed for immobilization of nuclear wastes. Murataite is Na, Ca, REE, Zn, and Nb titanate with a ...
-
(2006)Geochemical properties of ore-bearing horizons composed of alluvial aluminosilicate terrigenous rocks have been compared at young and ancient hydrogenic uranium deposits. It has been shown that the lithological setting at ...
-
THE PERMIAN OF THE TRANSBAIKAL REGION, EASTERN RUSSIA: BIOSTRATIGRAPHY, CORRELATION AND BIOGEOGRAPHY (2006)Permian deposits in the Transbaikal region within the Mongol-Okhotsk belt and adjacent areas have been studied. The characteristics of the Permian marine and continental formations are documented, and our present understanding ...
-
(2006)Microrhythmic layering is locally developed in agpaitic arfvedsonite lujavrite from the Ilímaussaq alkaline complex, South Greenland. Three-15-cm-thick laminated dark layers alternate with 1-10-cm-thick, light-coloured ...
-
(2006)In a previous paper, Khokhlov et al. introduced a method to test the compatibility of so-called 'giant Gaussian process' (GGP) statistical models of the palaeomagnetic field against any palaeosecular variation database. ...
-
(2006)The cavitation and cavitation-ablation mechanisms of formation of mineral nano-and microspherules in hydrothermal fluids are considered. The formation conditions of nano-and microspherules were studied with regard to the ...
-
(2006)Variation of geochemical modules and indices in mudstones from the Upper Vendian Kairovo and Shkapovo groups of the Shkapovo-Shikhan Basin provides the comprehensive information on changes in maturity of the fine ...
-
(2006)We apply a limited-memory quasi-Newton (QN) method to the 1D magnetotelluric (MT) inverse problem. Using this method we invert a realistic synthetic MT impedance data set calculated for a layered earth model. The calculation ...
-
(2006)We present the results of the infrared (IR) microscopic study of the anomalous carbonaceous chondrites Dhofar (Dho) 225 and Dhofar 735 in comparison to typical CM2 chondrites Cold Bokkeveld, Murray, and Mighei. The Fourier ...
-
(2006)The Omgon Range of Western Kamchatka contains a mid to Upper Cretaceous sequence of flysch with tectonic inclusions of Jurassic-Cretaceous oceanic rocks inferred to have been imbricated together in an accretionary prism. ...
-
(2006)Zeolites are represented by clinoptilolite (from 15-20 to 30-32%) in Paleogene rocks of the southern Russian Platform. Zeolite-bearing complexes formed under coastal-marine conditions of the platform type. Clinoptilolite, ...
-
(2006)Electromagnetic fluctuations in the ocean have external sources like ionospheric-magnetospheric current systems, and purely internal oceanic sources associated with interaction between water velocity fields and the geomagnetic ...
-
(2006)Analysis of vibroseis data shows that harmonic distortion in the ground-force signal may exceed the primary distortions in the hydraulic system. This can be explained by the baseplate-ground contact nonlinearity created ...
-
(2006)In year 2000, a ship-based expedition carried out a ca. 500-km-long geophysical profile ('Arctic-2000') across the Mendeleev Ridge at 82°N, from the Podvodnikov Basin to the Mendeleev Basin. A crustal-scale refraction ...
-
(2006)Strontium and and carbon isotopic data from amphibolite-facies marbles of the Falkenes formation, Sørøy succession (structurally upper Kalak Nappe Complex) in West Finnmark, northern Norway, indicate that the marbles were ...
-
(2006)Numerical models are presented that simulate several active tectonic processes. These models include a continent that is thermally and mechanically coupled with viscous mantle flow. The assumption of rigid continents allows ...
-
(2006)A new method is proposed for calculating equilibria in mixed multicomponent systems H2O-nonpolar gas at high temperatures and pressures. The method is based on calculation of electrostatic interactions between a solute ...
-
(2006)The distribution of noble metals has been studied in ores and sulfide concentrates from the Gai, Uchaly, Uzel'ga, Aleksandrinsky, Degtyarsk, and Saf'yanovka deposits. The ores, technological products, and hand-picked ...
-
(2006)By analogy with other metallogenic belts of the Circum-Pacific ring, the metallogenic belts in the Northeast of Russia are promising for discovery of large and superlarge porphyry-type Au-Cu-Mo deposits. The spatial ...
