-
(2006)The paper presents results of the study of assemblages of clastic heavy minerals and geochemical features of some assemblages in several Permian-Mesozoic cherty and siliceous-clayey sequences of Sikhote Alin. They are ...
-
(2006)Significant differences between faunal and floral associations existing in different paleogeographic realms in the Kungurian-Late Permian interval make it difficult to correlate the Permian deposits of the world. Resolving ...
-
(2006)As indicated by mineralogical, geochemical, and structural-textural data, the base-metal skarn ore at the Partizansky deposit was formed during two stages (base-metal skarn and silver-sulfosalt), which were separated by ...
-
MICROINCLUSIONS IN DIAMONDS OF OCTAHEDRAL HABIT FROM KIMBERLITES OF SHANDONG PROVINCE, EASTERN CHINA (2006)Microinclusions in octahedral diamond crystals from kimberlites of Shandong Province, eastern China, have been studied with analytical scanning electron microscopy. Native iron, tungsten, and lead; Fe-Cr intermetallic ...
-
(2006)The Model Parameter Estimation Experiment (MOPEX) is an international project aimed at developing enhanced techniques for the a priori estimation of parameters in hydrologic models and in land surface parameterization ...
-
(2006)Compositions of parental and primary melts are modelled for olivine-hosted melt inclusions in three, Palaeogene, proto-Iceland plume picrite samples from East Greenland. The samples represent three stages in the magmatic ...
-
(2006)Specific features of the mineral composition of economically promising titanium-zirconium placers in Russia are analyzed. Generalization of the data made it possible to classify titanium-zirconium deposits with respect to ...
-
(2006)The Kurile Basin in the Okhotsk Sea, northwestern Pacific, is a back-arc basin located west of the Kurile Island Arc. Cenozoic sedimentation on the Kurile Basin northern slope and on the Academy of Science Rise was studied ...
-
(2006)The paper describes olivine melilitites at Oldoinyo Lengai, Tanzania, and from tuff cones from the Tanzanian rift valley in the vicinity of Oldoinyo Lengai. Oldoinyo Lengai is the only active carbonatite volcano and is ...
-
(2006)This paper summarizes the spatial distribution, stratigraphical divisions and biostratigraphical zonation schemes of Permian marine deposits in Mongolia. Where appropriate, correlations of the various Permian marine ...
-
(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 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. ...
