-
(2006)Most titanomagnetite in the Khibina alkaline igneous complex, sampled through 500 m of a vertical cross-section, is represented by Ti-rich varieties. The ulvöspinel component is most commonly around 55 mol%, rarely reaching ...
-
(2006)In previous communications based on the study of sulfur and strontium, we showed that Lower Cambrian rocks of the Irkutsk Amphitheater underwent a significant epigenetic transformation. All postsedimentary alterations of ...
-
(2006)The P and S seismic anomalies in the upper mantle beneath the Pamir-Hindukush collision zone and surrounding areas are investigated using more than 4 × 105 traveltimes from 5775 events located in the study region, recorded ...
-
(2006)Some Mg-rich garnet pyroxenites from the Mir kimberlite, Siberia, have garnets containing oriented arrays of diopside, rutile + diopside or rutile + Mg-rich ilmenite inclusions. Present mineral compositions require storing ...
-
(2006)The occurrence and distribution of minerals, and major and trace elements of the coal #6-1 from the Cretaceous Wulantuga high-germanium coal deposit in Shengli coal field, Inner Mongolia are investigated. The major mineral ...
-
(2006)The composition, structure, and geochemical properties of the thickest, relatively deep-water Lower Miocene sediments developed in western Ciscaucasia are considered. Of particular interest are materials from the Kuban ...
-
(2006)Monitoring of geophysical conditions of marine sedimentary basins is necessary for predicting seismic events and for adaptation of geothermal technologies for seismically active (as a rule) sea bottom geothermal areas. ...
-
(2006)New results of geomorphological, seismoacoustic, and lithological investigations on the upper continental slope off the Arkhipo-Osipovka Settlement are presented. Here, a large submarine slump was discovered by seismic ...
-
(2006)Melt and fluid inclusions in minerals have been studied and physicochemical parameters of magmatic processes and hydrothermal systems estimated at the Yaman-Kasy copper massive sulfide deposit in the southern Urals. It was ...
-
(2006)Based on the study of several different-age shallow-water carbonate sediments from different regions, it is established that cyclothems formed in basins of arid and humid climatic zones differ in their composition and ...
-
(2006)Geochemical and radiogenic age data are incompatible with the idea that the gneiss-complexes of the East Uralian Zone are microcontinental blocks that collided with the Magnitogorsk island arc during the Uralian orogeny. ...
-
(2006)Crystallization of borosilicate glasses, used now for solidification of liquid nuclear high-level wastes (HLW), is accompanied by the formation of silicates with the apatite-type structure and high contents of actinides ...
-
(2006)Paleomagnetic, rock magnetic, and petrophysical results are presented for impactites and target rocks from the Lake Jänisjärvi impact structure, Russian Karelia. The impactites (tagamites, suevites, and lithic breccias) ...
-
(2006)The mineralogy and PT formation conditions of the Dzhimidon Pb-Zn deposit in the Sadon ore district are considered. The deposit is localized in metamorphic rocks of the Buron Formation, which pertain to the pre-Jurassic ...
-
(2006)The fluorine-beryllium deposits of the Vitim Highland are represented by two mineral types: feld-spar-fluorite-phenakite-bertrandite and thorite-fluorite-phenakite. Their localization is controlled by fault zones of various ...
-
(2006)High-pressure (HP) and ultra-high pressure (UHP) terranes are excellent natural laboratories to study subduction-zone processes. In this paper we give a brief theoretical background and we review experimental data and ...
-
(2006)We develop a parametric inversion algorithm to determine simultaneously the horizontal and vertical resistivities of both the formation and invasion zones, invasion radius, bed boundary upper location and thickness, and ...
-
(2006)Magmatic explosive eruptions are influenced by mass transfer processes of gas diffusion into bubbles caused by decompression. Melnik and Sparks [Melnik, O.E., Sparks, R.S.J. 2002, Modelling of conduit flow dynamic during ...
-
(2006)Filtration-capacity properties of terrigenous reservoir rocks significantly depend on catagenetic transformations of clay minerals. Results of our research revealed the authigenic nature and formation stages of kaolinite ...
-
(2006)Data on fluid inclusions and stable isotope compositions (O, H, C, and S) in minerals have been summarized for large- and middle-scale mesothermal gold deposits (Nezhdaninsk, Berezovsk, Kochkar', Svetlinsk, Darasun, and ...
