(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)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 ...
-
(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)About 50000 P and S arrival times and 25000 values of t* recorded at seismic arrays operated in the Central Andes between 20°S and 25°S in the time period from 1994 to 1997 have been used for locating more than 1500 deep ...
-
(2006)In the Central Iberian Zone there are several large thermal domes in which small bodies of ultramafic, mafic and intermediate rocks appear intimately associated with crustal granites and migmatites. The closest spatial ...
-
(2006)Psittacosaurus sibiricus from the Aptian-Albian Ilek Formation at Shestakovo, Kemerovo Province, West Siberia, is represented by two almost complete adult skeletons, several associated groups of bones and numerous isolated ...
-
(2006)Archaean banded iron formation (BIF) of the Voronezh Crystalline Massif (VCM) contains coexisting clino- and orthopyroxenes with exsolution textures. The pyroxene in the VCM BIF is found in two generations, with only the ...
-
(2006)Rb-Sr data were obtained for different Lower Cambrian rocks from boreholes Bel'sk and Zhigalovo drilled in the Irkutsk amphitheater. Shales in the lower part and insoluble residue of marls throughout the entire (up to 2 ...
-
(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)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)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 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)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 ...
