-
(2002)Current knowledge of the Earth's gravity field and its geoid, as derived from various observing techniques and sources, is incomplete. Within a reasonable time, substantial improvement can only come by exploiting new ...
-
(2001)The paper presents the results of ten-years deep drilling on Baikal (joint Russian-American-Japanese Baikal Drilling Project). During the project run, five sets of boreholes were drilled in various geomorphic structures ...
-
(2001)The fluid inclusions preserved in high and ultrahigh pressure rocks provide direct information on the compositions of fluid phases evolved during subduction zone metamorphism, and on fluid–rock interactions occurring in ...
-
(2003)The role of geodynamics and mantle plumes in the formation of the Central Asian Fold Belt is discussed. The isotopic geochemical study demonstrates that the mantle plumes were derived from moderately depleted and enriched ...
-
(2001)This paper addresses the problems of ore metal mobilization and concentration and volatile component behavior in the Earth's mantle. Diamond crystallization and the formation of chromitite bodies upon interstitial melt ...
-
(2004)We present partial melting experiments that constrain the near solidus phase relations of carbonated eclogite from 2 to 8.5 GPa. The starting material was prepared by adding 5 wt.% CO2 in the form of a mixture of Fe–Mg–Ca–Na–K ...
-
(2003)Abyssal peridotites collected along the highly oblique-spreading Lena Trough north of Greenland and Spitsbergen have mineral compositions that are similar to residual abyssal peridotites, except for high sodium concentrations ...
-
(1983)The structure of the crust and the Moho surface along a profile intersecting the Mirny kimberlite field is considered. Revealed heterogeneous structure of the crust and upper mantle. It is assumed that the selected seismic ...
-
(2002)We investigate the deep structure and mechanical behavior of the lithosphere beneath the Hangai–Hövsgöl region, central Mongolia, Asia, in order to explain the origin and support of large-scale doming in this deforming ...
-
(1989)A key feature in present tectonic schemes for central Asia is the Dzhida structure of the early Caledonides. Its origin is explained by theories on both mobile, shifting and permanent, fixed continents, which, therefore, ...
-
(1989)The junction of the East European craton and the Sythian-Turanian platform runs under the northern Caspian Sea, as does the continuation of their major structures. However, because extremely little is known about the geology ...
-
(1991)From joint analysis of compressional and shear waves generated by shots and by local earthquakes, new specific features are established for the model of the Earth's crust and upper mantle in the Baikal rift zone. Poisson ...
-
(2001)The paper deals with the issues pertaining to localisation of metallogenic targets of the ore district and ore field rank on the basis of the medio-scale geologic-geophysical data using as an example the Bekchi-U1 gold ...
-
(2003)The deep structure of the West Siberian Plate and its folded surroundings has been imaged in geoscience transects based on geophysical surveys (DSS, CDP profiling, seismic tomography, gravity, magnetic, geothermal, MT, and ...
-
(2002)The EUROBRIDGE'96 seismic refraction and wide-angle reflection profile in Belarus crosses the 2.0–1.9 Ga Palaeoproterozoic Central Belarus belt (CB) subdivided by NE-trending Minsk Fault into the northwestern (NWCB) and ...
-
(2004)The structure ofthe Earth's crust beneath the Sukhoi Log deposit is considered in the context of the deposit origin. A combination of geological, gravimetric, and geoelectric data helped us to distinguish three layers ...
-
(2001)The deep structure of the Eurasia-Pacific transition zone was investigated under the Geotraverse International Project along the deep sections of the tectonosphere, including the lithosphere and the asthenosphere, based ...
-
(1992)Data on the geophysics and geology of the jointing zones separating the areas of Archean and early Proterozoic consolidation of the Ukrainian and Baltic shields were compared. It was discovered that the deep structure and ...
-
(2002)The Black Sea is considered to be a Mesozoic–Early Cenozoic marginal basin related to the north-dipping subduction of Tethys beneath Europe. However deformation of this basin during the successive Eocene to Neogene collisions ...
