(2003)This paper presents a new decoupled form of the formula for common-shot or common-receiver amplitude-preserving elastic prestack depth migration (PreSDM), which can be used for estimating angle-dependent elastic reflection ...
-
(2003)The simulation of sedimentary basins aims at reconstructing its historical evolution in order to provide quantitative predictions about phenomena leading to hydrocarbon accumulations. The kernel of this simulation is the ...
-
(2003)A state-space representation of the transfer function-noise (TFN) model allows the choice of a modeling (input) interval that is smaller than the measuring interval of the output variable. Since in geohydrological applications ...
-
(2003)During the Hauterivian three important phases of platform drowning, phosphogenesis and mesotrophic carbonate deposition along the northern margin of the Tethys are not mirrored by positive δ[13]Ccarb excursions such as ...
-
(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 ...
-
(2020)The description of rocks is one of the most time-consuming tasks in the everyday work of a geologist, especially when very accurate description is required. We here present a method that reduces the time needed ...
-
(PANGAEA, 1975-03-15)
-
(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 ...
-
(PANGAEA, 1986-03-20)
-
(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 ...
-
(Федеральное государственное бюджетное образовательное учреждение высшего образования «Санкт-Петербургский горный университет», 2020)We investigated the deep structure of the lithosphere and the geodynamic conditions of granitoid magmatism in the Eastern Russia within the borders of the Far Eastern Federal District. The relevance of the work is determined ...
-
(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 ...
