(2006)Re-Os isotopic systematics is the best tracer on studying the ophiolitic peridotite because, in contrast with the geochemical properties of Sm-Nd, Rb-Sr, U-Th-Pb and Lu-Hf, all of which are incompatible elements, Os is a ...
-
(2001)Chromite refers to the mineral (Mg, Fe) (Al, Cr, Fe)2O4in which the chromicoxide content varies typically between 15 and 65%; iron exists in both di andtrivalent states; minor compounds of significance are ...
-
(2003)Whilst faulting in the shallow crust is inevitably associated with comminution of rocks, the mechanical properties of the comminuted granular materials themselves affect the slip behavior of faults. Therefore, the mechanical ...
-
(2001)Overpressure build-up in compartments, and communication between overpressured compartments across faults are studied with simple analytical and numerical models. It is shown that the excess pressure in a (vertical) ...
-
(2002)Intergranular pressure solution (IPS) is an important compaction and deformation mechanism in quartzose rocks, but the kinetics and rate-controlling process remain unclear. The aim of the present study is to test microphysical ...
-
(2001)Most compaction models in the partially molten mantle have addressed the case of low intergranular melt concentrations (up to a few percent). Here we develop a mathematical and numerical formalism adapted to the two-dimensional ...
-
(2002)A general formulation of compaction problems is described and the classification of these problems in accordance with boundary conditions is presented. A basically new class of compaction boundary problems in a finite ...
-
COMPACTION OF QUARTZ SANDS BY PRESSURE SOLUTION USING A COLE-COLE DISTRIBUTION OF RELAXATION TIMES (2006)Stressed water-infiltrated silica rocks may deform by pervasive pressure solution transfer (PPST), which involves dissolution of the grain-to-grain contacts, transport by diffusion of the solute, and precipitation on the ...
-
(1998)Compaction driven fluid flow is inherently unstable such that an obstruction to upward fluid flow (i.e. a shock) may induce fluid-filled waves of porosity, propagated by dilational deformation due to an effective pressure ...
-
(2002)A suite of 47 carbonaceous, enstatite, and ordinary chondrites are examined for Re-Os isotopic systematics. There are significant differences in the 187Re/188Os and 187Os/188Os ratios of carbonaceous chondrites compared ...
-
(2003)Previous research has shown that the sections of the vast volcanogenic trap field of the Siberian Platform bear analogs of oceanic A- and C-G-type plateau basalts. Comparative analysis of volcanic rocks shows that basalts ...
-
COMPARATIVE ANALYSIS OF GEODYNAMIC SETTINGS OF THE PERMO-TRIASSIC MAGMATISM IN EAST AND WEST SIBERIA (1999)A comparative analysis of the chemical composition of Permo-Triassic volcanics from the Siberian Platform and pre-Jurassic basement of the West-Siberian plate was performed to elucidate the geodynamics of magmatism in these ...
-
(2002)Thermodynamic simulation techniques of infiltration-controlled metasomatic columns based on the local equilibrium principle are analyzed. The validity criteria of the results were corollaries from D.S. Korzhinskii's theory ...
-
(2003)Comparative characteristic of spore-pollen assemblages from the Son'e (late Eocene), Bui, Svetlovodnaya (late Eocene-early Oligocene), Amgu (late Oligocene-early Miocene), Dembi, Velikaya Kema (late early Miocene-earliest ...
-
COMPARATIVE ANALYSIS OF THE MICROELEMENT COMPOSITION OF SESTON AND BOTTOM SEDIMENTS IN THE WHITE SEA (2006)Несмотря на то что планктон играет важную роль в биогеоХ:имических процессах, происходящих в океане, данных о его элементном составе все же недостаточно, особенно для шельфовых морей Арктики. Настоящая работа посвящена ...

(Федеральное государственное бюджетное образовательное учреждение высшего образования «Санкт-Петербургский горный университет», 2017)The physicochemical properties of heavy oils of Yaregskoe and Usinskoe deposits and the residues of atmospheric distillation of petroleum (fuel oil) recovered from them are presented. The group composition of oil and the ...
-
(1999)According to the present day knowledge, the stratigraphic equivalents of the Early Miocene volcanic rocks of Sakhalin in the East Sikhote-Alin must be the rocks of the Dembi Suite, a constituent of the Kizinsky Formation ...
-
(1995)Linear free energy relationships (LFERs) have been used to assess the general character of rare earth element (REE) solution complexation. These analyses demonstrate that the coherence of interelement complexation behavior ...
