-
(1998)We propose an experimental evaluation of the simultaneous dissolution rate of K-feldspar, biotite and plagioclase during the interaction between a granite and a fluid artificially enriched in the less abundant strontium ...
-
(2003)The filtration of silicic-alkaline fluid through amphibolite is reproduced experimentally at a temperature of 750°C and a total pressure of 5 kbar, which enables modeling amphibolite granitization in an open system. The ...
-
(2004)The filtration of alkali- and silica-bearing solution through amphibolites of various mineral composition and structure was studied at a temperature of 750°C and a total pressure of 5 kbar. The laboratory experiments ...
-
(2002)Granitization of rocks in the Archean complex penetrated by the Kola Superdeep Borehole is manifested in the development of nebular, patchy, and unclearly banded migmatites with an age of 2.2 Ga. The amounts of migmatitic ...
-
(2001)Natural deformation in carbonate mylonites bearing sheet silicates occurs via a complex interaction of granular flow and solution transfer processes and involves continuous cycles of dissolution, grain boundary diffusion, ...
-
(2003)In the Punggi area of the northeastern part of the Yeongnam Massif, one of Precambrian basement terrains in Korean Peninsular, the metamorphic grade increases from the amphibolite- to the granulite-facies zones towards the ...
-
(2001)There are both natural and experimental observations of the coexistence of three pyroxenes—orthopyroxene (Opx) + pigeonite (Pig) + augite (Aug)—with plagioclase (Pl). Commonly, the assemblage occurs as an intermediate ...
-
(1998)Unusual cuboid graphite aggregates (up to 13 mm edge length) from the eclogitic gneiss unit of the Maksyutov Complex deflect a foliation defined by groundmass graphite and phengite, and pressure shadows have developed ...
-
(2004)This document presents the International Committee for Coal and Organic Petrology (ICCP) classification of four organic components that cannot be included into any of the three maceral groups vitrinite, inertinite and ...
-
(2005)Graphite in deep crustal enderbitic (orthopyroxene + garnet + plagioclase + quartz) granulites (740°C, 8.9 kb) of Nilgiri hills, southern India were investigated for their spectroscopic and isotopic characteristics. Four ...
-
(1998)Melts produced under fluid-absent, graphite-saturated conditions have tightly constrained oxidation states and CO2 contents. A model is presented for the generation of mid-ocean ridge basalt (MORB) magma by fluid-absent ...
-
(2004)The Kalguta deposit is a typical representative of the molybdenum-rare metal-tungsten ore association that is widespread in Gornyi Altai. The deposit is confined to the late Hercynian Kalguta Massif of leucocratic rare ...
-
(2002)The graphitization of carbonaceous material (CM) in a high-pressure metamorphic gradient is characterized along a cross section in the Schistes Lustrs formation, Western Alps. Along this 25-km cross section, both the CM ...
-
(2002)We study the Rayleigh–Taylor instability of a structure consisting of a buoyant layer of viscous fluid overlain by a dense perfectly plastic layer (which is represented by a strongly non-Newtonian fluid with the power-law ...
-
(2002)Integral expressions are derived for the vertical component of gravitational attraction arising from vertical circular cylinders and horizontal circular disks with radial variation of density. The expressions contain a ...
-
(2002)A general integral expression is formulated for the gravitational attraction due to any solid of revolution based on the attraction of vertical, semi-infinite, circular, cylindrical shells. The expression accommodates ...
-
(2001)All geodynamic processes should be explained by the fundamental principle of the strive for gravitational equilibrium. [Ann. Soc. Geol. Belge Bull. 64 (1965) 95-123]The concept of gravitational collapse has fundamentally ...
-
(1990)In the present paper we discuss the compaction of rocks in terms of a model of macroscopically uniform compacting deformation of porous rocks, i.e., unilateral compression produced by the weight of a rock body. The associated ...
-
(2002)Models for the evolution of the Moon must explain a number of important characteristics of its magmatic history. Primary among them is the emplacement of mare basalts primarily on one side of the Moon, and in a region of ...
-
(2003)Initial equations are obtained, similarity criteria are estimated and a project of simulation experiment is proposed for the gravitational differentiation of liquid cores of planets and natural satellites. It is assumed ...
