-
(2003)Instantaneous velocity gradients within the continental lithosphere are often related to the tectonic driving forces. This relationship is direct if the forces are secular, as for the case of loading of a locked section ...
-
THE RELATIONSHIP OF RECENT VERTICAL MOVEMENTS TO THE MORPHOSTRUCTURAL PATTERN OF THE KAZAKH SHIELD (1992)The geodetic data on recent vertical crustal movements within the Kazakh shields is in good correlation with its development in the Holocene (according to a study of juvenile river terraces); they point to gradual transition ...
-
(2004)Joint fractography in European plutons frequently shows large fringe-tilt angles connected to small fringe-crack twist angles (type A). In contrast to this first type, fringes of joints that tilt at small angles out of the ...
-
(2004)A suite of 22 members of the heterophyllosilicate astrophyllite-group from SiO 2 -over-and undersaturated igneous rocks were studied by single-crystal X-ray diffraction, wave-length dispersive electron microscopy and room ...
-
(1999)The sulfur contents at sulfide saturation (SCSS) of a basaltic and a picritic melt have been measured experimentally as a function of pressure and temperature from 5 to 90 kb and 1400-1800°C, using piston-cylinder and ...
-
(2002)We performed a systematic high-precision secondary ion mass spectrometry 26Al-26Mg isotopic study for 11 ferromagnesian chondrules from the highly unequilibrated ordinary chondrite Bishunpur (LL3.1). The chondrules are ...
-
(2001)The Re–Os (rhenium–osmium) chronometer applied to molybdenite (MoS2) is now demonstrated to be remarkably robust, surviving intense deformation and high-grade thermal metamorphism. Successful dating of molybdenite is ...

(2002)The project “Volgaforest” was focused on a study of the water budget of the forested Upper Volga catchment in Russia in order to describe:•the terrestrial water balance of the Upper Volga catchment as a function of external ...
-
(Pleiades Publishing, Ltd. (Плеадес Паблишинг, Лтд) (Род-Таун), 2007)Forced and free oscillations of water level were recorded in well YuZ-5, Kamchatka due to the passage of seismic waves from the Sumatra-Andaman earthquake of December 26, 2004, Mw = 9.3, hypocentral distance 8250 km. The ...
-
(Общество с ограниченной ответственностью «Георесурсы», 2018)A method is proposed for interpreting thermogasdynamic studies of vertical gas wells that are incomplete in terms of the reservoir penetration degree on the basis of inverse problem theory. The inverse problem has the aim ...
-
(PANGAEA, 1990-05-01)Limno-glacial deposits 110 cm in thickness in the upper alpine belt have been investigated. It is established that during the Yuanakhchiri period of glaciation in the region under study a glacial cirque was situated at an ...
-
(1999)Formation of secondary Ni precipitates is an important mechanism of Ni retention in neutral and alkaline clay/water systems. However, the structure and composition of these secondary phases, and their stability is still ...
-
(1998)The low atomic mass elements B, Be, and Li are viewed as sensitive tracers of the involvement of subducted materials in the genesis of island arc magmas. In order to better assess the role of dense aqueous fluids in the ...
-
(1997)An analysis is presented that allows the evaluation of the effect of attenuation on acoustic emission amplitude distributions and b-values obtained during the deformation of geomaterials in laboratory experiments. It is ...
-
(1999)Using a coupled fluid flow-mass transfer model to calculate the Sr flux resulting from the weathering of the young Columbia River basalts, it can be shown that the dissolution of the reactive phases in the extensive ...
-
(2001)The paper examines the peculiar features of tourmaline-quartz type gold deposits distribution in the earth's crust, as well as its occurrence and principal mineralogical and geochemical features. Presumably, metal borides ...
-
(2006)The influence of citrate and phthalate on Co coprecipitation with calcite was investigated using a combination of batch experiments, Fourier-transform infra-red (FT-IR) spectroscopy, and thermogravimetric analysis (TGA) ...
