(1998)The available data on compositional zoning in grossular-andradite (grandite) garnets occurring at different scales, mainly due to the variations of their Fe3+/Al ratios, and the hypotheses on the origin of this zoning are ...
-
(1990)Study of regions of the lateritic weathering of carbonatites shows that among the supergene products developed in them, rocks differing essentially in composition can be distinguished, and that these correspond to fundamentally ...
-
(2002)The data available on the crustal structure of the Balygychan-Sugoi Trough and the mineralogy and geochemistry of the Mesozoic and Cenozoic gabbro, acid volcanics, and post-magmatic minerals of the Dukat Au-Ag ore field, ...
-
(2001)The compositional characteristics of mantle xenoliths of the grospydite and coesite depth subfacies from the Internatsional'naya, Aikhal, Udachnaya-West, Udachnaya-East, Yubileinaya, Mir, Zarnitsa, Komsomol'skaya, Sytykanskaya, ...
-
(2002)In this paper we present an analytical formulation of the derived distribution of peak flood and maximum annual peak flood, starting from a simplified description of rainfall and surface runoff processes, and we show how ...
-
(1997)The main difficulty in using the Coulomb-Mohr theory for estimating shear as a mode of failure is that this theory does not take into account the tilt or rotation of the shear surface at a given strain, which have to be ...
-
(1996)As a basis for many applications the terrestrial reference frame has to be determined and maintained with high accuracy. This implies the investigation of different geodetic and geodynamic parameters as well as the application ...
-
(1998)A linear potential theory was used for a comparative analysis of tsunami waves excited by piston-type and traveling sea-floor displacements. It is shown that the parameters of these waves depend considerably on the type ...
-
(2001)The poor results of computations concerning the motions of the solid inner core of a slowly rotating, ellipsoidal earth model can be explained by the fact that Smith neglected in the equations of motion second-order terms ...
-
(2002)New material on the Early Bovidae (Hanhaicerus) from Mongolia is described. Phylogenetic relationships between Hanhaicerus and Palaeohypsodontus and other bovids are considered.
-
(2003)Both ancient and modern brachiopods provide examples of how adverse environmental conditions (e.g., in marginal areas and submarine caves, on seamount tops, and in the proximity of hydrothermal fields) result in such ...
-
(1998)Modern nutation theories of the Earth and planets use the assumption, that the planetҳ inertia ellipsoid is symmetrical about the axes of rotation. Below we estimate the effects of the inertia ellipsoid triaxiality accurate ...
-
(2003)A high conductivity zone (HCZ) exists in many places worldwide in the stable mid- to lower continental crust, at the depth of about 20–30 km, but its origin is enigmatic. At this depth range, the temperatures are constrained ...
-
(2004)A new method of modelling scattered seismic pulses is developed, based on the deformation that suffers an initial pulse due to scattering and on a reinterpretation of the product of convolution of a Green function with a ...
-
(2004)Simple cokriging of components of a p-dimensional second-order stationary random process is considered. Necessary and sufficient conditions under which simple cokriging is equivalent to simple kriging are given. Essentially ...
-
(2005)Simple relations are obtained for estimating stresses in the mantle at the time moment of a large meteorite fall from values of the velocity and mass of the meteorite and the sizes of its crater. It is shown that the fall ...
-
(1999)This is a study of the evolution of crustal magma chambers beneath volcanoes driven by the melting of host rocks and the discharge of molten material by eruptions. A qualitative and quantitative description is given for ...
-
(2004)The polarization method for recognition of seismomagnetic waves against a noise background is presented. The method is applied to detection of magnetic oscillations accompanying the propagation of surface Love wave after ...
-
(2000)The motion of plumes through compositionally layered systems is investigated by laboratory experiments in order to understand the ascent modes of deep mantle plumes. Experimental plumes entrain the ambient heavier fluid ...
