(2001)In addition to the use of Janecke units in the NaCl-KCl-MgCl2-Na2SO4-H2O/NaCl-KCl-MgCl2-CaCl2-H2O system to classify brine origins, a fast and efficient method is described to identify inclusions of evaporated seawater in ...
-
(1986)Most models of high-alumina arc basalt petrogenesis rely heavily on the supposition that the abundances of certain trace elements, in particular the relatively unfractionated Rare Earth Element (REE) patterns and the ...
-
(2001)Optical anomalies (deviations of the symmetry of optical properties from the ideal symmetry of the crystal) occur in many minerals and synthetic compounds and have been under investigation since the last century. An important ...
-
(2004)The paper is motivated by our recent results of observation on the satellites Cosmos-900, Aureol-3 and Intercosmos-24, which are presented in this issue (Molchanov et al.). We try to show that a drift mode leading to the ...
-
(2004)Under certain conditions the formation of the Moon from a primary material similar in composition to CI chondrites can meet the well-known geochemical criteria, including the deficit of iron in the Moon, its depletion in ...
-
(1981)Recent slow vertical movements in Sakhalin, Japan and Kamchatka are mainly the continuation of modern movements that began in the Quaternary and older periods. In many cases positive and negative Recent vertical movements ...
-
(2003)Crystal growth experiments were conducted using potassium alum and calcite crystals in aqueous solution under both non-stirred and stirred conditions to elucidate the mechanism for size-dependent (proportionate) and ...
-
(2000)Experiments conducted by the Laboratory of Seismology, Institute of Oceanology, Russian Academy of Sciences showed that bottom currents excited free oscillations of ocean bottom seismographs (OBS) of the pop-up type. These ...
-
(1990)Kimberlites are considered to be products of crystallization of melts formed in 'fluidization and magmatic replacement' or by the disintegration and partial melting of rocks from great depth, the incompletely melted remains ...
-
(2003)Previous cladistic studies of pterosaur relationships suffer from restricted numbers of taxa and characters, incomplete data sets and absence of information on characters, tree structure and the robustness of trees. Parsimony ...
-
(2003)In a diamond from New South Wales (Australia), cubic and octahedral growth sectors, as identified by cathodoluminescence (CL), show slight differences in N-contents of 29 and 42 ppm respectively but no significant differences ...
-
(2000)Results from recent tomographic imaging of the mantle have revealed plume-like structures under some hotspots and renewed the interest in the theoretically possible forms of ascending jets in mantle convection. It is now ...
-
(2001)The idea of a statistical analysis of the distribution of hydrothermally synthesized single sulfide crystals using their gold contents is developed specifically to distinguish the structurally bound gold component. Mercury ...
-
(1996)Seismic tomography has proven to be a powerful method for studying three-dimensional properties of the Earth's interior. Using seismic waves, however, limits the principally accessible period range to periods less than 1 ...
-
(2003)Archaeomagnetism can provide a high-resolution full-vector description of the Earth’s magnetic field for the past several thousand years. We analyse the bulk of archaeomagnetic data (both direction and intensity) obtained ...
-
(2001)The investigation of boring patterns made by modern nonmarine Puerto Rican neritids suggests that the capability of prédation and boring may have evolved in extant and fossil brackish-water representatives of Theodoxus ...
-
(1998)Usually the topographic-isostatic geoid undulation is derived by a downward continuation of the external potential to the geoid. Unfortunately, such an approach merely yields a fictitious potential at the continental geoid ...
-
(1990)The earthquake under consideration was similar in origin to other strong tremors registered in the Karakul-Momuk fault zone. They all fully reflected the geologic conditions of earthquake generation in the zone. The fact ...
-
(1999)This study questions the assumption that silicate melts preserved as glass inclusions in minerals and as interstitial films or pockets in mantle xenoliths have identical chemical compositions to one another and are both ...
-
(1997)Quantitative models for dynamics of the evolution of ore-magmatic systems have been developed quite irregularly. The most advanced approach is the mathematical modeling of heat and mass transfer processes for the case of ...
