-
(1989)Since the middle of the 1970's, the Yuzhmorgeologiya Survey had been systematically studying the part of the Northeast Pacific Basin near the equator by the methods of seismoacoustic profiling and echo sounding, combined ...
-
(2003)Compressional and shear wave velocities of ringwoodite (gamma-Mg(2)SiO(4)) were measured on a polycrystalline specimen to 12 GPa at room temperature using ultrasonic interferometry techniques. Velocity measurements at ...
-
(2002)We performed two-dimensional finite-element numerical modeling of subduction to study the deformation and failure pattern of an overriding plate. This plate has elasto-plastic rheology with strain weakening and contains a ...
-
(2002)Compressional wave velocities (VP) at above-solidus temperatures and at 1 GPa were obtained for a granite and amphibolite, which are considered to be major constituents of the continental crust. The temperature variation ...
-
(2005)An algorithm for the construction of phase diagram sections is formulated that is well suited for geodynamic problems in which it is necessary to assess the influence of phase transitions on rock properties or the evolution ...
-
(2003)In sediments, the diaromatic carotenoid isorenieratene can undergo a wide range of molecular transformations, including cyclisation reactions via a Diels-Alder mechanism resulting in either mono- and diaromatic compounds ...
-
(2001)Solute discharge moments (mean and variance) are computed using numerical modeling of flow and advective transport in two-dimensional heterogeneous aquifers and are compared to theoretical results. The solute discharge ...
-
(2003)As part of a wider study of the nature and origins of cation order-disorder in micas, a variety of computational techniques have been used to investigate the nature of tetrahedral and octahedral ordering in phengite, ...
-
(2001)The nature of Al–Si ordering across the tetrahedral sites in muscovite, K2Al4(Si6Al2O20)(OH)4, was investigated using various computational techniques. Values of the atomic exchange interaction parameters J l were obtained. ...
-
(2002)Describes the application of computer-graphics animation techniques to enhance the understanding of mineral crystal growth. Choice of core mineral structure; Effects of differential growth rates on modified crystal habits; ...
-
(2004)Based on the analysis of published data, results of experimental investigations, and computer simulation, the constants of ion exchange reactions on clay minerals were determined and the factors affecting these constants ...
-
(1996)A previously developed software was used to process earthquakes recorded at different epicentral distances by an IRIS-2 digital seismic system. The following statistical uncertainty estimates of preliminary S-wave onset ...
-
(1998)Monte Carlo and molecular dynamics computer simulations are now able to provide detailed information concerning the structure, dynamics, and thermodynamics of pore fluids in 2:1 clays. This article will discuss interparticle ...
-
(2002)Defect structure and the defect formation in mullites and sillimanites have been investigated using computer simulation techniques. From point defect chemistry and computer simulations, oxygen vacancies are identified as ...
-
(2004)Cation distributions (CDs) in the representative collection of trans-vacant dioctahedral celadonites, glauconites and ferriillites were investigated using Mössbauer and IR spectroscopies and the original approach. The ...
-
(1998)The lattice dynamics computer code PARAPOCS was successfully used to calculate the 240 vibrational frequencies of pyrope garnet, Mg 3 Al 2 Si 3 O 12 , at ambient conditions. The atomic displacement vectors (eigenvectors) ...
-
(2003)Computer speciation models of antimony in aqueous, multicomponent solutions of environmental and biological interest have been developed. Antimony is an element of increasing environmental significance but one whose chemical ...
-
(2001)Principles of construction of computer-aided systems for physical modeling of block geological medium behavior have been developed. This has made it possible to create the computer-aided systems. Behavior of the block ...
-
(2001)Process of mining the inclined deposits has been considered. Mathematical model of the process has been developed. Conditions of open pit at the deposit have been discussed. Algorithm of determining the blocks of open pit, ...
