-
(2002)Geological interpretations of crystal size distributions (CSDs) depend on understanding the crystal growth laws that generated the distributions. Most descriptions of crystal growth, including a population-balance modeling ...
-
(2004)Grid representation of 3-D media and linear interpolation functions have been widely used in recent seismic traveltime tomographic studies. Either velocity or slowness is used as a model parameter in such studies, which ...
-
(2004)The probability of 2–3 h variation in electron concentration at different regions of ionosphere 1–3 days before earthquakes at distances R<500 km from vertical sounding stations was analyzed. Using 12 months of data sampled ...
-
(1998)Different approaches to the Rb-Sr dating of clayey rocks are discussed, and arguments against using the whole-rock samples for this purpose are present. Much more effective and methodologically correct is the dating of ...
-
(2002)The purpose of this paper is to extend the locally based prediction methodology of BayMar to a global one by modelling discrete spatial structures as Markov random fields. BayMar uses one-dimensional Markov-properties for ...
-
(2001)This note intends to address a misnomer in flood routing. The noninertia wave, which ignores both local and convective inertia terms in the momentum equation, is a simplification to the full dynamic wave. While the diffusion ...
-
(2001)Operation of powerful vibration-seismic sources has been considered. They are used for excitation of seismic waves in geological medium. The first developed vibration-seismic sources are characterized by some disadvantages. ...
-
(2001)The paper describes the results of research of the alkaline-ultramafic complex in Turiy peninsula. In the course of the research ijolite veins of the late alkaline series of the complex have been investigated. These bodies ...
-
(2001)A possibility of using the Permian global chronostratigraphic scale in the Tethyan region is estimated in this work. Permian successions in this region show that the proposed subdivision of the Permian System into the ...
-
(2003)Modern analyses of sea level changes due to glacial isostatic adjustment (GIA) are based on the classic sea level equation derived by Farrell & Clark (1976, Geophys. J.R. astr. Soc., 46, 647-667). The connection between ...
-
(2001)Effect of electromagnetic emission for rock destruction site has been considered. Mathematical model of process of crack accumulation has been discussed. It has been shown that solution of problem of algorithm synthesis ...
-
(2003)Formation of rhythmical layering in intrusive basic and ultrabasic rock bodies is explained in different ways, in particular, by the movement of microparticles (mineral clusters) of plagioclase and pyroxene within the ...
-
(2002)Incorporation of hydrocarbons (CH4, C2H6, C3H8, C4H10) in cordierite channels was experimentally studied at 700 °C and at pressures from 200 to 1000 MPa, (avoiding recrystallization). The maximum concentrations of hydrocarbons ...
-
(2001)The wide use of cosmogenic nuclides for dating terrestrial landforms has prompted a renewed interest in characterizing the spatial distribution of terrestrial cosmic rays. Cosmic-ray measurements from neutron monitors, ...
-
(2003)The exact solution to the problem of qSV triplication in homogenous transversely isotropic media has been long known, but the result is algebraically complex and is seldom applied in practice. We present an appropriate ...
-
(2004)Aberrations of the extant species Equisetum hyemale L. are described. In one type of aberrations, the strobili are laterally disposed on short secondary shoots, thus resembling the arrangement of strobili in Mesozoic members ...
-
(2001)Debye potentials and vector spherical harmonics were applied to a magnetostatic problem. By these mathematical methods it is shown that the inverse problem of the magnetostatics cannot be solved though the divergence of ...
-
(2004)On the basis of new material on Permian somoholitids from the Subpolar Ural Mountains, the diagnosis of the genus Andrianovia is emended. The transition from Somoholites to Andrianovia is discussed. A new species Andrianovia ...
