-
(2001)Phenomenon of amplification of seismic waves near faults has been considered. Theory describing amplification of rock destruction near faults has been generalized for case of uniform waves which are incident at angle upon ...
-
ON AN AVERAGED MODEL FOR THE 2-FLUID IMMISCIBLE FLOW WITH SURFACE TENSION IN A THIN CYLINDRICAL TUBE (2003)We consider the two-fluid incompressible immiscible flow, with surface tension, in a thin cylindrical tube. Using the method of asymptotic expansions with respect to the thickness of the domain, effective 1D equations are ...
-
(1998)Specifies of the calculations of the reduced isotopic partition function ratios (β-factor) of minerals are discussed. Comparative calculations in the framework of the fully harmonic, quasi-harmonic, and intrinsic anharmonic ...
-
(1995)Methodological issues of the use of vibrators and vibration apparatus in engineering and seismological measurements are considered. Application of vibrators in testing of buildings and in microseismic regionalization allows ...
-
(2001)The collection numbers of A.G. Vologdin, A.N. Vlasov, Yu.I. Voronin, K.N. Konjuschkov, and V.I. Yaworski on archaeocyaths and certain other Vendian and Cambrian fossils, which were transferred to the Stock Division of the ...
-
(2001)Sr-Ba-Ca-carbonates (which were initially identified as benstonite MgCa6Ba6(CO3)(13)) from carbonatite of the Murun, Aldan, and Jogipatti, Southern India, alkali massifs were studied by a complex of methods (X-ray diffraction, ...
-
(2002)Extensive, coarse-grained silicic lenses are common in the upper portions of large diabase sills, lava lakes, and gabbroic intrusions. These lenses, which often contain up to 10 wt% more silica than their host rocks, record ...
-
(2001)Morton's proof of Bouchet's complementary hypothesis has been revisited. The proof's central assumption is that an increase in sensible heat from the surface to the air induces a similar increment in the sensible heat ...
-
(2000)The history of hydrologic and faunal changes in the Eastern Paratethys during the middle and late Miocene is briefly outlined. An effort is made to establish the location of straits, through which marine waters penetrated ...
-
(1999)When a saturated basaltic magma cools and crystallises in a shallow magma reservoir, gas bubbles may be exsolved from solution, thereby influencing the density, convective mixing and pressure evolution of the melt. In wet ...
-
(1989)The well known absence of magrnatic superheat is held here to be a direct reflection of the ease and efficiency of large Rayleigh number (Ra) convection in evacuating all convectable heat from the magma. Magmatic temperature ...
-
(2003)Suppose that values in a finite sequence of data are labelled as either +1 or -1 depending, respectively, on whether they are either above or below the median. Using this sequence of +1 and -1 s a unit-lag autocorrelation ...
-
ON DETERMINING THE SILICA IN MAGMATIC ROCKS UNDER BOREHOLE CONDITIONS BY NUCLEAR GEOPHYSICAL METHODS (1990)In studying rocks and complexes of rocks by geophysical methods, it is important to obtain information on the main groups to which the rocks belong. The successes of electric well logging in sedimentary sections, for ...
-
ON DYNAMIC BEHAVIOR OF THE 'SELF-STRESSED' BLOCK MEDIA: ONE-DIMENSIONAL MECHANICO-MATHEMATICAL MODEL (2001)A mechanico-mathematical statement of the problem on dynamic behavior of "self-stressed" block geomedia within a one-dimensional model is given. The structural elements of this model are considered to be absolutely solid ...
-
(2005)Early Solar System chronology is usually built with the assumption that the distribution of short-lived radionuclides was homogeneous through the solar accretion disk. At present, there is no unambiguous evidence for a ...
-
(2002)Dedicated satellite-to-satellite tracking (SST) or gradiometry missions like GRACE and GOCE will provide gravity field information with unprecedented resolution and precision. It has been recognized that better gravity ...
-
(2002)A large data base of 1821 chromian spinel compositions (Cr2O3 > 2 wt%) in ultramafic nodules from basalts, kimberlites, lamproites, ultramafic massifs, and from the diamond assemblage has been analyzed using mathematical ...
-
(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 ...
