(2001)Multi-stage development of carbonate buildups has been recognised in the Bol'shaya Nadota Carbonate Complex, in the vicinity of the town of Inta (Subpolar Urals). The growth of typical stromatoporoid-coral bioherms, ...
-
(2003)Origin, growth, and steady existence of monodisperse silica spheres (MSS) composing precious opal are possible solely in concentrated alkaline solutions of silica. In Australian deserts, such solutions result from dissolution ...
-
(2004)We consider a depression in intensity of ULF magnetic pulsations, which is observed on the ground surface due to appearance of the irregularities in the ionosphere. It is supposed that oblique Alfven waves in the ULF ...
-
(2002)Samples of fine glass beads (mean grain size equal to 38 and 95 μm) have been depressurized within a vertical shock tube. These short-lived, rapid decompressions resemble discrete, cannon-like vulcanian explosions and ...
-
(2001)The correspondence between the predicted brittle–plastic transition within the crust and the maximum depth of earthquakes is examined in the case of the Baikal rift, Siberia. Although little accurate information on depths ...
-
(2000)This study is based on the detailed geometry of the Hokkaido Wadati-Benioff zone and the paleosubduction zone as delineated by Hanus and Vanek (1984). The used data includes 217 CMT Harvard solutions for earthquakes, which ...
-
(1985)The location of tectonic fields on the Ti/V discrimination diagram suggests that this ratio in least fractionated basalts may be a function of the depth to magma source. The hypothesis is tested using chronostratigraphic ...
-
(2001)A new methodology, three-variable hypersurface splines, is presented for depth solution of geological surfaces in a certain exploration field based on the integration of elevation data, obtained from drilling, and travel ...
-
(1999)Petrological data provide a new approach to an evaluation of the depth–age problem for ancient seafloor. The correlations among basalt chemical composition, axial depth and mantle temperature at current ocean ridges allow ...
-
DEPTH-DOMAIN PROCESSING OF TELESEISMIC RECEIVER FUNCTIONS AND GENERALIZED THREE-DIMENSIONAL IMAGING (2003)Stacking, either by itself or as a part of depth migration, is usually used for noise suppression in teleseismic receiver function (RF) images. However, stacking is neither the only signal enhancement method available, nor ...
-
(1986)The problem of deriving an optimal set of thermodynamic properties of minerals from a diverse experimental data base is reviewed and a preferred methodology proposed. Mathematical pro-gramming(MAP) methods extend the linear ...
-
(2001)The synthesis of petrological, geochemical, and isotopic data on granitoids from the Tyrnyauz area (El'dzhurtinskii Massif) and the critical analysis of the current petrologic-tectonic systematics of granitoids indicates ...

-
(2003)Glaciers have fluctuated in historic times and the length fluctuations of many glaciers are known. From these glacier length records, a climate reconstruction described in terms of a reconstruction of the equilibrium-line ...
-
(2004)Analyzing the geometric bias inherent to linear sampling of natural fracture systems is a prerequisite to any attempt of structural modeling. In this paper, the basic parameters of 1D-sampled fracture sets, i.e. orientation, ...
-
(2002)Manganlotharmeyerite, Ca(Mn3+,square,Mg)(2){AsO4,[AsO2(OH)(2)]}(2)(OH,H2O)(2), is a new member of the tsumcorite group of minerals, of general formula Me(1)Me(2)(2)(XO4)(2)(OH,H2O)(2), in which Me(1) represents Pb2+, Ca2+, ...
-
(2001)A new monobasic genus Eovavilovites (type species E. delinensis) is described from the Induan of Yakutia. The taxonomy and phylogeny of the new genus are discussed.
-
(2001)This paper considers recent contributions concerning metallic structures designed to stop rockfalls. These structures are composed of metallic nets generally made with Anti-Sub-Marine (ASM) rings. A constitutive modelling ...
-
(2001)A numerical design of an optimal regional seismograph network is discussed using Armenia as an example. The geometry of the seismic network operating in Armenia was analyzed and found to be imperfect. This impedes the ...
-
(2002)Length of day (l.o.d.) values deduced from fossils and tidal deposits suggest that the despinning rate was, on the average, about 5 times smaller during the Proterozoic than during the Phanerozoic and, moreover, that between ...
