-
(2004)Isostatic gravity anomalies were inverted under the assumption that compensation of topographic loads is only partly provided by Moho depth variations but is to a large extent due to the geometry of the lithosphere/asthenosphere ...
-
(2002)An approach is presented to calibrate and use regional P-S amplitude ratios to improve seismic-event characterization capabilities with regard to monitoring the Comprehensive Nuclear-Test-Ban Treaty. Data for presumed ...
-
(2001)We have developed a regional sequence stratigraphic framework for the productive Neocomian complex of central West Siberia. Sixteen depositional sequences have been identified on the basis of analysis of regional seismic ...
-
(2001)This study establishes a method for evaluating the coefficients of tank model. First, the model coefficients were optimized using the Standardized Powell Method at 12 watersheds. Then 16 characteristics were derived from ...
-
(1988)The periodicity of geologic processes is one of the main, still unsolved problems of geology. The study of geodynamic and metamorphism now allows this problem to be posed on a new level. The key to such an approach could ...
-
(1998)Most quantitative models of mantle mixing have been based on simulations of tracer advection by 2-D flows. The present work shows that the mixing properties of 3-D time-independent flows cannot be understood or extrapolated ...
-
(2001)The evolution of foraminifers during the Jurassic is considered in two aspects. The evolutionary aspect proper was analyzed using the internal biological features of these organisms and history of this faunal group was ...
-
(2001)The analysis of geotectonic settings and the planetary distribution of phosphate ores revealed that apatite deposits are confined to the continental rift zones with the uplifted Moho discontinuity, while phosphorite deposits ...
-
(1998)Processes responsible for the alternation of flora evolution stages are analyzed on the basis of the Late Cretaceous floras from northeastern Russia, among them two paleofloral successions from the Penzhina Bay ...
-
(2003)A principal feature of stratiform basic-ultrabasic intrusions is alternation of rocks characterized by different proportions of the salic (plagioclase) and mafic (mainly pyroxene) constituents. Owing to considerable density ...
-
(2003)A sequence of aftershocks is modelled assuming fluid migration in a narrow, porous fault zone formed along a vertical strike-slip fault in a semi-infinite elastic medium. The principle of the effective stress coupled to ...
-
(2001)Controversy still exists on whether rhythmic features such as beach cusps are the result of the presence of standing edge wave motions in the hydrodynamics or if they are the result of self-organising processes. The ...
-
(2003)Spherical cap harmonic analysis has become a well-known technique for regional modelling of fields that can be expressed as the gradient of a scalar potential, such as for example the geomagnetic field and its secular ...
-
(2003)Voluminous, unzoned, phenocryst-rich pyroclastic deposits, considered as erupted batholiths, provide a unique opportunity to investigate magmatic processes in silicic magmas. The Fish Canyon Tuff, a well-documented example ...
-
(2001)This paper is concerned with the question of how to relate laboratory measurements of the rheology of rocks to the rheological assumptions that need to be made in geodynamic modelling. First, there is a brief resume of the ...
-
(1999)In a thermodynamic description of a mineral solid solution, it is customary to select a minimal group of end-members that constitutes an independent set, and yet in practical calculations it commonly occurs that a different ...
-
(2004)We present evidence that the Hurst exponent of the ultra low frequency component of the geomagnetic field varies similarly to the energy release of the local swarm of earthquakes observed in Japan in 2000. Similarity is ...
-
(1998)Evidence from the Late Mesozoic Okhotsk-Chukchi Volcanogenic Belt confirmed the view of V.V. Averiev that 'the hot aqueous fluid should be regarded as the main agent in a special form of volcanism wherein explosive phenomena, ...
-
(1996)On the basis of seismic data analysis and the Debye model of solid bodies it is proved for the first time that fundamental connections exist between the source volume, elastic waves distribution velocity, boundary vibrational ...
