SEISMOGENIC DEFORMATIONS IN EARLY HOLOCENE SEDIMENTS OF THE PECHENGA RIVER TERRACE (KOLA PENINSULA) (2006)The Kola Peninsula, an element of the northwestern Baltic Shield, is not a high-seismicity region at present. This has not always been the case, however, as is evident from seismic paleodeformations reflecting strong ...
-
(2004)We summarize seismogenic structures in four regions of active convergence, each at a different stage of the collision process, with particular emphases on unusual, deep-seated seismogenic zones that were recently discovered. ...
-
(2000)This study of seismogeodynamics and seismicity in North Eurasia was based on the idea of a structural, dynamic, and energy unity of the geophysical medium and of seismogeodynamic processes operating in it. This unity is ...
-
(2002)We present a semi-analytical, semi-numerical method to simulate wave propagation in piecewise heterogeneous media that the Earth presents. Wave propagation in such media will highlight the reflections/transmissions at ...
-
(1989)Seismogravitational oscillations are movements of the earth in which inertial and gravitational accelerations of similar magnitude are generated on its surface. These include the lowest-frequency characteristic oscillations ...
-
(2006)In the present paper we consider an anisotropically correlated percolation model of fracture (PMF), namely, the geometry of fracture structures, the energy emission model and the evolution of scatter of emitted (effective) ...
-
(2006)Crustal receiver functions (RFs) computed from the records of 45 temporary seismological stations installed on a 620-km-long profile across central Zagros provide the first direct evidence for crustal thickening in this ...
-
(2000)A new approach is proposed for mapping seismicity parameters. It incorporates the scale of the seismic process involved (precursory areas of large earthquakes) and interaction of seismicity at great distances. The concepts ...
-
(2001)A technique for determining volume deformation variations is suggested and substantiated theoretically on the basis of the multiple-reflection longitudinal waves specified in the seismograms from distant earthquakes. Results ...
-
(2006)Precise measurements of local magnetic fields have been obtained with a differentially connected array of seven synchronized proton magnetometers located along 60 km of the locked-to-creeping transition region of the San ...
-
(2006)During 1993-2002, a field experiment in the Miyun reservoir was carried out. A relation coefficient of -0.063 nT/m was obtained between geomagnetic changes and water depth variations in the reservoir, which agrees with ...
-
(2006)The Cyprian Arc forms the plate boundary between the Anatolian plate in the north and the Nubian and Sinai plates in the south. We examine the tectonic setting and seismic activity along the arc in light of new geodetic ...
-
(1995)Analysis of silicate minerals equilibrated at high pressure with silicate- (clinopyroxene) and carbonatite-melts (olivine, orthopyroxene, clinopyroxene, garnet, phlogopite) using proton- and electron-microprobe techniques, ...
-
(2004)The adsorption selectivity for C1–C6 hydrocarbons in a gas mixture on a variety of adsorbents was measured at 26 and 80 °C at total pressures of 1, 2 and 3 atm. The adsorption isotherm reveals that the adsorption levels ...
-
(2000)The comparative application of three complementary surface analytical techniques allows us to investigate the alteration process and to probe selectively, as a function of depth, the oxidation products of bornite, chalcopyrite ...
-
(2001)In soil magnetism, the magnetic parameters alone are not always sufficient to distinguish the lithogenic from the pedogenic magnetic fractions. Sequential extraction techniques have therefore been incorporated into magnetic ...
-
(2001)Processes of treatment of copper pyrite ores have been considered. The difficult-to-concentrate ores are widely utilized for producing the non-ferrous and noble metals. Particularities in concentration of the ores have ...
-
(1988)The authors compare data on concentrations of selenium and tellurium in granitoid rocks of different geochemical types and consider the behavior of these elements during granitoid magma differentiation. Selenium in the ...
