-
(1999)The new maps of Quaternary and recent tectonic movements were compiled with the use of new geologiegéomorphologie and geodetic data.
-
(1997)The Holocene deformations of the central part of the Tien Shan mountain range in Kazakstan were studied in the field and by photointerpretation in order to reconstruct the geometry, kinematics and rate of faulting. The ...
-
(1990)The mountains of north-eastern Inner Asia comprise the Mongolia-Siberian orogenic belt which has a complex structure. The southern flank of the belt consists of a chain of large domal uplifts. The Baikal rift zone is located ...
-
(2001)The morphological variability of Stenocranius gregalis Pallas from the Paleolithic site Denisova Cave (Altai) is examined. The variability of the unpaired anterior loop of M] is discussed. Seven morphological types are ...
-
(1987)The main results are presented of an analysis of the structures of the seismograms. Structure is understood to mean the set of the following factors characteristic of the wave field: number of regular waves, their relative ...
-
(2000)(Mg,Fe)(Si,Al)O3 perovskite samples with varying Fe and Al concentration were synthesised at high pressure and temperature at varying conditions of oxygen fugacity using a multianvil press, and were characterised using ex ...
-
(2001)The electronic structure of iron-rich epidote has been investigated by cluster molecular orbital calculations in local spin density approximation. Calculated quadrupole splittings for Fe(III) at both the M1 and M3 sites ...

MOSSBAUER SPECTROSCOPIC EVIDENCE FOR NONEQUIVALENT SITES OF IRON ATOMS IN GOLD-BEARING ARSENOPYRITE (2003)Eight samples of arsenopyrite from the Kochkar (Southern Urals) and Nezhdaninskoe (Siberia) deposits were studied by the method of Fe-57 Mossbauer spectroscopy. The mineral samples showed considerable variations in arsenic ...
-
(2001)Transmission Mössbauer spectra of synthetic Ca-free P21/c Mg0.22Fe0.78SiO3 clinopyroxene were collected at temperatures in the range 4.2 to 745K and in an external magnetic field of 60kOe at 180K. The magnetic order-disorder ...
-
(2001)We consider the time evolution of seismic primary arrivals in single realizations of randomly heterogeneous media. Using the Rytov approximation, we construct the Green's function of an initially plane wave propagating in ...
-
(1993)Three of four Plinian eruptions from Ksudach Volcano are among the four largest explosive eruptions in southern Kamchatka during the past 2000 years. The earliest of the eruptions was voluminous and was accompanied by an ...
-
(2003)A new element of the World Climate Research Programme (WCRP) has been inaugurated addressing the role of the cryosphere in climate. A Science and Co-ordination Plan has been issued for the Climate and Cryosphere (CliC) ...
-
(2003)Outlines and parameters of glaciers formed during the Pleistocene Last Glacial maximum (MIS 2) have been reconstructed based on remote sensing and field investigation of the glaciology and geomorphology of a 3293 km2 key ...
-
(2001)Calculations of parameters of movement of rock blocks during large-scale dynamic action have been performed. Results of the calculations have been presented. Evaluations made according to analytic models and experimental ...
-
(2003)Flow and transport in soil is governed by the binary geometry of solid and void. This may be described at typical length scales of some millimeters, and even less. In contrast, the problems which are supposed to be solved ...
-
(2004)One of the most widely used methods to estimate magmatic oxygen fugacity involves the use of empirical equations relating fO2 to the iron redox state in quenched silicate liquids; however none of the equations have been ...
-
(2004)The South Caspian sedimentary basin is a unique area with thick Mesozoic-Cenozoic sediments (up to 30–32 km) characterized by an extremely high fluid generation potential. The large amount of active mud volcanoes and the ...
-
(2006)In this paper, an effort is made to consider mud volcanism of northwestern Caucasus from the most complete data including data on the abutting seas water areas and available data on ancient mud volcanoes. A number of new ...
-
MUD VOLCANOES AND MICROSEEPAGE: THE FORGOTTEN GEOPHYSICAL COMPONENTS OF ATMOSPHERIC METHANE BUDGET (2005)Mud volcanoes and microseepage are two important natural sources of atmospheric methane, controlled by neoritectonics and seismicity. Petroleum and gas reservoirs are the deep sources, and faults and fractured rocks serve ...
-
(2001)The general description of a mud volcano is an injection or eruption of mud fluids from a highly pressurized zone to a shallower, lower-pressure zone or eruption to the surface. These features are often associated with gas ...
