-
(2004)Morphology and growth mechanisms of diamond crystals in polycrystalline films synthesized from hydrocarbon gas have been studied under an electron microscope using secondary electron images. It was found that at the earlier ...
-
(1998)This paper describes morphometric measurements made in Lake Karymskoe in connection with the underwater eruption of January 1996. Echo sounding was carried out in April-September of 1996. Bathymetric maps were plotted for ...
-
(1988)This article discusses the shape characteristics of iron-manganese nodules and their dependence on the chemical composition and growth rate of the nodules. A sample of length of three axes for 609 nodules from the ...
-
(2003)Knowledge of mineral aggregate morphologies is of importance to analyze characteristic differences in rock-forming features. For quantifying these differences, the fractal geometry of quartz aggregate cuts digitized from ...
-
(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 ...
