-
(2002)The North Asia craton is a crustal block including the Siberian platform and marginal fold-and-thrust belts. On the eastern margin of the North Asia craton there is the Verkhoyansk fold-and-thrust belt making up the western ...
-
(2004)The Agardagh Tes-Chem ophiolite in Tuva, Central Asia, is part of the Central Asian Mobile Belt which formed during subduction-accretion processes lasting from the early Neoproterozoic to the late Palaeozoic. The ophiolite ...
-
(2004)On the basis of analysis of materials obtained in studying the inner structure of natural faults by geological and experimental methods, main types of structural environments for localization of ore fields have been ...
-
(2001)The Angara fault zone that extends from the Baikal Rift into the Siberian Platform through the most densely populated regions of Siberia has been investigated using geological and structural data. A database including 243 ...
-
(1998)Volcanogenic-siliceous and sedimentary-volcanogenic rock complexes are distinguished in the Anastasiya Bay area (the Koryak Highland) in the western coast of the Aleutian Basin. The age of siliceous beds in these complexes ...
-
(1996)Enthalpy relaxation of a reheated natural tektite glass has been used to determine the cooling-rate of the glass in nature. The relaxation parameters for the tektite samples were obtained by internal calibration through a ...
-
(2003)Teleseismic P-n phases with a long, high-amplitude coda, are observed to offsets 3000 km along the Peaceful Nuclear Explosion seismic profiles Quartz and Ruby. For the high-frequency (5 Hz) part of the Quartz data, which ...
-
(2005)New precise Te isotope data acquired by multiple collector inductively coupled plasma mass spectrometry (MC-ICPMS) are presented for selected extraterrestrial and terrestrial materials. Bulk samples of carbonaceous, ordinary ...
-
(2001)The chromium-bearing kyanite specimen U-158, extracted from a kyanite-eclogite xenolith in a Yakutian kimberlite pipe was studied by transmission electron microscopy TEM. This specimen has an analysed composition (Al-1.989 ...
-
(2003)A monoclinic KAlSi3O8 feldspar Manebach twin boundary was synthesized by diffusion bonding and examined using high-resolution transmission electron microscopy. The sharp (001) twin boundary is straight and free of strain. ...
-
(1998)TEM characterization of progressive alteration of igneous biotite to kaolinite throughout a weathered soil profile was carried out to study the mechanisms of the reaction from biotite to kaolinite. A biotite-like phase ...

-
(1996)The surface microtopography of synthetic magnesian calcite overgrowths on calcite powders was imaged on Pt-C replicas by transmission electron microscopy. The overgrowths were precipitated at room temperature under ...
-
(1995)Nuclear explosions represent a useful simulation of meteorite impacts. Stresses of tens of gigapascals are produced during detonation and stress pulses can last 0.1 ms or longer, which is 3-4 orders of magnitude longer ...
-
(2001)Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) observations on a suite of mid-ocean ridge basalts (MORB) reveal abundant interstitial glass, which differs in occurrence and composition from ...
-
(1995)Seismic anomaly structures at the bottom of the lower mantle may be interpreted in terms of large temperature variations based on new laboratory data at very high pressure: (1) sound velocity measurements at mantle pressures ...
-
(1998)Lithospheric temperatures and heat flow densities (HFD) were simulated in the 650 km long SVEKA transect in the central Fennoscandian Shield. The area is characterized by anomalously thick crust (up to 55 km) and lithosphere ...
-
(2006)A synthesis of previous results, which we dub the "standard model," provides a prediction as to how isotope fractionation during sulfate reduction should respond to physiological variables such as specific rate of sulfate ...
-
(2004)A search of possible response in temperature and wind in the atmosphere for nearby earthquakes has been carried out. We have analysed the profiles of temperature and wind obtained by Wind Imaging Interferometer (WINDII) ...
