-
(2002)Recent data on the Lower Devonian biostratigraphy in the studied regions are generalized. The described terrigenous and carbonate reference sections yield sharply different faunal assemblages. Carbonate sections of Mongolia, ...
-
(2003)The suggested hypothesis is in sympathy with the new concept of astronomical theory of paleoclimate (Bol'shakov and Bol'shakov, 1999) that implies a greater climatic impact of eccentricity fluctuations than it follows from ...
-
(Федеральное государственное бюджетное образовательное учреждение высшего образования «Уральский государственный горный университет», 2018)Relevance of the topic is due to concern of modern civilized society about the negative impact on the ecology of man-made mineral formations of the mining activity. Technogenic ores are represented by sludges, which are ...
-
(2003)The study of Jurassic gastropods from Central Russia revealed three genera met for the first time in the region under discussion, i.e., Teutonica Schröder, 1995, Longaevicerithium gen. nov., and Novoselkella gen. nov. The ...
-
(2002)On the base of the protoconch structure, the subgenus Plicacerithium Gerasimov, 1992, of the genus Procerithium is reconsidered as a separate genus and moved from the family Procerithiidae to the family Epitoniidae. Several ...
-
(1999)О возможности использования термомагнитных параметров для идентификации вулканических пеплов
-
(1999)The real structures of clinotobermorite, tobermorite 9 Å, and tobermorite 11 Å were determined through the application of OD approach, which allowed us to explain their peculiar disorder and polytypic features and to derive ...
-
(American Geophysical Union, 2007)Three-dimensional structural images of the P-wave velocity below the edifice of the great Klyuchevskoy group of volcanoes in central Kamchatka are derived via tomographic inversion. The structures show a distinct low ...
-
(2002)Tomographic travel time inversion of seismic compressional (P) and shear (S) wave data from the long-range deep seismic sounding experiment Fennoscandian Long Range (FENNOLORA) reveals the velocity structure of the crust ...
-
(2002)We develop the method of tomographic inversion, called RR-R scheme, which is based on joint use of teleseismic P or S refracted rays and corresponding PP or SS rays with bounce points located within a study region. This ...
-
(2001)Observed Tertiary palaeolatitudes in central Asia are more southerly (by about 1600 km on average) than those predicted from the Eurasian reference palaeopoles. Subsequent northward displacements of the central Asian ...

TOOTH ENAMEL MINERALIZATION IN UNGULATES: IMPLICATIONS FOR RECOVERING A PRIMARY ISOTOPIC TIME-SERIES (2002)Temporal changes in the carbon and oxygen isotopic composition of an animal are an environmental and behavioral input signal that is recorded into the enamel of developing teeth. In this paper, we evaluate changes in ...
-
(1990)Topaz-rich ongonite varieties given the name of topazites and picnitites have been discovered in recent years. The dikes of the Utulik belt are well known for the high fluorine content of their rocks, which is the result ...
-
(2002)The functional relationship between erosion rate and topography is central to understanding both controls on global sediment flux and the potential for feedback between tectonics, climate, and erosion in shaping topography. ...
-
(1995)Time series of the boundary deformations and the geoid signal of non-steady convection with pressure- and temperature-dependent viscosity are analysed to obtain information on the uncertainty of estimates of the vertical ...
-
(2000)Drainage divides of mountain ranges will shift laterally during asymmetric erosion of the range. Such asymmetric erosion may occur due to differential precipitation on different sides of a range, or because of different ...
-
(2002)We have used sandbox experiments to investigate and to illustrate the effects of topography upon the development of arcuate thrust belts. In experiments where a sand pack shortened and thickened in front of an advancing ...
-
(2004)A map of Moho depth for the Black Sea and its immediate surroundings has been inferred from 3-D gravity modelling, and crustal structure has been clarified. Beneath the basin centre, the thickness of the crystalline layer ...
-
(1998)The topography of the sea floor provides direct, global and robust evidence for a large mass flux through the mantle transition zone over the past few hundred million years. This is incompatible with some recent interpretations ...
-
(2003)In the framework of a series of methodological studies to test the reliability of the reconstruction of the electron density distribution (EDD) by the maximum entropy method (MEM), we have attempted to check the possibilities ...
