-
(2002)Both the density of terrestrial hot spots and their associated buoyancy flux show non-random distributions. These distributions are bimodal and symmetric about the equator with maxima occurring between 20 and 30° latitude. ...
-
(2002)The currently adopted rainfall-based design flood estimation techniques, for example the Design Event Approach, do not account for the probabilistic nature of the key variables except for the rainfall depth. This arbitrary ...
-
(1996)The thermodynamic and structural properties of H2OCO2 mixtures along two supercritical isotherms at 773.15 and 1073.15 K in the pressure range from 0.2 to 30 kbar have been investigated by the NVT and NPT Monte Carlo ...
-
(2003)The ordering of Al3+, Fe3+, and Mg2+ cations along the octahedral sheet in dioctahedral 2:1 phyllosilicates was studied theoretically. The distribution of Fe3+/Mg2+ was studied in the octahedral sheet and is compared with ...
-
(2003)In this study, a Monte Carlo simulation method is applied to study groundwater flow and solute transport in heterogeneous, dual-porosity media. Both the hydraulic conductivity and the interregional mass diffusion rate are ...
-
(1989)The authors have discovered in the Katanga-Tetere interfluve extensive reserves of mordenite, produced by post-sedimentary transformation of ashy tuffs of intermediate composition. The particle-size distribution of the ash ...
-
(2002)Examines the chemical distinction between epidote and clinozoisite. Efficacy of optical mineralogy for chemical analysis; Contribution of Daniel E. Kile, geologists, on the definition of chemical composition of the minerals; ...
-
(2003)The morphology, systematics, and ecology of bivalves are discussed. Changes in the taxonomic composition and morphogenesis of this group in the Phanerozoic are traced. Several ethological-trophic groups are characterized, ...
-
(2002)The morphogenesis and homologies of the major skeletal structures of crinoids and similar Early Paleozoic echinoderms are analyzed on the basis of comparative morphological analysis. The study of symmetry and asymmetry in ...
-
(2001)Microorganisms of the Baikal Rift are of peculiar interest owing to their isolated evolution and the ancient origin of Lake Baikal. Samples of rocks sedimented at various stages of the Baikal Rift development have been ...
-
(2004)Morphological and histological aspects of conodont element regeneration are considered on the basis of material from the Late Devonian and Early Carboniferous. It is shown that the regeneration mechanism of conodonts ...
-
(2002)We relate reverse fault scarp morphology formed by several earthquake dislocations to the average deformation rate, using a morphological dating model based on a diffusion analogue of erosion. Our scarp degradation model ...
-
(2001)The air photographs of the craters of Kamchatkan volcanoes, collected during the last three decades, were decoded, photogrammetrically processed, and interpreted to recognize the features and phenomena which can be used ...
-
(2003)Leaves of "Platanus" raynoldsii Newberry were widespread in the floras of the Northern Hemisphere predominantly in the Paleocene, and were also present in the Maastrichtian and Early Eocene. As in the majority of the ...
-
(1990)The melt impactites (tagamites) of the Boltysh astrobleme (in the Ukraine) form a body more than 200 m thick (the diameter of the structure is approximately 24 km). The rocks of the target area consist of Precabrian granites ...
-
(2004)The qualitative and quantitative analysis of the holomorphic folding morphology in the central segment of the South Tien Shan revealed its heterogeneity in the Paleozoic rock sequences. Against the background of the gradual ...
-
(2002)Neocassandra mica Daniltshenko, 1968 from the Late Paleocene of Turkmenistan is revised and assigned to the order Aulopiformes. However, it substantially differs from all members of the order in the following characters: ...
-
(2001)The systematic position of a peculiar group of Angaran gymnosperms usually treated as "cordaites" is discussed. The systematics of these plants related to coniferophytes remains uncertain because of their extreme peculiarity. ...
-
(2003)The morphology and systematic position of Sphenophyllum biarmicum Zalessky are discussed. "Gangamopteris" fimbriata Zalessky, "G." tenuinervis Zalessky, and Sphenophyllum comiense Tschirkova are considered to be synonyms ...
