-
(1965)The southern part of the Kuril Islands is typical of an island arc. The structure of the earth's crust in that region has been well studied by seismic sounding. The present paper gives a short synthesis of data about the ...
-
UPPER MANTLE STRUCTURE BELOW THE DALDYN-ALAKITSK KIMBERLITE FIELD BY NUCLEAR EXPLOSION SEISMOGRAMS (2001)It was established on the basis of seismograms of nuclear explosions that the upper mantle up to the depth of 410 km is characterized by chemical differentiation, which occurs as alternating layers with low and high body ...
-
(2003)A new teleseismic tomography approach (RR-R scheme), based on joint processing of differential travel times of P or S refracted rays and corresponding PP or SS rays with bounce points in a selected area, allows three-dimensional ...
-
(1999)Forward numerical models are used to investigate the effect of deformation regime on the development of olivine lattice-preferred orientations (LPO) and associated seismic anisotropy within continental deformation zones. ...
-
(2000)The Upper Mesozoic strate of the Korean Peninsula are subdivisible into three unconformity-bounded units, and they developed time-transgressively toward the Pacific. The lower unit straddling the Jurassic-Cretaceous boundary ...
-
(2004)Late Oligocene basins were very unusual in terms of sedimentation. The most remarkable example is the early Kalmykian basin that was characterized by the drastic morphological differentiation and deposition of substantially ...
-
(2004)Upper Oligocene sediments of the Eastern Paratethys are distinguished in the Maikop Group owing to several characteristic features. They form a thick (1000–1200 m) sequence with specific composition and structure in different ...
-
(2004)The structure of bone detritus and iron sulfide deposits is scrutinized based on the abundant analytical data on their component composition and metal potential. It is shown that maximal concentrations of bone detritus and ...
-
(2004)The Upper Ordovician (uppermost Caradoc-Ashgill) section of western Estonia consists of a series of seven open-shelf carbonate sequences. Depositional facies grade laterally through a series of shelf-to-basin facies belts: ...
-
(2003)The analyzed materials obtained by editorial preparation of a new map series, scale 1 : 1 000 000, and generalization of earlier data show that, contrary to prevailing opinions, the Middle to Upper Carboniferous deposits ...
-
(2002)The Tunka rift valley extending from the SW termination of Lake Baikal by 200 km westward represents a series of large and smaller troughs separated by subordinate elevations. Inversely uplifted bedrock exposures exhibit ...
-
(1990)At the present time the boundary between the Pliocene and the Pleistocene on Sakhalin is drawn on the basis of the angular unconformity observed between the deposits of these epochs or in those parts of the section where ...
-
(2004)Deep seismic experiments on continental lithosphere generally reveal marked reflectivity from structures in the crust and a significant decrease in reflectivity from the upper mantle. However, reflected and refracted energy ...
-
(2003)When numerical models are used for modeling large-scale flow and transport processes in the subsurface, upscaling is generally needed to determine large-scale hydraulic properties from small-scale measurements. This study ...
-
(1999)The investigation of the Cu2+ uptake by the calcium carbonate minerals vaterite and calcite with continuous wave and pulse electron paramagnetic resonance (EPR) yields information on a molecular scale about the relevant ...

UPTAKE OF DISSOLVED CD BY BIOGENIC AND ABIOGENIC ARAGONITE: A COMPARISON WITH SORPTION ONTO CALCITE (2003)The uptake of Cd2+ by aragonite and calcite is investigated by combining macroscopic measurements with some qualitative sorption experiments performed in a hydrogel medium. Both biogenic and abiogenic aragonites were studied ...
-
(2003)Marine Fe-Mn oxyhydroxide crusts form by precipitation of dissolved components from seawater. Three hydrogenetic crust samples (one phosphatized) and two hydrothermal Mn-oxide samples were subjected to a sequential-leaching ...
-
(2003)We substantiate theoretically the recognition of the Paleozoic-Early Mesozoic Ural-Paikhoi-Novaya Zemlya fold belt as Uralides not analogous to Hercynides (Variscides) and the preceding Late Vendian Timan folded structures ...
