(2006)Two new quaternary lead oxyhalides, Pb3MoO5Cl2 and Pb3WO5Br2, have been prepared. They are isostructural with the mineral pinalite, Pb3WO5Cl2, and its barium analog. The crystal structure of Pb3MoO5Cl2, has been refined ...
-
(2006)The formation constants of neodymium complexes in sulfate solutions have been determined spectrophotometrically at temperatures of 30-250 °C and a pressure of 100 bars. The dominant species in the solution are NdSO4+ and ...
-
(2006)The opening of oceanic basins constitutes one of the key features of Plate Tectonics because it determines the rifting and displacement of the continental crustal blocks. Although the mechanisms of development of large ...
-
(2006)The Holocene paleogeography of the Laptev Sea eastern shelf is reconstructed based on mollusks, foraminifers, ostracodes, spores and pollen found for the first time. Environmental changes in the course of the postglacial ...
-
(2006)We have studied experimentally the effects of variable Na2O concentrations on the solubility of four metals (Fe, Co, Ni, and Pd) in silicate melts of anorthite-diopside eutectic composition. Experiments were done at fixed ...
-
(2006)The comparative analysis of palynomorphs and plant megafossils (fruits, seeds, twigs, leaves) in the Upper Pleistocene host sediments and materials filling in fossil burrows of gophers, their coprolites included, at the ...
-
(2006)The Dvuyakornaya Formation section in the eastern Crimea is described and subdivided into biostratigraphic units based on ammonites, foraminifers, and ostracodes. The lower part of the formation contains first discovered ...
-
(2006)The evolution of an active continental margin is simulated in two dimensions, using a finite difference thermomechanical code with half-staggered grid and marker-in-cell technique. The effect of mechanical properties, ...
-
(2006)Stratigraphic position of the Oligocene-Miocene (Paleogene-Neogene) boundary in the northern Caucasus and, in this connection, of the Alkun Formation and the Caucasian regional stage in geological sections of Maikop deposits, ...
-
(2006)Paleontological study of Upper Jurassic and Lower Cretaceous sediments recovered by boreholes in the Agan-Vakh and Nadym-Vengapur interfluves clarified environments of their deposition. As is shown, influx of siliciclastic ...
-
TELESEISMIC TOMOGRAPHY REVEALS NO SIGNATURE OF THE DEAD SEA TRANSFORM IN THE UPPER MANTLE STRUCTURE (2006)We present results of a tomographic inversion of teleseismic data recorded at 48 stations of a temporary network which was installed in the area of the Dead Sea Transform (DST) and operated for 1 yr in the framework of the ...
-
(2006)In the basal interval, sedimentary cover of the Arakapas ophiolite massif (southern Cyprus) is composed of metalliferous sediments of the Perapedhi Formation that is divided into three sequences based on diverse radiolarian ...
-
(2006)Foraminifers from Middle-Upper Jurassic and Upper Cretaceous sediments of the Kaliningrad basin located in the southwestern part of the East European platform are studied. During the greater part of the Late Mesozoic, the ...
-
(2006)Trend of climatic changes in geological history of the Earth was determined by gradual decrease in the global surface temperature. Substantial deviations from this trend depended on the prevalent type of volcanism: ...
-
(2006)Based on results of multidisciplinary study, it is shown that locality Cheremukhovo-1 is of a new taphonomic type in the Urals and characterizes interval of geological record formerly unknown for the late Neopleistocene ...
-
(2006)We have used ex situ atomic force microscopy (AFM), scanning tunneling microscopy and spectroscopy (STM/STS) and X-ray photoelectron spectroscopy (XPS) to study the surfaces of natural arsenopyrite samples that were ...
-
(2006)Based on self-consistent thermodynamic approach, we infer the temperature distribution models at 100 to 300 km depth for the upper mantle beneath the Kaapvaal craton from absolute P- and S-wave velocities and geochemical ...
-
(2006)Chivruaiite is a new Ca titanosilicate [orthorhombic, Cmmm, a = 7.17(2), b = 22.98(9), c = 6.94(2) Å, V = 1144.4 Å3, Z = 1], chemically and structurally related to zorite. The mineral is found in three different hydrothermal ...
-
(2006)The reaction FeS2(cr) + 2Ag(cr) = 'FeS'(cr) + Ag2S(cr) was studied by measuring the temperature dependence of the electromotive force (EMF) of the all-solid-state galvanic cell with common gas space:(-) Pt | Ag | AgI | Ag2 ...
-
(2006)A new occurrence of schreyerite, V2Ti3O9, has recently been found in metamorphic rocks of the Sludyanka complex at the southern shore of Lake Baikal, Russia. In contrast to previously known schreyerite lamellae, which are ...
