-
(2004)High-resolution transmission electron microscopy (HRTEM) affords a close look at the complex structures and intergrowths of the serpentine minerals. All contain alternating sheets of cations in tetrahedral and octahedral ...
-
(2004)Serpentinitic mélanges containing eclogites, blueschists, and jadeitic rocks have been studied within the following foldbelts: Borus (West Sayan), Chagan-Uzun (Gorny Altai), Chara (East Kazakhstan), Kokchetav (North ...
-
(2003)The lithofacies characterization of beds in the Serpukhovian Stage stratotype, the Zabor'e Quarry site near Serpukhov, is presented. Ten members, boundaries of which do not coincide with those of local subdivisions formerly ...
-
(2004)Muratovka Paleokarst at the top of Venevian and Dashkovka Paleosol at the top of Steshevian are described in Zaborje Quarry. The Dashkovka profile is classified as a durisol with near-surface calcrete hardpan. The pre-Moscovian ...
-
(1998)In order to evaluate the mechanism of production of unusual high-Mg andesite (HMA) magmas, Pb–Nd–Sr isotopic compositions were determined for HMAs and basalts from the Miocene Setouchi volcanic belt in the SW Japan arc. ...
-
(2002)Settling velocities and entrainment thresholds of biogenic sedimentary particles, under unidirectional flow conditions, are derived on the basis of settling tower and laboratory flume experiments. Material consisting ...
-
(PANGAEA, 2019-04-03)Here we used a well-evaluated process-based ecosystem model, Dynamic Land Ecosystem Model (DLEM), to simulate the spatial and temporal changes of net ecosystem productivity (NEP) in response to climate variability and ...

(PANGAEA, 1983-03-21)
-
(2001)The study of horned dinosaurs housed at the Paleontological Institute of the Russian Academy of Sciences revealed 19 structural parameters of the postcranial skeleton that distinguish males from females. Based on comparisons ...
-
(1998)An updated analysis of the global paleomagnetic database shows that the frequency distributions of paleomagnetic inclinations for the Cenozoic and Mesozoic eras (younger than 250 Ma) are compatible with a random geographical ...
-
(1986)The structure and seismicity of the Moon is very different from that of the Earth. One point of similarity is that statistics of seismic energy release in both bodies are dominated by the largest shallow-focus events. This ...
-
(2001)Slab detachment (or breakoff) has been proposed as a cause of temperature-related processes associated with subduction, such as postcollisional magmatism, mineralization, and metamorphism. In this study, we quantitatively ...

SHALLOW STRATIGRAPHIC DRILLING APPLIED IN HYDROCARBON EXPLORATION OF THE NORDKAPP BASIN, BARENTS SEA (2002)The Nordkapp Basin is a Late Palaeozoic rift basin characterised by numerous salt diapirs. The salt was deposited in the Late Carboniferous-Early Permian and has been remobilised several times. Upper Palaeozoic and Mesozoic ...
-
(2004)Leg 144 (1995) of the Ocean Drilling Program recovered basalts and volcaniclastic material from the volcanic basement of several guyots in the northwest Pacific, including MIT Guyot in site 878. Tectonic reconstruction ...
-
(2004)Quite unusual shapeless dark diamonds, yakutites, which are widespread in placers in the north of the Siberian Platform, were studied by methods of analytical scanning electron microscopy and analytical transmission electron ...
-
SHARP DECREASES IN THE DENSITY OF THE SPORADIC ES LAYER IN THE IONOSPHERE AS AN EARTHQUAKE PRECURSOR (1989)Seismically generated ionospheric phenomena have been discussed in several publications; the primary focus has been on the F layer. Effects in the E layer have been reported, but there has been no detailed analysis of them. ...
-
(2004)Synthetic forsterite samples were shear-deformed at 11 GPa, 1400°C in the multianvil apparatus. The deformation microstructures have been characterised by SEM, EBSD, X-ray diffraction peak broadening and strain anisotropy ...
-
(2004)The shear viscosity of 66 liquids in the systems CaO-Al2O3-SiO2 (CAS) and MgO-Al2O3-SiO2 (MAS) have been measured in the ranges 1–104 Pa s and 108–1012 Pa s. Liquids belong to series, nominally at 50, 67, and 75 mol.% SiO2, ...
-
(2004)Shear waves that traverse the lowermost mantle exhibit polarization anomalies and waveform complexities that indicate the presence of complex velocity structure above the core-mantle boundary. Synthetic seismograms for ...
-
(2003)Shear wave splitting measurements in South Kamchatka during the 3-year period (1996–1998) in which the Kronotsky Earthquake (M=7.7, December 5, 1997) occurred are used to determine anisotropic parameters of the subduction ...
