(2002)Oceanic contributions to the annual and semi-annual wobble of polar motion have been evaluated by Wünsch (Wünsch, J., 2000. Oceanic influence on the annual polar motion. J. Geodynamics 30, 389–399) using three different ...
-
(2001)The Precambrian-Cambrian (PC-C) boundary separates fossils representing two discrete evolutionary phases: the Neoproterozoic soft-bodied Ediacarian biotas and Cambrian small shelly faunas. The biological discontinuity is ...
-
(1989)In East Kamchatka, Cretaceous oceanic rocks are known on the Cape Kamchatskiy peninsula and in the melange zones of the East Ranges. The authors' investigations in 1985-1987 revealed oceanic rocks in the eastern part of ...
-
(2003)We propose a unifying explanation for the four major icehouses during the past c.620 million years: earliest Oligocene to Present; early Carboniferous to early Permian; late Ordovician and late Vendian (the ‘snowball Earth’) ...
-
(2000)Oceanic contributions to the seasonal wobbles of polar motion are evaluated using three different ocean circulation models: (a) the Parallel Ocean Climate Model; mass term only, i.e. tensor of inertia changes; (b) the model ...
-
(2000)Statistical study of basalts from mid-ocean ridges differing in spreading rate shows that two main petrochemical groups of basalts, N-MORB and ferrobasalts, are zonally distributed along ang across their crest. Ferrobasalts ...
-
(2004)An Earth system model of intermediate complexity, CLIMBER-2, is used to simulate the oxygen-18 content of the water masses (H182O) in the oceans. Firstly, we forced CLIMBER-2 with the fluxes from the atmospheric general ...
-
(1998)Field studies combined with chemical and isotope data indicate that the Kostomuksha greenstone belt in the NW Baltic Shield consists of two lithotectonic terranes, one mafic igneous and the other sedimentary, separated by ...
-
(2003)The geologic structure, geochemistry, lithology, and paleontology of the Late Cambrian-Early Ordovician volcanosedimentary Zasur'ya Group in Gorny Altai are considered. Its geochemical parameters, lithologic features, and ...
-
(2001)Isotropic shear-wave velocities from the Ekström/Dziewonski S20 global tomographic model and residual `crust-free' gravity are used to determine density-velocity relations for various mantle layers by inversion. The residual ...
-
(1997)A new synthesis of the Black Sea oceanography is presented, primarily based on studies carried out in the southern Black Sea, as well as on some recent work covering the entire basin, obtained in a new era of increasing ...
-
(2003)The distributions of Al3+/Mg2+ and Al3+/ Fe3+ were studied in the octahedral sheet of illites and smectites. Cation exchange interaction parameters J i , as first, second, third and fourth neighbours were calculated by ...
-
(2002)We use drainage patterns, geological markers and geomorphological features to determine a right-lateral offset of ∼50 km, and possibly as much as ∼70 km, on the Main Recent Fault in NW Iran. This fault trends NW–SE and ...
-
(2001)The OH content of four rutile and two cassiterite single-crystals was studied by nuclear reaction analysis (NRA) and by polarised FTIR microspectroscopy. The OH absorption bands of both minerals are centered around 3300 ...
-
(2004)Two infrared (IR) spectral types are discerned in cassiterites with OH defect concentrations ranging from several wt. ppm H2O in synthetic melt-grown samples up to 0.017 wt.% in natural samples of hydrothermal origin. ...
-
(2003)The incorporation of hydrogen into the coesite structure was investigated at pressures ranging from 4.0–9.0 GPa and temperatures from 750–1300 °C using Al and B doped SiO2 starting materials. The spectra show four sharp ...
-
(2004)Oil- and gas-bearing basins of the World Ocean spreading to the continental shelf and foothill are considered. Large hydrocarbon resources, including oil pools have been discovered in the deep-water basins. The basins are ...
-
(2003)Resistivity sounding technology is applied to the characterization of oil polluted areas. It includes the analysis of the model of oil pollution as a low resistivity zone, the field study technique, advanced data processing, ...
-
(2001)The chemical composition of oil shales from caldera lakes facies, as well as the carbon and oxygen isotope composition of rock-forming carbonates and sulfur isotope composition of pyrite from fine veinlets have been studied. ...
-
(2003)The 2.45-Ga fluvial quartz arenites and conglomerates of the Matinenda Formation at Elliot Lake, Canada, contain evidence for two episodes of oil migration with entrapment of oil-bearing fluid inclusions. The first episode ...
