(2003)Resources of giant silver ore deposits found in northeastern Russia are comparable to those of the world's largest deposits such as Potosi (Bolivia) and Guanohuato (Mexico). One of them, e.g., the Dukat deposit, is confined ...
-
(1998)New thermodynamic data are presented for the mixing of calcite (CaCO3(s)) and rhodochrosite (MnCO3(s)) to form CaxMn1-xCO3(s) solutions. A reversible equilibrium was achieved between the aqueous solution and the metastable ...
-
(1997)The Gibbs free energies of formation of RuO2, OsO2 and IrO2 have been determined by measuring the chemical potentials of oxygen (μO2) defined by the reactions M + O2 = MO2, where M = Ru, Os. or Ir, using an electrochemical ...
-
(1996)The solubility of a natural hydrothermal kaolinite was measured in buffered alkaline solutions at temperatures ranging from 60 to 170°C. At temperatures below 110°C equilibrium was obtained from undersaturation, while above ...
-
(1999)New experimental data for gibbsite growth on powdered kaolinite and single crystal muscovite and published data for gibbsite growth on gibbsite powders at 80°C in pH3 solutions show that all growth rates obey the same ...
-
(2001)A Givetian rhynchonellid assemblage from the Chernaya Cuba Horizon in southwestern Novaya Zemlya is described. The new species: Eurycolporhynchus krasinensis, Septalaria tisengausensis, and Septalaria alferovi are described ...
-
(2001)The article presents a new Lake Baikal paleoclimate record of biogenic silica for the Brunhes Chron (from 780 ka ago to the present). Correlation of the Lake Baikal record with the marine oxygen isotope record shows that ...
-
(1996)Diamictites, many of glacial origin, are globally distributed in the Neoproterozoic. Recently, two relatively thin diamictites in the Maikhan Uul Member at the base of the Neoproterozoic Tsagaan Oloom Formation from the ...
-
(2002)Environmental conditions and productivity changes in the southeastern Okhotsk Sea have been reconstructed for the last 20 ka using planktonic and benthic foraminiferal oxygen isotope records and calcium carbonate, organic ...
-
(2002)Glacial isostatic adjustment data are commonly used to invert for the radial viscosity structure of the mantle. However, the effects of lateral variations in mantle viscosity in such inversions are not yet accounted for. ...
-
(1988)Recent surveys of bottom sediments in the Barents Sea revealed deposits of an unusual kind, whose genesis was attributed to processes of submarine slumping and suspension flow. The clayey sediments classified as suspension-flow ...
-
(2003)The waters of modern Lake Baikal circulate well and maintain oxic conditions for the entire lake in spite of its great depth. Past oxic/anoxic conditions in the water column are not known. Because recon- struction of ...
-
(2002)Sr and Nd isotopic compositions of Arctic marine sediments characterize changes of sediment source regions and trace shelf–ocean particle pathways during glacial–interglacial transitions in the eastern Arctic Ocean. In the ...
-
(2004)The quaternary chronology and distribution of glaciations through the last million years is described. The scheme of main paleogeographical events is based on multidisciplinary studies (geological, paleontological, ...
-
(2002)Glacierised areas present an ideal environment in which to study water-rock interaction, since chemical weathering rates are high and anthropogenic impacts are often minimal. Detailed investigations of meltwater quality ...
-
(2004)Over the recent years, while executing the geological mapping of the Lithuanian territory at a scale of 1:50 000, attention have been given to kame terraces adjoining the recessional marginal ridges left by glacier lobes ...
-
(2004)Field and archival data have been used in compiling the Glaciotectonic Map of Estonia. Two principal types of glaciotectonic deforma- tions shown on this are discussed here: dislocations of rigid bedrock, and soft bed ...
-
(2001)Molecular dynamics (MD) simulation provides a unique window into the dynamics of amorphous silicates of geochemical importance. Of special interest are theories of the glass transition and viscosity when an equilibrium ...
-
(2001)Nakhla augite and olivine grains commonly contain glass-bearing inclusions. In contrast to olivines, augites host only one type of multiphase inclusions which consists of euhedral to subhedral augite, Ti-magnetite and ...
-
(1995)Peridotitic xenoliths from melanephelinites of Sal Island, Cape Verde Archipelago, have a compositional range from moderately depleted Iherzolites to refractory harzburgites. Most xenoliths have protogranular textures but ...
