(2000)The distribution of isotopic water molecules, H2O, HDO, and D2O, in vapor and liquid phases in pure water and aqueous solution systems is related to the D/H fractionation factor between liquid and vapor phases, αL-V, and ...

(Федеральное государственное бюджетное образовательное учреждение высшего образования «Уральский государственный горный университет», 2019)Relevance. This work shows the results of mineralogical, petrographic, and geochemical studies of plagioclasites localized among chromite-bearing ultramafic rocks of the Ray-Iz massif (Polar Urals). The spatial confinement ...

(1989)The authors analyzed statistically the distribution of zones of low and high elasticity in the earth's mantle, using as inputs the charts of velocity vS of transverse (S) waves at depths of 50, 150, 350, 550, 570, 1000, ...

(1995)The concentrations of Ni, Cu, Zn, Ga, Ge, and Se in five, fine-grained chondrule rims in the highly unequilibrated CO3 chondrite ALH A77307 (3.0) have been determined for the first time by synchrotron X-ray fluorescence ...
-
(1998)In the Pleistocene-Holocene section of the Baikal deep-water sediments shales are periodically enriched with the siliceous shells of diatomic algae up to nearly pure diatomite. As the terrigenous shale-silty material is ...
-
(2000)Solution 31P NMR spectroscopy has been used for the characterization of different classes of organic and inorganic phosphorus compounds in a number of different marine and lacustrine sediment environments. All samples ...
-
(1994)Experiments have been conducted on the partitioning of noble metals in the presence of an H-O-C-S fluid in a high pressure gas apparatus at 1200-1300°C and 1-4 kbar fluid pressure. The fugacities of oxygen and sulfur, and ...
-
(2001)We have investigated the distribution of photosynthetic pigments (chlorophyll and carotenoids), total organic carbon (TOC), and biogenic silica in the surface sediments throughout Lake Baikal and suggested factors controlling ...

(1997)In situ measurement of the platinum group elements (PGE) and Re by laser ablation-ICPMS allows fractionation patterns to be established between host (kamacite) and Ni-rich exsolved phases (taenite and plessite). Measurements ...
-
(2004)Bacteria and dissolved humic substances are capable of binding significant concentrations of metals in natural environments. Recent advances in understanding bacteria-metal and humic-metal complexation have provided a ...
-
(1988)In this paper we discuss a continental crust section for S waves, based on data not previously used for the purpose. These are observations of waves converted from P into S waves in the lower continental crust (Ps converted ...
-
(1990)Comparison of maps of the distribution of stratiform polymetallic ore deposits with hydrochemical and salt maps shows the almost universal confinement of such deposits both directly to salt-generating basins and to their ...
