(1998)Soret diffusion rise times were observed and resolved for Fe-Ni-S-P melts at 10 kbar in thermal gradients between 1300 and 1450°C. A steady-state separation of S-rich components to the hot end of the ~2 mm long liquid ...
-
(2006)Our knowledge of the degassing pattern of sulphur, chlorine and fluorine during ascent and eruption of basaltic magmas is still fragmental and mainly limited to water-poor basalts. Here we model and discuss the pressure-related ...
-
(1999)A new genus Sakhatoides is established based on Upper Induan material from Northeastern Asia. The morphogenesis of the major structural elements of its shell and the phylogeny of the new genus are studied. Two species of ...
-
(2004)An original concept of salinization of coals at the peat bog generation stage is substantiated on the basis of on new data. The distribution of saline coals within coal and hydrocarbon basins has been revealed to be wider ...
-
(2006)In coastal areas, groundwater and aquifer systems are easily prone to pollution and contamination. Moreover, sea level rises also threaten the viability of many coastal zones and small islands. In the Shiroishi lowland ...
-
(2006)The need for more agricultural or residential land has encouraged reclamation at the coastal areas of Korea since 1200 ad (approximately). The groundwaters of these reclaimed areas could be expected to reveal hydrogeochemical ...
-
(2006)Laboratory experiments have demonstrated that supercritical water has extremely low solubility for normal sea salts. This fact opens up the possibility for the precipitation of salt from seawater that circulates in faults ...
-
(2003)Fluids in the deep-seated zones (3.5–4.5 km) of active geothermal zones are known to have increased salinity and acidity that can enhance interaction with surrounding porous rocks. A possible mechanism for brine generation ...
-
(1996)The global budget for marine uranium demands another geochemical sink other than deep-sea systems, and the coastal environment may host some or all of this missing sink. In a previous paper (Sarin and Church, 1994), we ...
-
(2003)A 3D backstripping approach considering salt flow as a consequence of spatially changing overburden load distribution, isostatic rebound and sedimentary compaction for each backstripping step is used to reconstruct the ...
-
(2003)Pricaspian basin geology is reviewed in the light of 500,000 km of seismic profiles and several thousand wells. We focus on how hydrocarbons from three sources accumulated in relation to the 1800 salt structures in a basin ...
-
(2000)A 2.0 molal solution of sodium acetate and 0.1, 0.5, and 1.0 molal solutions of calcium acetate were investigated by Raman spectroscopy from 22 to 400°C at 1000 and 2000 bar. Experiments were performed in a special ...
-
(2001)Post-deposition U uptake by bones and teeth is the most significant source of inaccuracy in both U-series and ESR dating. In most cases assumptions about the form of U uptake are required to calculate a date. We have been ...
-
(2001)Adequate knowledge of soil moisture storage as well as evaporation and transpiration at the land surface is essential to the understanding and prediction of the reciprocal influences between land surface processes and ...
-
(2006)The volcanic history of Santo Antao, NW Cape Verde Islands, includes the eruption of basanite–phonolite series magmas between 7·5 and 0·3?Ma and (melilite) nephelinite–phonolite series magmas from 0·7 to 0·1?Ma. The most ...
-
(2001)We have used granular materials to model the development of thrust wedges, where migrating pore fluids assisted in the formation of detachments. The governing equations yield practical scales for linear dimensions, stresses ...
-
(1994)Sapphirine occurs with humite-group minerals and forsterite in Precambrian amphibole-facies rocks at Kuhi-lal, SW Pamir Mountains, Tajikistan, a locality also for talc+kyanite ± magnesiohornblende whiteschist. Most of these ...
-
(2004)Calculation of gravity from satellite altimetry data (hereafter, satellite determinations) faces the problem of accuracy of the results obtained. The uncertainty of satellite determinations was constantly assessed both in ...
-
(1998)The principles of the technique of Satellite Laser Ranging are briefly explained and the current status and outlook for further development are described. Results for the application of this technique in the WEGENER program ...
-
(2006)Water erosion creates negative impacts on agricultural production, infrastructure, and water quality across the world. Regional-scale water erosion assessment is important, but limited by data availability and quality. ...
