(Общество с ограниченной ответственностью «Георесурсы», 2018)The work is devoted to the effectiveness analysis of thermochemical method of intensifying the hydrocarbons inflow using binary mixtures based on ammonium nitrate in the development of lowpermeability reservoirs of ...
-
(1999)We report H and C contents and δD and δ13C values of apatites from 15 alkaline intrusive complexes ranging in age from 110 Ma to 2.6 Ga. Sampling focused on carbonatites, but included silicate rocks as well.Heating at ...
-
(1999)The intensity of hydrogen and methane generation in the course of serpentinization was calculated by the method of the thermodynamic modeling of the interaction of sea water with mantle peridotite in the temperature range ...
-
(2005)The solubility and incorporation mechanisms of H and various trivalent and divalent cations in synthetic rutile have been investigated. Experiments performed using different bulk Fe2O3 contents demonstrate that Fe3+ ...
-
(1998)Hydrogen and oxygen isotope fractionation factors between brucite and aqueous NaCl solutions (1000lnαbr-sw) have been calibrated by experiment from 250 to 450°C at 0.5 Kb. For D/H fractionation, 1000lnα br-sw values are ...
-
(2004)The hydroxy groups of the crystal lattice of dioctahedral 2:1 phyllosilicates were investigated by means of quantum-mechanical calculation. The standard Kohn-Sham self-consistent density functional theory (DFT) method was ...
-
(2003)Ikaite is a metastable hexahydrate of calcium carbonate, forming in aqueous conditions near freezing conditions. Neutron powder diffraction data of synthetic deuterated ikaite, collected at seven temperatures from 4 to 270 ...
-
(2003)Hydrogen diffusion coefficients in natural orthopyroxenes and synthetic enstatite were determined by dehydration and hydration experiments at 700 and 900 °C. In natural Opx (approximately En90Fs10) small but significant ...
-
(2000)Several of the supposedly anhydrous major minerals of the upper mantle have been shown to regularly contain small amounts of hydrogen. The concentrations measured in the most important minerals obtained from mantle xenoliths ...
-
HYDROGEN IN SOME NATURAL GARNETS STUDIED BY NUCLEAR REACTION ANALYSIS AND VIBRATIONAL SPECTROSCOPY (2003)A suite of 11 gem-quality, optically completely clear garnet crystals with a broad variety of compositions in the space of the end members pyrope-almandine-spessartine-grossular-andradite-goldmanite were analyzed for trace ...
-
(2001)The mechanisms of exchange of hydrogen between the deep interior and surface of Earth, as well as the means of retention and possible abundance of hydro-gen deep within the Earth, are examined. The uppermost several hundred ...
-
(2001)Bulk and step-heating hydrogen isotope measurements of glassy and vesicular samples from three young rhyolite lavas demonstrate for the first time that magmatic H2O can be distinguished from meteoric H2O added during ...
-
(2004)We present new hydrogen isotope data for separated matrix, hydrated chondrules, and other hydrated coarse silicate fragments from nine carbonaceous chondrites. These data were generated using a micro-analytical method ...
-
(1998)We have investigated the changes in the ratio of stable isotopes of hydrogen when cellulose is subjected to thermal stress at the high temperatures of 180°C and 200°C, respectively. The thermal stress caused deuterium ...
