-
(2005)The laser 40Ar/39Ar dating technique has been applied to five Luna 16 basalt fragments and one impact glass, and nine Luna 24 basalt fragments and one breccia. The textures of these basalts are fine-grained ophitic and ...
-
(2002)In terms of their detailed volcanology and facies architecture, continental flood basalts and associated volcanic rifted margins reveal important information to help our understanding of their evolution. Mafic volcanism, ...
-
(2001)Volcano-tectonic depressions and domes from the North-Kamchatka-Koryakskii and Central Kamchatka volcanic belts are described in terms of their structure, geophysical expression, and mineralization.
-
(1989)The authors have developed a method of deep geoelectric investigation using the 800-kV Volgograd-Donbass DC power line and have developed a set of programs for automated data processing and preliminary interpretation. Area ...
-
(2001)The volume change associated with dehydration melting has been investigated experimentally in muscovite and biotite-bearing assemblages because it is a possible driving force for melt segregation during orogenesis. Experiments ...
-
(1994)Predictions of molar volume, excess molar volume, and isochoric P-T trajectories from thirteen published equations of state are compared with one another and with preliminary volumetric data for CO2-CH4-N2 fluids at 200°C ...
-
(1999)An instrument and results of experiments on dynamical phenomena in gravitation are described. A preliminary interpretation is presented, and some inferences are offered concerning an analogy between dynamic gravitation and ...
-
(2001)The crystal structure of the mineral vulcanite, CuTe [a = 3.155(1), b = 4.092(1), c = 6.956(1) A; Z = 2; space group: Pmmn, No. 59] exhibits a pronounced layer structure with Te-Te distances between the CuTe layers of ...
-
(2000)The decay of the short-lived isotope 182Hf to the isotope 182W early in solar system history provides clues to the origin and evolution of the Earth and Moon. Current time-scales for the formation of proto-planets in the ...
-
(1997)A new hydrous silicate phase with formula Mg1.71Fe0.177Al0.01Si0.965H0.332O4 has been synthesized at 1400°C and 17.5 GPa from a hydrous iron-rich mantle peridotite composition. The space group is Imma and unit cell parametersa ...
-
(2005)The crystal structure of the rare mineral wakabayashilite was solved by direct methods using intensity data collected from a twinned crystal. This study revealed that, in spite of the strong hexagonal pseudosymmetry, the ...
-
(2001)Products of the hydrothermal alteration of rocks and vertical zonality at the Kanimansur silver-polymetallic deposit (Tadjikistan) have been studied. On the basis of these studies, physicocochemical conditions of metasomatism ...
-
(2002)The problem of the existence of a Tethys circumglobal current (TCC) in the Late Cretaceous continental geometry (Campanian) is addressed. Within an ocean model which is expected to strongly overestimate the wind-driven TCC ...
-
(2003)Crystals of natron, Na2CO3·10H2O, were grown by slow evaporation of a saturated sodium carbonate solution at room temperature. A single-crystal fragment was measured on a CCD X-ray four-circle diffractometer at 110, 270 ...
-
(2003)Magma degassing may occur either with no significant gas escape from the magma column, which corresponds with typical Plinian type eruptions, or with gas loss, which corresponds with typical effusive (dome-building) ...
-
(2000)A review of published and newly measured densities for 40 hydrous silicate glasses indicates that the room-temperature partial molar volume of water is 12.0 ± 0.5 cm3/mol. This value holds for simple or mineral compositions ...
-
(2000)To determine the effect of water on the rheology of depolymerized melts, we have measured the viscosity of two series of hydrated synthetic aluminosilicate melts analogous in bulk polymerization to tephritic and basanitic ...
-
(2003)The kinetics of hydrogenation of dry synthetic forsterite single crystals was determined by performing experiments under hydrothermal conditions. The experiments were performed at 1.5 GPa, 1000 °C for 3 h in a piston-cylinder ...
-
(2004)The dehydration rate of hydrous rhyolitic glasses at 475-875 °C was measured by in situ infrared (IR) spectroscopy in order to determine the diffusion coefficient of water in rhyolitic glasses. The IR spectra of glass thin ...
-
(2002)Hartree-Fock and B3LYP NMR calculations were performed at the 6-311+G(2df,p) level on cluster models representing albite glasses using B3LYP/6 to 31G* optimized geometries. Calculation results on several well-known crystalline ...
