(1997)For a general use of the frequency-magnitude (FM) relation in seismic risk assessment, we formulate a multi-scale approach that relies on the hypothesis that only the ensemble of events that are geometrically small, compared ...
-
(2005)The coordination environment of Fe(II) has been examined in seven anhydrous ferrosilicate glasses at 298 K and 1 bar using 57Fe Mössbauer, Fe K-edge X-ray near edge structure (XANES), and extended X-ray absorption fine ...
-
(2004)The primary garnet (pyrope-almandine)-omphacite (Cpx 1, 6.5–7wt% Na2O)-sulfide (Fe-Ni-Co mss) assemblage of the two diamondiferous eclogite xenoliths studied (U33/1 and UX/1) experienced two mantle metasomatic events. The ...
-
(2002)Pb isotope analyses using multicollector magnetic sector inductively coupled plasma mass spectrometers (ICP-MS) may potentially be corrected for mass bias, a major source of uncertainty, by assuming that the mass bias for ...
-
(1998)Multicomponent diffusion and convection in molten MgO-Al2O3-SiO2 at 1550°C and 0.5 GPa were examined experimentally in diffusion couples formed around 22.5 (wt%) MgO, 17.5% Al2O3, and 60% SiO2. The diffusion matrix obtained ...

MULTICOMPONENT DIFFUSION AND CONVECTION IN MOLTEN MGO-AL2O3-SIO2 - III. INTERDIFFUSION COEFFICIENTS (1998)Multicomponent diffusion and convection in molten MgO-Al2O3-SiO2 at 1550°C and 0.5 GPa were examined experimentally in diffusion couples formed around 22.5 (wt%) MgO, 17.5% Al2O3, and 60% SiO2. The diffusion matrix obtained ...
-
(1995)Experimental results are presented for eighteen experiments exploring multicomponent chemical-diffusion in basaltic liquids. Experiments were performed in Columbia River Basalt (CRB) composition doped with about 5 wt% SiO2, ...
-
(1995)We have measured the multicomponent diffusion coefficient matrix, D, for silica rich melts in the system K2O-Al2O3-SiO2 between 1100-1600°C in air. Measurements were done in both peraluminous as well as peralkaline ...
-
(2005)This paper presents the results of studying Vendian rock samples collected along the middle coarse of the Dniester River in the Ukrainian territory. The results of their demagnetization revealed seven components of their ...
-
(2002)In this paper, we present the conception of the multidimensional self-affine distribution and show that the multidimensional self-affine distribution possesses the fractal property of scale-invariance under truncation, ...
-
(2001)In this article we propose an advanced technique for detecting low contrast geochemical anomalies using a set of features. There are three principal elements in this technique: (1) a statistical measure of the contrast of ...
-
(2000)In 1995-1998 the Kamchatkan Experimental Seismological Team (KEST), Geophysical Service (GS), Russian Academy of Sciences (RAN) conducted, in cooperation with other research and production organizations, organizational-technical ...
-
(1990)Investigation of the lateral distribution of seismicity has identified a self-similar hierarchical structure in the seismic field. In addition, it has been shown that the clustering of weak earthquake in plan is of predictive ...
-
(2002)This paper reports new data on petrology and geochemistry of gabbroids and quartz monzonites from the multiphase Phenai Mata Intrusive Complex (PMIC). The complex is situated in the northwest of the Deccan Trap Province ...
-
(2001)The Syrostan gabbro-granite pluton is situated immediately to the west of the Main Uralian Fault and exemplifies a multiple series of five intrusive rhythms. Each rhythm characterizes a separate episode of emplacement of ...
-
(2004)The Khaldzan Buregte group of alkaline massifs was formed during seven intrusive phases and is confined to a large dike belt within Early Caledonian island-arc ophiolite and normal granite cutting the ophiolite. The uranium ...
-
(2005)Sedimentary greigite (Fe3S4) is being increasingly implicated as the carrier of late diagenetic remagnetizations in fine-grained marine and terrestrial sediments. We have conducted detailed scanning electron microscope ...
-
(1988)Methane occurrences in the Earth's crust are predominantly of biogenic origin, i.e. their ultimate source is biologically formed organic matter. Methane can also form through inorganic reactions and is consequently termed ...
-
(2002)Low-temperature phase transitions of leonite-type compounds, K2Me2+(SO4)2 · 4H2O (Me = Mg, Mn, Fe), are investigated by temperature dependent measurements of single-crystal X-ray reflection intensities and lattice parameters. ...
-
(2000)The multiple-scales structure of mantle convection remains largely unknown. A 3D model of convection is used to investigate the effect of a viscosity step on the multiple-scales pattern of an infinite Prandtl number ...
