(2004)Mud-bottom hollows are depressions on the bog surface where Sphagnum mosses have died and peat accumulation is retarded or even replaced with loss by oxidation. Results of measurements carried out at MAnnikjArve Bog, central ...
-
(2003)One of the outstanding problems of palaeoclimate reconstruction from physico-chemical properties of terrigenous deep-sea sediments stems from the fact that most basin fills are mixtures of sediment populations derived from ...
-
(2001)A detailed characterisation of the subsurface using high-resolution multi-component seismic data requires additional processing. We adapted a frequency-domain wavefield separation method and applied it in an iterative way ...
-
(2002)The multi-criteria calibration procedure MOCOM-UA was used to evaluate the validity of a physically based precipitation-runoff model by forcing the model to simulate several observed system responses simultaneously. The ...
-
(2001)In this paper we present and discuss the frequency-dependent behaviour of the acoustic characteristics of methane hydrate-bearing sediments in Lake Baikal, Siberia. Five different types of seismic sources (airgun-array, ...
-
(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 ...
