(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, ...
-
(Федеральное государственное бюджетное учреждение науки Геофизический центр Российской академии наук, 2015)Many scientists around the world have reported the occurrence of atmospheric anomalies prior to earthquakes. According to the Lithosphere-Atmosphere-Ionosphere Coupling (LAIC) model, the thermal flux results in temperature ...
-
(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, ...
