-
(2004)The clay fraction of the sedimentary succession beneath the Mahakam Delta (eastern Kalimantan, Indonesia) consists mainly of mixed-layer illite-smectite, with minor amounts of kaolinite and/or dickite, discrete detrital ...
-
(1988)The need to plan water protection measures in the 30-km accident zone around the Chernobyl nuclear power plant [1] has made it necessary to forecast second radioactive pollution of rivers produced by the leaching and washoff ...
-
(2001)A carbon and sulfur isotope mass balance model has been constructed for calculating the variation of atmospheric O2 over Phanerozoic time. In order to obtain realistic O2 levels, rapid sediment recycling and O2-dependent ...
-
(2002)We present a general, flexible, and fast neural network approach to the modeling of a conditional distribution of a discrete random variable, given a continuous or discrete random vector. Although many more applications ...
-
(2002)Electromagnetic field anomalies provide a means to estimate the confined water pressure changes through electrokinetic effects in the preparatory stages of an earthquake occurrence process. Typical shorter period pulse-like ...
-
(2004)Numerical modeling is a powerful tool for investigating the formation of large impact craters but is one that must be validated with observational evidence. Quantitative analysis of damage and deformation in the target ...
-
(1998)Interaction between a tin-bearing greisenizing fluid and a leucogranitic rock was modeled in order to evaluate the possible role of alteration induced changes in fluid chemistry in cassiterite deposition. The interaction ...
-
MODELING HETEROGENEOUS STRETCHING DURING EPISODIC OR STEADY RIFTING OF THE CONTINENTAL LITHOSPHERE (2001)The geometry of brittle-ductile extension and modes of normal faulting during steady or episodic rifting of the continental lithosphere are investigated by analogue modeling using the centrifuge technique. We use a frictional ...
-
(2002)We have developed a model to simulate the formation and evolution of hydraulic fractures. The model relies on a discrete spring network representation of the fracturing media and a continuum description of the fluid pressure ...
-
(2001)Pore-water profiles of CO2, pH, Ca2+ and O2 in situ concentrations were measured at two stations on the upper continental slope off Gabon. The present study evaluates these measurements concerning their implications for ...
-
(2001)Dioctahedral 2:1 phyllosilicates with different interlayer charge have been studied theoretically by using transferable empirical interatomic potentials. The crystal structures of pyrophyllite, muscovite, margarite, ...
-
(2002)Cubic equations of state (EOS) are widely used to represent the phase behavior of gas-oil-systems, whereas different types of models have traditionally been used to describe gas solubility in aqueous mixtures. Since formation ...
-
(2004)The chemisorption of Au on carbonaceous matter (CM) was studied at 20-500°C and 1 kbar in water and in 1 m NaCl with application to the formation of gold mineralization in carbon-bearing complexes. The Au concentration was ...
-
(2001)Lecithin liposomes were used to experimentally model oxidative polymerization transformations in the lipid substance, a probable kerogen source. The resulting model kerogen was characterized as structurally close to real ...
-
MODELING OF LARGE FAULTS IN ZONES OF LITHOSPHERIC EXTENSION AND NUMERICAL CONSTRAINTS ON DEFORMATION (2001)A similarity-based physical model of faulting in zones of lithospheric extension simulated formation of fault systems in extended viscoelastic ductile material and their gradual coalescence into a single major suture. This ...
-
(2004)The nonlinear passage of the acoustic waves through the lithosphere to the surface of the Earth during earthquakes and strong underground explosions is analyzed in this report. The underlying mechanism for this is the ...
-
(2002)The analytical formulation of the theories of nutation and wobble reveals the combinations of basic Earth parameters that govern the nutation-wobble response of the Earth to gravitational (tidal) forcing by heavenly bodies ...
-
(2001)High-F silicic (HS) rocks have some characteristic geochemical features. The REE distribution, for exam-ple, is characterized by approximately equal chondrite-normalized abundances of LREE and HREE (equal-arm distribution) ...
-
(2001)A model for seismo-electromagnetic (SEM) phenomena is described. The electromagnetic signals generated by mechanical disturbances in the earth's crust have been calculated and compared with reported seismo-electromagnetic ...
