-
(2001)We report the results of a comparative thermomagnetic investigation on natural volcanic samples. Susceptibility vs temperature (k–T curves), induced magnetization vs temperature and remanent (saturated) magnetization vs ...
-
(2002)Increasing attention has been paid to the use of non-Gaussian distributions as models of heterogeneity in sedimentary formations in recent years. In particular, the Levy-stable distribution has been shown to be a useful ...
-
(2001)Electrical resistivity mapping was conducted to delineate boundaries and architecture of the Eumsung Basin Cretaceous. Basin boundaries are effectively clarified in electrical dipole-dipole resistivity sections as ...
-
(2003)Earthquake forecasting is one of the geophysical issues with a potentially large social and political impact. Besides the purely scientific interest, the loss of lives and the huge damage caused by seismic events in many ...
-
(2001)We present some recent progress in interpreting the results from the two powerful methods that analyze the magnetic pulsations observed by ground magnetometer arrays. The first method involves an inversion technique that ...
-
(2003)We report data from a series of dynamic crystallization experiments that focus on determining the partition coefficients (D’s) for V and Ti in the spinel + liquid system of an average type B1 CAI bulk composition for three ...
-
(2004)A distinctive feature of Ukrainian deep-violet diamond microcrystals is a broad absorption band centered at about 560 nm (17850cm(-1) or 2.21 eV). In the Ukrainian samples, the intensity of this band is almost two orders ...
-
(2003)The use of particle tracking methods to predict transport in single continuum and dual continua (mobile-immobile systems and fractured media) is studied. The accuracy of the particle tracking methods with different ...
-
(2002)Extant opinion about kriging is that all weights should be positive. Visualizations rendered by converting kriged grids to digital images are presented to show that negative weights may be beneficial to some spatial problems. ...
-
(2001)We describe the fundamental differences between weak (wave) turbulence in incompressible and weakly compressible MHD at the level of three-wave interactions. The main difference is in the structure of the resonant manifolds ...
-
(1989)The paper discusses data that support the view that the Sea of Okhotsk region is a dynamic geosynclinal region. However, at least in the southern part of the region, the geosynclinal process involved only the emplacement ...
-
(2004)The paper deals with the problem of electromagnetic pulses, which are generated in the earthquake centre at the very moment of main shock, and the co-seismic magnetic oscillations accompanying the propagation of the Love ...
-
(1989)The author investigates vertical motions of the lithosphere (L) resulting from a complicated injection of melt from the underlying asthenosphere. The kinematics of the process is illustrated. The complete system of equations ...
-
(2004)The possibility of flow of the lower crust under the load produced by carbonate sedimentary accumulations is investigated through the example of the Paris basin during the Middle Jurassic (i.e. Bathonian). Depositional ...
-
(2002)The theory of the proton magnetic resonance sounding (a.k.a. surface nuclear magnetic resonance) was first developed in free space. In this case, the alternative excitation field has no phase variation. Hence there is no ...
-
(2004)Existing models for seismic wave velocity dispersion and attenuation in porous rocks containing a mixture of two pore fluids are based on the assumption of a regular distribution of the fluid phases. However, in reality ...
-
(2001)This paper investigates the ability to retrieve the true soil moisture and temperature profiles by assimilating near-surface soil moisture and surface temperature data into a soil moisture and heat transfer model. The ...
-
(2000)Cetyltrimethylammonium-and tetradecyltrimethylammonium-intercalated magadiites were prepared by direct syntheses, starting from sodium metasilieate (NaaO/SiO2 = 1.0) and nitric acid. Total substitution of sodium by ...
-
(2002)During the last three billion years, the Earth has been experiencing a slow global cooling, expressed in the progressively increasing frequency and scale of glacial events. Based on these indications, geologic history can ...
