-
(1989)There are two different models that can be used to estimate the second-order seismoelectric effect. The Frenkel model describes the propagation of elastic waves in a disperse macroscopically homogeneous medium. The ...
-
(1999)In some previous work titration and Ni/Zn sorption edge/isotherm measurements carried out under a wide variety of experimental conditions on purified Na-montmorillonite were modelled in terms of cation exchange and surface ...
-
(2004)In this paper, we present a numerical model for simulating two-phase (oil-water and air-water) incompressible and immiscible flow in porous media. The mathematical model which is based on a fractional flow formulation is ...
-
(2003)A two-dimensional cross-section of a karst aquifer, in which chemical dissolution enlarges fractures with time, is studied. The karst aquifer is recharged by precipitation and drains towards a resurgence. The initial aquifer ...
-
(2002)Noble gases provide unique clues to the structure of the Earth and the degassing of volatiles into the atmosphere. Since the noble gases are highly depleted in the Earth, their isotopic compositions are prone to substantial ...
-
(1996)A model is presented that describes diffusive isotopic redistribution in layered fluid-rock systems where the solid and fluid interact by solution-precipitation. The models lead to guidelines for sampling in metamorphic ...
-
(2003)Amongst existing palaeogeographic models of the Rodinia supercontinent, or portions thereof, arguments have focused upon geological relations or palaeomagnetic results, but rarely both. A new model of Rodinia is proposed, ...
-
(2001)Resolution of the pattern of large-scale shear velocity variations above and below the known and postulated mantle discontinuities could provide con- straints on the nature of mineral phase transitions, changes in composition, ...
-
(2003)Computer simulations were used to clarify some principal problems of the interaction of natural waters of various types with natural and anthropogenic U-bearing phases U(cr), UO2(cr), U 4O9(cr), U3O8(cr), UO 2(OH)2(cr), ...
-
(2004)Modern analog analysis, the comparison of Quaternary fossil pollen assemblages with modern assemblages, has long been a mainstay of paleoecological and paleoclimatic inference. The logic of analogical inference involves a ...
-
(2003)Based on analysis of paleoclimate data for the Pleistocene (and the Phanerozoic as a whole), this paper advances a new concept of the orbital (astronomical) theory of paleoclimate. The need for a new concept is shown to ...
-
(2001)Monotremes developed a middle ear containing three auditory ossicles and a modified mandibular depressor independently of therian mammals. This suggests that the similarity between the most primitive therians and the Lower ...
-
(2003)We report results from a GPS network installed following special criteria in the framework of an international project and implications for recent crustal movements in the western Altai-Sayan region. The network includes ...
-
(2001)We sampled and analyzed surface sediments from 31 lakes along a latitudinal transect crossing the coniferous treeline on the Kola Peninsula, Russia. The major vegetation zones along the transect were tundra, birch-forest ...
-
(2003)The oxygen isotope composition of bone and tooth phosphate of 34 mice specimens (Pitymus sp., Microtus arvalis and Arvicola terrestris) coming from seven different locations in Italy, Germany and Switzerland was measured ...
-
(2000)Clay-mineral, heavy-mineral, and elemental distributions in sediments from the Arctic Ocean and the adjacent Laptev and Kara seas can be attributed to the geology of the hinterland and the transport of terrigenous material ...
-
(1998)The Urals structure, as a whole, is the result of the post-Permian sublatitudinal extension of the region. It is characterized by alternating submeridional zones: synform zones made up of nonmetamorphosed volcanogenic and ...
-
(2003)With the help of a 2D theoretical model, this paper analyses the modes of matrix detachment around a circular-elliptical rigid inclusion under pure and simple shear bulk deformations. Three modes of matrix detachment are ...
-
(2003)The study of condensates of high-temperature volcanic gases from different volcanoes showed the presence of up to 10 g/t Au [1]; however, the findings of mineral forms of gold are very scarce. Native gold was observed as ...
-
(1997)Amino acids were subjected to shock impact over a pressure range of 3.5 to 32 GPa both within and without meteoritic mineral matrices. The extent of amino acid destruction, racemization, and conversion to secondary amino ...
