-
(2002)In oxidizing environments, the toxic and radioactive element uranium (U) is most soluble and mobile in the hexavalent oxidation state. Sorption of U(VI) on Fe-oxides minerals (such as hematite [α-Fe2O3] and goethite ...
-
(2002)Indentation in the upper brittle crust where one plate is stiffer than the other produces vertical extrusion of a doubly vergent orogenic wedge. Sandbox models of this process show that erosion with or without deposition ...
-
(2002)Many experimental data demonstrate distinct differences between crystal-liquid partition coefficients Di measured under high temperature, anhydrous conditions and those determined at lower temperatures in the presence of ...
-
(2002)The carbon and nitrogen isotope composition of organic matter has been widely used to trace biogeochemical processes in marine and lacustrine environments. In order to reconstruct past environmental changes from sedimentary ...
-
(2002)We introduce a novel application of the Markov Chain Monte Carlo (MCMC) method to address the problem of characterising uncertainties in modelled thermal histories. As real data are never perfect, uncertainties in measurement ...
-
(2002)Copper transport and deposition in highly saline hydrothermal fluids are controlled by the stability of copper(I) complexes with ligands such as chloride and hydrosulphide. However, our understanding of the behavior of ...
-
(2002)Cenozoic pelagic ('red') clays of predominantly eolian and hydrogenous origin blanket much of the central North Pacific ocean basin. The eolian component is a key indicator of past paleoclimatic conditions; thus, Cenozoic ...
-
(2002)Sedimentation of biogenic and abiogenic components was studied in cores NGC108 (36°36.85'N, 158°20.90'E; water depth 3390 m) and S2612 (32°19.84'N, 157°51.00'E; water depth of 2612 m) from the Shatsky Rise to understand ...
-
(2002)We use a strain-rate-dependent visco-plastic rheology in a finite element model to investigate the effects of crustal rheology and thermal structure on the development of normal faults in 2-D extending lithosphere. Strain-rate ...
-
(2002)Two decades after their birth, the validity of fault slip inversion methods is still strongly debated. These methods are based upon a very simplified mechanical background, the Wallace-Bott hypothesis. Following previous ...
-
(2002)Anisotropy is frequently present in geological structures, but usually neglected when source parameters are determined through waveform inversion. Due to the coupling of propagation and source effects in the seismic ...
-
(2002)Although the flux of molecular O2 between the atmosphere and the subsurface is intrinsically linked to the net soil production of greenhouse gasses, few studies have focused on the controls affecting the isotopic composition ...
-
(2002)This study shows that the use of uniaxial recordings maintains the linear dependence of the low frequency displacements, with first polarities included, on the moment tensor components, and thus can be easily incorporated ...
-
(2002)A numerical modelling approach that simulates cracking and failure in rock and the associated seismicity is presented and a technique is described for quantifying the seismic source mechanisms of the modelled events. The ...
-
(2002)A new technique of temperature scaling method combined with the conventional Gibbs Ensemble Monte Carlo simulation was used to study liquid-vapor phase equilibria of the methane-ethane (CH4-C2H6) system. With this efficient ...
-
(2002)We report on the use of a pulsed gradient spin-echo imaging sequence for the three-dimensional (3D) imaging of water transport properties in two porous media: 2mm glass-beads and 0.15mm quartz-sand mixed with 2mm glass-beads. ...
-
(2002)A combination of advances in experimental techniques and mathematical analysis has made it possible to characterize phase distribution and pore geometry in porous media using non-destructive X-ray computed tomography (CT). ...
-
(2002)Deep seismic reflection profiles collected across Proterozoic-Archean margins are now sufficiently numerous to formulate a consistent hypothesis of how continental nuclei grow laterally to form cratonic shields. This picture ...
-
(2002)Water flux was investigated in the frame of the project 'preferential flow paths-3D water and solute dynamic in heterogeneous media'. The objective of the study was the non-destructive three-dimensional monitoring and ...
-
(2002)Agreement about planetary formation processes deteriorates sharply with distance from the Sun. While the terrestrial planets are widely believed to have formed from the collisional accumulation of solid bodies, there are ...
