(1989)Three long-lasting epochs in the earth's tectonic evolution are identified. First, the Catarchean epoch was characterized by the earth's endogenic passivity. Then, the exceptionally active Archean epoch was dominated by ...
-
(1997)Melt inclusions were studied in olivine, plagioclase, and orthopyroxene from nine basaltic andésite samples collected on young cones of the Medvezh'ya caldera on Iturup Island, southern Kuril Archipelago. Melts of the ...
-
(1997)The classical model of faulting predicts that slip planes occur in two conjugate sets. Theoretically, more sets can be contemporarily active if pre-existing structures are reactivated in a three-dimensional strain field. ...
-
(2002)A 3-D finite-element scheme for direct current resistivity modelling is presented. The singularity is removed by formulating the problem in terms of the secondary potential, which improves the accuracy considerably. The ...
-
(2004)A new approach for predicting traveltimes is proposed which makes use of sophisticated smoothing and interpolation techniques applied to observations from large earthquake catalogues. The technique produces 3-D empirical ...
-
(2004)Numerical studies of ductile deformations induced by salt movements have, until now, been restricted to two-dimensional (2D) modelling of diapirism. This paper suggests a numerical approach to model the evolution of ...
-
(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 3-D frequency-domain solution based on a volume integral equation approach has been implemented to simulate induction log responses. In our treatment of the problem, we assume that the electrical properties of the bedding ...
-
(2002)A 3-D finite-difference solution is implemented for simulating induction log responses in the quasi-static limit that include the wellbore and bedding that exhibits transverse anisotropy. The finite-difference code uses a ...
-
(2002)Three-dimensional (3-D) electromagnetic (EM) inversion is increasingly important for the correct interpretation of EM data sets in complex environments. To this end, several approximate solutions have been developed that ...
-
(2002)Continental rifting is treated as a mechanical instability developing under horizontal tectonic tension. The instability results in strain localization and the formation of a neck, which is interpreted as a rift zone. At ...
-
(2002)A three-dimensional (3D) mass transport numerical model is presented. The code is based on a particle tracking technique: the random-walk method, which is based on the analogy between the advection-dispersion equation and ...
-
(2001)We describe a novel technical approach to accurately measure surface area and other morphological characteristics of corals and similar irregular objects from underwater photography. A standard Nikonos camera system was ...
-
(2004)A Lagrangian perturbation method is applied to develop a method of moments for reactive solute flux through a three-dimensional, nonstationary flow field. The flow nonstationarity may stem from medium nonstationarity, ...
-
(2003)Orthopyroxene porphyroclasts in peridotite mylonites are elongated to variable extents depending on the crystallographic orientation. This paper presents a 3D numerical model of the development of lattice- and shape-preferred ...
-
(2002)We develop an algorithm to model the magnetometric resistivity (MMR) response over an arbitrary 3-D conductivity structure and a method for inverting surface MMR data to recover a 3-D distribution of conductivity contrast. ...
-
THREE-DIMENSIONAL NUMERICAL SIMULATIONS OF CRUSTAL DEFORMATION AND SUBCONTINENTAL MANTLE CONVECTION (1997)3-D simulations of mantle convection allowing for continental crust are explored to study the effects of crustal thickening on lithosphere stability and of continents on large-scale mantle flow. Simulations begin with a ...
-
(1999)Application of the Inverse Teleseismic Scheme for data of the International Seismological Center permitted derivation of the 3D structure of seismic heterogeneities at the depth interval between 100 and 700 km beneath the ...
-
(2004)We calculate three dimensional (3-D) sensitivity kernels for fundamental-mode surface wave observables based on the single-scattering (Born) approximation. The sensitivity kernels for measured phases, amplitudes and arrival ...
