-
(2002)Asymmetric boudinage structures are commonly used as shear sense indicators but their development is incompletely understood. This paper describes the influence of initial shape and kinematic parameters on the evolution ...
-
(2003)A three-dimensional numerical model of sediment transport and deposition in coarse-grained deltas is used to investigate the controls on depositional sequence variability in marine half-graben extensional basins subject ...
-
(2003)A numerical code has been used to simulate the flow patterns in geological soft sediments that are driven by buoyancy forces resulting from reverse-density stratification. The aim was to provide a clearer understanding of ...
-
(2000)The strain within lava tubes is described in terms of pipe flow. Strain is partitioned into three components: (a) two simple shear components acting from top to bottom and from side to side of a rectangular tube in transverse ...
-
(2001)Dipping reflectors in the upper mantle are observed on reflection seismic data and, in some cases, have been interpreted to represent mantle shear zones. It is not clear, however, how these shear zones develop and under ...
-
(2004)The Dniepr–Donets Basin (DDB) is a Late Devonian rift structure located within the East-European Craton. Numerical heat flow models for 13 wells calibrated with new maturity data were used to evaluate temporal and lateral ...
-
(2003)Predictions from dynamic modelling of the lithospheric deformation are presented for Northern Europe, where several basins underwent inversion during the Late Cretaceous and Early Cenozoic and contemporary uplift and erosion ...
-
(2002)A 2-D numerical model is used to investigate the evolution of accretionary wedges and fold-and-thrust belts. The numerical method is based on the distinct-element method (DEM). Unlike many continuum numerical models, DEM ...
-
(2001)The formation of a continuous crystal network in magmas and lavas can provide finite yield strength, τy, and can thus cause a change from Newtonian to Bingham rheology. The rheology of crystal-melt suspensions affects ...
-
(2003)Statistical evaluation of the results of palaeostress analysis is hindered by the fact that the common fault-slip methods provide incomplete information about the stress tensor. Our favoured approach to solving this problem ...
-
(2005)Volcanic eruptions are unsteady multiphase phenomena, which encompass many inter-related processes across the whole range of scales from molecular and microscopic to macroscopic, synoptic and global. We provide an overview ...
-
(2002)First-order elastic wave scattering theory, validated in general features by deep-borehole seismic coda wave observations, is used to numerically simulate time-lapse borehole seismic data aimed at monitoring oil-water ...
-
(2002)Seismic images and sediment core data from the Bear Island and Isfjorden fans localized along the Svalbard–Barents Sea continental margin, reveal an interesting depositional system consisting of stacked debris flow lobes. ...
-
(2001)Phase equilibria at temperatures up to 800degreesC and pressures up to 12 kbar were numerically simulated in the SiO2-LiAlSiO4-H2O singular system that includes quartz, petalite, alpha-spodumene, beta-spodumene, and ...
-
(2002)An objective common to many watershed studies is to separate storm hydrographs into two components: water that was present in the watershed prior to a storm event (soil moisture and groundwater) and water which fell on the ...
-
(2003)We model seismic wave propagation in media with discrete distributions of fractures using the pseudospectral method. The implementation of fractures with a vanishing width in the 2-D finite-difference grids is done using ...
-
(2002)Numerical 3D simulations of the development of spiral inclusion trails in porphyroblasts were conducted in order to test the proposals that (a) 3D spiral geometry differs between the rotation and nonrotation end-member ...
-
(2004)In this paper, firstly the mesoscopic elemental mechanical model for elastic damage is developed and implemented into the rock and tool interaction code (R-T2D). Then the failure processes of a heterogeneous rock specimen ...
-
(2001)In this paper, the numerical stability and efficiency of methods of harmonic downward continuation from flying altitudes are treated for sampled gravity field data. The problem is first formulated in its continuous form, ...
-
(1999)In current views on the origin of deep-focus earthquakes the presence of metastable olivine in subducting slabs plays a central role. In this study we construct synthetic slab models to investigate the expression of ...
