The paper is devoted to the modeling of processes of inelastic nonhydrostatic compaction and decompaction of low porosity geomaterials such that each pore can be considered as an isolated cavity in a solid matrix. A real material containing a large n

A combination of thin- and thick-plate theories, and finite element models is used to systematically analyze folding in multilayer stacks. We show that if the interlayer spacing is large, individual layers fold as single layers, if the spacing is sma

The lithosphere is subject to fluctuations in temperature and pressure during the formation of sedimentary basins. These fluctuations cause metamorphic reactions that change the density of the lithosphere, which, in turn, influences basin subsidence.

The near-surface compaction regime of most sedimentary basins is characterized by hydrostatic fluid pressures and is therefore determined entirely by sediment matrix rheology. Within this regime, compaction is initially well described by a pseudoelas

We analyzed and compared the mixing properties of 2-D mantle convection models. Two rheologically different models, Newtonian and non-Newtonian (power-law), were considered with both the line and field methods. The line method is based on monitoring

Compaction driven fluid flow is inherently unstable such that an obstruction to upward fluid flow (i.e. a shock) may induce fluid-filled waves of porosity, propagated by dilational deformation due to an effective pressure gradient within the wave. Vi

An integrated approach combining the available geological-geophysical information was employed to construct a series of paleogeographic maps of the northwestern part of the Dnieper Donets Basin (DDB) during the Late Visean-Serpukhovian (Early Carboni

We have studied the initiation of salt diapirs with frictional overburdens under lateral compression and extension. The overburden is assumed to be elasto-plastic with Mohr-Coulomb yield criterion and non-associated flow rule. Plastic flow localizes

Numerically modelled diapirs that rise into overburdens with viscous rheology produce a large variety of shapes. This work uses the finite-element method to study the development of diapirs that rise towards a surface on which a diapir-induced topogr

Many data show that large masses of silicic magma can be formed by crustal anatexis under the influence of volatiles, possibly enriched in primary water derived from a mantle source. In the present paper, a model of crustal anatexis, accompanied by a
