(1996)A numerical model is proposed for the mechanism of a rockslide avalanche on the slope of Koryakskiy volcano caused by the emplacement of sheeted intrusive bodies. The model of non-stationary geomechanical processes with ...

(Федеральное государственное бюджетное образовательное учреждение высшего образования «Донской государственный технический университет», 2017)The problem of numerical modeling of the process of initiation of seismic activity on Arctic shelf and its impact on engineering structures is considered. To describe the dynamic behavior of a geological array, the determining ...
-
(2003)In this paper we consider crystallization of solid solutions and formation of growth zoning in minerals. To ascertain the role of various mechanisms producing zoning we have constructed kinetic models of nonsteady solid ...
-
(2001)With the help of two-dimensional numerical models this paper investigates three aspects of heterogeneous deformation around rigid objects: (1) the nature of particle paths; (2) the development of strain shadow zones; and ...
-
(2001)A set of empirical equations is developed which allows calculation of chromian spinel composition in equilibrium with a basaltic melt under a known set of conditions. These equations are calibrated with published experimental ...

NUMERICAL MODELING OF NEOTECTONIC MOVEMENTS AND THE STATE OF STRESS IN THE NORTH CAUCASUS FOREDEEP (2002)This paper examines modern tectonic processes and the state of stress in the North Caucasus along three profiles that cross its eastern, central, and western parts. Using the models of crustal structure along these profiles, ...
-
(2001)Methodology of automatic tracking of trajectories of cracks has been offered. The methodology has been ground and is suitable for quantitative investigation of growth of cracks and deformation of rocks during compression. ...
-
(2002)Herein we present numerical simulations of Chicxulub-scale impact events. We used the three-dimensional version of the SOVA (solid, vapor, air) computer code in hydrodynamic approximation (no strength) to model the initial ...
-
(2006)Numerical modeling of generation and propagation of tsunami waves caused by underwater earthquakes in the Black Sea basin is carried out using the model of dynamic seismic source. A number of historical tsunamis are ...
-
(2000)Analyzed in this paper are the stationary and nonstationary models for the formation of the thermal state of the lithosphere in the axial zones of the mid-oceanic ridges. It is demonstrated that stationary models allow one ...
-
(1987)This paper describes a three-dimensional discrete model of the annual climatic circulation of a deep, thermal-stratified lake. The laws of conservation of heat and mass are exactly satisfied in it, and morphometry is taken ...
-
(2003)The thermomechanical processes associated with formation of large igneous provinces (LIPs) remain poorly understood owing to fundamental difficulties in simulating plume–lithosphere interactions in current numerical models. ...
-
(1988)The concept of long-lived magma chambers in which goechemical evolution is controlled by periodic replenishment, tapping (eruption), and crystal fractionation, the so-called RTF chamber, is the subject of previous numerical ...
-
(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 ...
