| Summary: | abnormally high pore pressures. The purpose of this study accretionary prisms and continental thrust belts. However, are to be expected in tectonic wedges which have the physical body of water increases total pore pressure throughout the can be generated within a thrust belt by conditions which are concentration of excess pore pressure and X beneath the toe creatina conditions favorable for rock failure and new thrust difference technique was used to investigate the sensitivity Erosion slightly increases excess pore pressure beneath the even low permeability rocks may not be effective in impeding faults forming in that area. The presence of an overlying foreland fold and thrust belt. A two-dimensional finite formation. Permeability changes have the greatest influence given to the effect of erosion on the evolution of pore little is known about the origin and evolution of any massive fluid dissipation in the face of slow thrust motion. of excess pore pressure generation and dissipation to the of the thrust sheet, thus decreasing the probability of new often highest directly beneath the toe of the thrust sheet, over pore pressure evolution within a thrust belt especially permeability, and thrust velocity). Special attention was pore pressure. pressure within a submerged thrust belt exhibiting pressures and X (the Hubbert and Rubey parameter) are most pressures in continental thrust belts. Workers have also properties and boundary conditions appropriate for both results of this model predict that high excess pore pressures shown through modeling studies that abnormal pore pressures stratigraphy typical of North American thrust belts. The There is indirect for the existence of abnormal pore thought to exist in continental thrust sheets. Excess pore thrust sheet, but it does not significantly increase excess toe of the thrust, however, it also broadens the variation of physical properties of a thrust sheet (e. was to compute the pore pressures in the frontal part of the when vertical pemeabilities are less than 10-17 M2.
