Lithostatic load
Web25 jan. 2024 · Previous surveys of in situ pore pressure in this region reveal overpressures reaching >85% of lithostatic load within a zone of confined fluid flow at the frontal thrust near the deformation front. Our results indicate that elevated pore pressures persist well beyond the frontal thrust in the central CSZ. WebThe stress that results from the weight of overlying materials (overburden). Also called overburden stress and lithostatic pressure. Rock failure prevents formation pressure …

Web27 apr. 2024 · —The increase in lithostatic pressure was induced by an intrusive body (magmatic load). In this case, a significant increase in temperature must have been provided by heat from magma crystallization (the typical latent crystallization heat values are orders of magnitude higher than those of heat generated by radioactive sources) [ 44 ], …
WebNormal faults growing in the Earth's crust are subject to the effects of an increasing frictional resistance to slip caused by the increasing lithostatic load with depth. We use three-dimensional (3-D) boundary element method numerical models to evaluate these effects on planar normal faults with variable elliptical tip line shapes in an elastic solid.
