| Abstract: | Numerous published analyses of the nontectonic state of stress are based on Hooke‘s law and the boundary condition of zero horizontal deformation. This approach has been used to determine the gravitational stress state as well as the effects of processes such as erosion and temperature changes on the state of lithospheric stress. The major disadvantage of these analyses involves the assumption of lateral constraint which seems unrealistic in view of the observational fact that the crust can deform horizontally in response to applied loads. If the same problems are addressed by assuming that the remote stress state is constant, instead of the condition of zero horizontal deformation, then the resulting stress states are entirely different and in good accord with observations. The processes of erosion and sedimentation have slight tendencies to increase and decrease, respectively, the state of deviatoric stress. Temperature changes have only minor effects on the stress state, as averaged over the thickness of the lithosphere. -from Author |
