摘要：

Low-angle normal faults seem to violate the criterion that relates fault dip to stress orientation. To explain such faults one must postulate a 45°rotation of principal stress directions at mid-crustal depths, which is difficult to understand on the basis of previous elastic crust models. Such a stress rotation is shown to be a natural consequence of a low-viscosity lower crust. © 1990 Nature Publishing Group.
