有人认为,在许多情况下,大陆地壳的平均强度是十分低的(几十 MPa),因此,地壳对岩石圈的大规模变形影响甚小,但是,实验室的摩擦研究结果与简单断裂理论相结合(以及由地壳3公里以上的原地应力测量值外推)则意味着,如果在中地壳深度孔隙压力大致为静水压力,那么地壳强度是可以估算的(几百 MPa),并且可能明显地制约岩石圈变形 Some people think that in many cases, the crust average intensity is very low (tens of MPa), so the crust has little effect on the large-scale deformation of the lithosphere. However, the results of the laboratory friction study are similar to those of simple fracture theory Combining (and extrapolating from in situ stress measurements up to 3 km above the crust) means that crustal strength can be estimated (hundreds of MPa) if the pore pressure at the mid-crust depth is approximately hydrostatic, and it may be obvious Restricting lithospheric deformation
