大陆的裂谷作用常发生于古老的逆冲带内,例如,在美国西部,地壳由于前渐新世的逆冲作用而增厚的地区与遭受从渐新世到全新世扩张作用的地区之间有极大的相关性。大洋盆地演化的威尔逊旋回是以洋盆常沿古逆冲带形成的观察为依据而提出的。虽然人们已将古逆冲带中的裂谷作用归因于先前构造的再活化,但是在某些地区,无论是高角度的还是低角度的拉伸断层都明显地横切逆冲断层,而不是使它们活化。这表明,先前断层的再活化或许并非是裂谷带常沿逆冲带发生的唯一理由。 Vink等人(1984)认为:由于大陆岩石圈历来比海洋岩石圈软,故裂谷易发生在陆壳上。在地壳底部和上地幔预示的温度以及板块构造应变速率条件下,石英的流动应力要比橄榄石 The rifting in the continent often occurs in ancient thrust belts. For example, in the western United States, the crust thickens due to the thrust of the Oligocene and the area exposed to the expansion from Oligocene to Holocene Between the great relevance. The Wilson cycle of the oceanic basin evolution was based on the observation that the ocean basin was formed along the paleostoid zone. Although the role of rifting in paleostuds has been attributed to the reactivation of previous structures, in some areas, both high-angle and low-angle tensile faults clearly transverse the thrust fault, whereas Not to activate them. This suggests that the reactivation of previous faults may not be the only reason that the rift zone often occurs along the thrust zone. Vink et al. (1984) argue that since the continental lithosphere has always been softer than the oceanic lithosphere, the rift easily occurs on the continental crust. Under the predicted temperature of the bottom and upper mantle of the crust and the tectonic strain rate of the tectonics, the flow stress of quartz is higher than that of olivine
