这种特征可能不仅和海洋与大陆板块汇聚边界的岛弧海沟上的基本应力状态有关,而且与自转速率不均匀产生的附加应力状态有关。
These correlations depend not only on the state of the basic stress field in the island arc-trench but also on the additional stress field caused by the variation of rotation velocity of the earth .

简单剪切发生在晚白垩世&早始新世,其动力与太平洋板块俯冲带的后撤、太平洋板块与欧亚板块之间汇聚速率的降低、以及先存北倾缝合带等密切相关。
The simple shear extension mainly occurred in Late Cretaceous-Early Paleogene , related to slab roll back of Pacific plate , decreasing Paleogene Pacific-Eurasia convergence rate and possible preexisting suture zone .
