Article Abstract:

Separation of the crust is a common occurrence when continents collide. It happens when the subsiding plate of a continent reachesthe subduction zone faster than the adjacent areas. The South China block need not have a rectangular promontory on the northern margin for nonsynchronous collision. This promontory is also not needed to explain why the Tanlu fault stops at its southern end. This means that if the original northern edge of the South China block was smooth, then at least 400 kms. of the South China block would have been consumed west of the Tanlu fault.

Article Abstract:

Zheng-Xiang Li suggests that the upper crust of the South China block was separated from the lower crust and thrown over into the North China block when the South and North China blocks collided. This phenomenon occurred east of the Tanlu fault. He also claims that the sinistral offset of the Qinling suture is only 110-120 kms. deep. However, Li does not elaborate on why the South China block separated east of the Tanlu fault and not to the west. Nor is there any explanation given for the sinistral offset of the Qinling suture.
