摘要
Sainan imbricated thrust system is a kind of typical nappe structure. Using the method of plot excess area, this paper calculates the detachment depth of this thrust system. The calculating result shows that the detachment depth is about 15 km underground and tbe shorteuiug of the strata is much more than 700 m. Analysis of fault growth indexs and seismic reflection profiles reveals that this thrust system is developed by the mixing propagation, from piggyback propagation to overstep propagation.
