Abstract: By use of fault slip data in invesion of using different-stage tectonic stress tensors,we have obtained two stages of tectonic Quaternary stress field of the Xianshuihe fault zone. In the first stage(from early-mid Pleistocene),the tectonic stress field is characteristic of NE-SW compression. In the second phase(from late-Pleistocene to the present),the tectonic stress field is mainly characteristic of nearly E-W compression and nearly S-N extension. In this stress field,the Xi-anshuihe fault mainly shows a left-lateral slip.
