Abstract: Based on the previous research and our latest chemical exploration,the more exact location of the Pinggan fault has been determined.By the comparison with the test values,we found that the fault along the southwestern section is bigger than that along the northeastrn part.A trial investigation on the recent activity of the fault has been made as well.
