Abstract:Based on the high density electrical inversion results, we investigate and study the trace distribution and structural features of Sumatou fault combing with drilling, exploration well and other engineering survey methods. We observe the terrain of Sumatou fault, and conduct 14C dating of stream terraces. The dating result is 13 436±210~40 724±6 332 a, indicating that the Sumatou fault has not been active since the late Pleistocene. It is concluded that the Sumatou fault is an NNE trending buried fault with a strike of about 25°, a tendency of SE, a dip angle of about 65°, and a fractured zone width of about 20 m. The latest active age of Sumatou fault is the middle Pleistocene.
