According to the result of aeromagnetic anomalies upward continuation it is considered that the fault zone is a sinistral strike-slip fault and its biggest leap distance is about 53 km. According to Bouguer gravity anomalies upward continuation there is a shallower cutting depth with Hanling -Pianling fault zone. It mostly developed in the sedimentary cover. The processing and interpretation results of four integrated geophysical profiles show that the occurrences of Hanling -Pianling fault are various in different locations the deep tendency of the western fault is N the apparent dip is about 65 while the deep fault in the middle tends to NW its apparent dip is about 60 the north of the deep fault tends to NW and SE and the change of apparent dip is large about 35 ~ 50 according to its swing feature.
