| 摘 要： | 通过对4条高精度重力、高精度磁测和MT实测非震地球物理综合剖面的处理解释,结合已有区域地球物理及野外地质研究,对辽宁东部寒岭—偏岭断裂带的特征进行了研究。根据航磁异常上延结果,认为该断裂为左旋走滑断裂,其最大错断距离约53 km。布格重力异常上延结果表明,与寒岭—偏岭断裂带相关的次级断裂切割深度小,主要发育在沉积盖层中。四条非震综合物探剖面处理解释结果表明,寒岭—偏岭断裂带在不同地段的深部地质产状不同,断裂带西段深部倾向为N,视倾角约为65°;断裂带中段深部倾向NW,视倾角约为60°;断裂带北段深部倾向NW或SE,具有摆动特征,视倾角变化较大,约为35°~50°。

| Abstract: | On the basis of the comprehensive interpretation of four high- precision gravity，high- precision mag- netic and MT measured non- seismic geophysical profiles，combining with the regional geological data and field geo- logical research，the authors studied the features for the deep Hanling- - Pianling fault zone in eastern Liaoning． Ac- cording 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 con- tinuation，there is a shallower cutting depth with Hanling- - Pianling fault zone． It mostly developed in the sedimenta- ry 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 appar- ent 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 fea- ture． |
