摘要
通过研究辽宁省布格重力异常Δg及其位场转换场、航磁ΔT异常及其位场转换场、地震波场、大地电磁场,结合地貌以及钻探等资料,综合解释出了区内断裂构造.展示出了辽宁省断裂构造平面分布特征.配合地球物理解释剖面,可以了解区内主要断裂构造的垂向发育特征.分析认为郯庐断裂带为左行走滑断层带,划分出了表壳断裂、中-下地壳断裂、超岩石圈断裂.
With study on the Bouguer gravity anomaly Zig and its potential field conversion field, aeromagnetic anomaly ATand its potential field conversion, seismic wave field and magnetotelluric field, combined with the topography and drillingdata of Liaoning Province, the author comprehensively interprets the fault structures, which show the plane distributioncharacteristics of faults in the province. Together with the geophysical interpretation section, the vertical developmentcharacteristics of main fault structures can be recognized. The analysis reveals that the Tan-Lu fault zone is of left lateralstrike slip. The faults can be divided into supracrustal fault, middle-lower crust fault and translithospheric fault.
