摘　　要：断裂构造是构造运动的一种重要表现形式,在地壳发展演化的各个不同阶段都有发生。断裂构造解释推断工作是重磁资料研究的主要工作内容。利用重磁场对断裂构造进行解释推断,特别是对区域性隐伏的构造的解释效果要优于其它方法。解释推断方法是以重磁场的相对变化为依据,以数据处理为手段。通常数据处理以场的转换、异常分离、定性、定量解释为主要内容。Fault structure is an important manifestation of tectonic movement,occurring at different stages of crustal development and evolution.The interpretation and inference of fault structures is the main task of gravity and magnetic data research.The use of gravity and magnetic fields for interpretation and inference of fault structures,especially for regional concealed structures,is more effective than other methods.The method of interpretation and inference is based on the relative changes in the gravitational and magnetic fields,using data processing as a means.Usually,data processing focuses on field transformation,anomaly separation,qualitative and quantitative interpretation.
