摘　　要：通过分析倾斜角概念,提出利用反双曲正切函数特性对归一化的垂向导数进行变换处理,来识别重磁异常中地质体边界和提取地质体分布、断裂构造平面展布特征等信息。理论模型和实际资料对比分析表明,利用该方法识别重磁异常边界具有较好的效果和较高的分辨能力,能够获取丰富的地质信息,对识别地质体边界、划分大地构造单元、确定断裂带和地质构造走向等具有一定的意义。Through the analysis of tilt angle concept, this paper puts forward a method for normalized vertical derivative using the char- acteristies of Inverse Hyperbolic Tangent function, with the purpose of detecting geological boundaries in potential field and extracting geological body distribution, characteristics of fracture structure and other geological information. Theoretical models and practical data processing show that the method can be an effective method for detecting geological boundaries with higher resolution and obtaining a- bundant geological information and is also of certain significance for detecting the geological boundaries, dividing tectonic units, and determining the fracture zone and the trend of geologic structure.
