众所周知,确定断裂构造是区域重力资料解释中的一项重要内容.我们在研究辽宁西部地区三万余平方公里1∶20万重力资料过程中,初步归纳出确定该区断裂构造的八条标志,即:①线性梯度带;②异常的线性过渡带;③狭长异常带;④异常突然错动的界限;⑤等值线的规划性扭曲;⑥等值线的疏密突变带;⑦异常宽度突变处;⑧两侧异常特征明显不同的分界线. 下面结合实例就上述标志的重力异常特征和地质简况逐一说明.
As we all know, to determine the fault structure is an important part of the interpretation of the regional gravity data.We studied the study of 1: 200000 km2 in Western Liaoning 1: 200000 gravity data, initially identified to determine the fault structure of the eight signs, namely : ① linear gradient zone; ② abnormal linear transition zone; ③ slender anomalous zone; ④ abnormal sudden misalignment boundaries; ⑤ contours of the planned distortion; ⑥ contours of the density mutation zone; ; ⑧ distinct characteristics of both sides of the distinct boundaries of the following combination of examples of the above signs of the gravity anomaly characteristics and geological conditions one by one instructions.
