重磁异常数据处理中的数字增强方法

The digital enhancing interpretation method for gravity and magnetic data

针对重磁异常，建立一个异常光照模型，并通过该模型生成三维异常光照曲面图。由于异常光照模型强化了异常特征细节，使得类似于断裂、岩坝、岩墙、褶皱轴部等异常特征在三维曲面图中得以明确地表达。

For the gravity and magnetic anomalies a model of the anomaly in light is built.From the model a 3-D curved surface of anomaly in light is given. Because this procedure has the effect of enhancing features, the dikes, contants and so on that are notseen on the original anomaly maps, could be emphasized and judjed clearly on the 3-Dcurved surface.
