摘要
本文介绍了一种用水平梯度极大值确定密度和磁性体边界的方法，并由计算机自动搜索成图。可广泛用于区域重磁异常的构造解释之中。
A method for locating the boundaries of magnetic or gravity sources is prcsented in this paper. This method is of based on the principle that the maximum horixontal gradi- ent a gravity anomaly or a pseudo-gravity anomaly, which is transformed from magnet- ic anomalies located very nearly on the edge of tabular sources. An automatic scan ninig scheme is used to find the coordinated of the maximums.The tests for the synthet- ic data and field data show that this method is of efficiency and convenience for the tec- tonic interpretation of magnetic and gravity anomalies.
