对解释重磁异常的某些“经验法则”,我们都比较熟悉.在25年以前出版的几本著名的教科书中都能找到很多这方面的例子.从这些例子中可以看到,如何量出“半宽度”、“斜率-长度”等参数,来估算异常源的埋深.当我们见到一张新的异常平面图或异常剖面图时,经常是用这种经验方法先作一粗略的估算. 另外,还有些大家熟悉的文献,向我们介绍了如何在异常剖面图上量取更关键的某些特征参数,并把它们绘成列线图,用来更精确地求得异 We are familiar with some of the “rules of thumb” that explain gravity and magnetic anomalies, and many of these examples are found in several notable textbooks published more than 25 years ago. From these examples, one can see how to measure Half-width, “” slope-length, "and other parameters to estimate the depth of anomalous sources.When we see a new anomaly plan or anomalous profiles, it is often the first to make a rough estimate using this empirical method In addition, there are some well-known literatures that show us how to take more critical characteristic parameters on an abnormal profile and plot them as nomograms to find the difference more accurately
