在电子计算机技术应用于物探资料处理以前,垂向二次导数的计算主要用于消除重力资料中的区域场以突出局部场和分解多体场源的迭加异常。随着频谱分析方法和电子计算机技术在物探资料解释中的逐步推广使用,垂向二次导数异常的计算成了磁异常数据处理和解释主要内容之一。垂向二次导数异常为磁异常的推断解释提供某些与地质体形态更为直接相关的信息,而大量的磁异常资料又为垂向二次导数方法的应用提供广阔的前景。从而,垂向二次导数方法又重新引起人们的兴趣和重视,近年来,国内就发表了不少关于垂向二次导数物
Before the application of computer technology to geophysical data processing, the calculation of vertical second derivative was mainly used to eliminate the regional field in gravity data to highlight the local field and to decompose the superimposed anomaly of multi-body source. With the wide application of spectrum analysis and computer technology in the interpretation of geophysical data, the calculation of vertical derivative anomaly has become one of the main contents of magnetic anomaly data processing and interpretation. Inferred explanations for magnetic anomalies with vertical second derivative anomalies provide some more direct information related to the morphology of the geological body, while a large number of magnetic anomalies provide broad perspectives for the application of the vertical second derivative method. Thus, the vertical derivative method again aroused people’s interest and attention, in recent years, many domestic published on the derivative of the second derivative
