| 摘 要： | 以我国某海域为例，探讨了航空重、磁相关性分析方法及其应用。通过计算航空重、磁相关系数，结合研究区地质特征，将航空重、磁异常划分为三类：即同源异常、半同源异常和非同源异常，分别描述了这三类异常的重、磁特征，推断了异常源性质及地质特征，不仅减少了研究区地质解释的多解性，而且使解释成果更加符合客观实际。

| Abstract: | Exemplified by the exploration in a certain sea area in China,the authors discussed the correlation analytical method and its application to airborne gravity and magnetic anomalies.Through computation of the correlation coefficient of airborne gravity and magnetic anomalies in combination with geological characteristics,the authors divided airborne gravity and magnetic anomalies into three types,namely homologous,half homologous and non-homologous anomalies,described these three kinds of anomalies and inferred the features of the source and geological characteristics.The results can not only reduce the multi-solution of geological interpretation but also make the interpretation more in accord with the reality. |
