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.
