At the present stage, the integrated anomaly map is prepared on the basis of single element anomaly map, only the integrated anomaly range can be delineated qualitatively, the superposition contribution of outliers cannot be considered, and the synthetic anomaly cannot be evaluated quantitatively. It is found that there are many shortcomings in this kind of maps both in the form of surface representation and the application effect. In this paper, the authors defined the concept of "average contrast method" and put forward the idea and method of using "average contrast method" to compile integrated anomaly map. Based on the original analysis data, the authors used the average contrast degree to quantitatively express the integrated anomaly range, thus forming an integrated anomaly map of average contrast. The contrast result shows that the average contrast method is better than the additive contrast method and the integrated contrast method. The average anomaly integrated anomaly map is particularly suitable for 1:50000 geochemical exploration census data development research on account of small range and concentration center. It is suitable for accurate layout of the surface prospecting project and can save the cost of exploration as well as improve ore hit rate.
