Abstract：

Linear and circular interpretation structure maps of different relative depths are obtained by processing 1: 200000 aeromagnetic data to the pole in Ailaoshan region, interpreting upward extension of 4 heights, extracting a vertical second derivative line of 0 value and a series of calculations. Concealed boundary of deep magnetic rocks can be delineated according to the maps. On the basis of the conclusions above, a set of economical and practical methods to graph the deep structure are summarized. In addition, the relationship between deep structure and mineralization positions is discussed.
