摘　　要：哀牢山地区是中国重要的金、多金属成矿带,构造成为该区最重要的控矿因素之一。在利用1:20万航磁数据解译该区深部构造时,考虑到该区地壳厚度,对航磁分别进行上延40km、20km、10km、5km位场处理。同时结合现有地质资料及该区重要矿种金、铜、铅锌、锡的矿床分布特点,探讨了矿床与深部解译构造的关系,得出哀牢山地区航磁解译构造中的几种有利成矿部位,总结归纳了一套利用航磁解译构造圈定找矿远景区的方法,圈定了哀牢山地区10个潜在的找矿远景区,进一步探讨了新的找矿方向。Ailao Mountain area is an important gold-polymetallic ore-forming belt in China, and structure is one of the most important ore-controlling factors in this area. Considering the crustal thickness, the authors processed potential fields with upward continuations of 40 km, 20 km, 10 km and 5 km when using the 1：200000 aeromagnetic data to interpret the deep structure in this area. Meanwhile, the relationship between the ore deposits and the interpretation of structure was studied in combination with the available geological data and the distribution features of such elements in the main deposits as Au, Cu, Pb, Zn and Sn. Several favorable ore- forming places are detected, a set of methods for delineating prospective areas are summarized and ten promising potential areas are delineated. In addition, the new orientation for ore prospecting are tentatively discussed.
