为利用区域物化探资料预测找矿靶区，分析了土屋、延东铜矿床成矿地质背景及区域重、航磁、化探异常特征。土屋和延东铜矿床均为斑岩型铜矿床，母岩为花岗斑岩和闪长斑岩。它们位于大草滩断裂和康古尔断裂之间，在高磁异常区南侧，在康古尔重力异常梯度带内，处于高铜背景和铜化探异常区。通过对重磁资料的处理，提取出线形和环状构造。认为土屋、延东铜矿田处于东西走向的线与南北、西北、东北方向的隐伏线和环形构造的交汇处。最后给出了矿田预测模型和找矿指标。
In order to predict exploration target using the regional geophysical and geochemical data, this paper analyzed the ore-forming geological background and the characteristics of regional gravity, aeromagnetic and geochemical anomaly of Tuwu and Yandong copper deposits. Tuwu and Yandong copper deposits are porphyry deposits which their mother rock are granite porphyry and diorite porphyry. They are located between the Dacaotan fault and kanggu-er fault, at southern side of high magnetic anomaly region, in Kanggu-er gradient zone of gravity anomaly, and in high copper background and copper geochemical anomaly region. By dealing with gravity and aeromagnetic data, the lineament and circular structures were extracted. We can conclude Tuwu and Yandong copper deposit field was located at the crossing of lineament that trend eastwest, hidden lineament that trend north-south , northwest and northeast and circular structures. Finally, predicting model of orefield and indicators of prospecting was given.
