土屋、延东铜矿田综合信息预测模型

为开发区域物探、化探资料进行找矿靶区优选，选择土屋、延东铜矿作为建模矿田．在分析成矿地质背景、区域重力航磁地球化学特征的基础上，利用重力、航磁数据处理资料提取了深部线性构造和环型构造，结合铜元素等地球化学异常分布，指出土屋、延东斑岩铜矿田位于EW向区域性线性构造、近NS向、NW向、NE向隐伏线性构造和环型构造的交汇部位和铜高背景及局部异常区中，提出了斑岩型铜矿田预测模型和“三位一体”的找矿标志．

THE PREDICTING MODEL OF THE SYNTHETIC INFORMATION ON TUWU AND YANDONG COPPER OREFIELD

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.
