摘　　要：随着找矿难度的日益加大和各种矿产预测理论的不断完善,应用综合信息矿产预测理论方法圈定靶区、寻找隐伏矿体越来越广泛且效果明显.在广泛收集、研究前人工作成果的基础上,重新厘定八家子-吴家屯多金属矿田综合信息找矿模型,并将其转换成地质变量,在已构置的网格单元中依据综合变量进行赋值.以GIS为平台进行空间分析和叠加,采用综合信息矿产预测的理论与方法,开展矿田的综合信息矿产预测,得到4个综合信息得分高值区(即靶区),对矿田的进一步找矿具有一定的指导意义.With increasing difficulties in prospecting, the method of comprehensive information for concealed ore searching and target delineation is broadly applied with support of different mineral prognosis theories. On the basis of collection and study of previous achievement, this paper re-defines the comprehensive information prospecting models for the Bajiazi- Wujiatun polymetallic orefield by conversion of geological variables. The grid units are valued according to comprehensive information. With GIS-based spatial analysis and superposition, adopting comprehensive information ore predicting theory and method, 4 high-score zones are obtained as targets, which would be significant guidance for further prospecting in the orefield.
