摘　　要：随着找矿难度的日益加大,如何运用高新技术对海量的地、物、化、遥地学多源信息进行"二次开发"和"综合应用",提高找矿成功率,降低成本,已成为地质勘查领域亟待解决的问题。本文通过对北衙金矿的研究,在广泛收集、研究前人工作成果的基础上,厘定了北衙金矿综合信息找矿模型。以GIS为平台,对矿区积累的地、物、化多源信息进行了空间分析和叠加,采用综合信息成矿预测的理论与方法,开展了矿区的综合信息成矿预测,得到四个综合信息得分高值区,圈定找矿靶区6个,对矿山下一步的找矿具有重要的指导意义。With increasing difficulties in prospecting, it has become an urgent issue in geological prospecting how to realize redevelopment and com- prehensive application using the high and new technology to flood information of geology, geophysics, geochemistry and remote sensing, to enhance pros- pecting success ratio, and ultimately to reduce costs. Based on collection and research of previous work, we have constructed an ore-search model for the Beiya gold deposit using comprehensive information. For this model, we have performed spatial analysis and stacking of various data on this mine from geol- ogy, geophysics and geochemistry on the GIS platform. Then we used this model to make a metallogenic prognosis of the ore district, resulting in 4 high- score zones of comprehensive information and delineated 6 targets, which would be of great guidance significance for further prospecting in this mine.
