大比例尺成矿预测的基础是深入研究成矿地质背景、成矿因素和矿化标志，重点剖析和认识区内的矿化局部富集特征和以控矿构造为重点的矿体空间定位规律（王庆乙，王敬尧，１９８７）。（１）成矿地质背景分析的理论与新认识成矿带总是位于一种或几种在成矿中起不同作用的地... The basis of large-scale ore-forming prediction is to deeply study the metallogenic geological background, metallogenetic factors and mineralization markers, and to focus on analyzing and understanding the mineralization local enrichment features in the area and the orebody spatial positioning law Wang Qingyi, Wang Jingyao, 1987). (1) Theory and new understanding of metallogenetic background analysis Metallogenic belt is always located in one or several places that play different roles in mineralization.
