摘要
为适应地球化学分带的复杂性，定义了叠加分带序列和矿化阶段分带序列的概念，提出了叠加分带序列分解及叠加矿化性质识别方法。在胶东山城金矿岩石地球化学勘查中该方法获得成功的应用。揭露了该矿区已知矿体的常规分带序列中隐含的两种矿化叠加性质：１号脉为无工业意义的矿化叠加；８号脉则主要为下部隐伏矿体的叠加，并已得到后期勘探验证。
To analyse the complexity of geochemical zoning, the concepts of superposed zoning sequence and mineralization stage zoning sequence are defined,and a new method to decompose the superposed zoning sequence and recognize the superposed mineralization natures is suggested. The method has been used successfully for petrogeochaemical exploration in Shancheng gold deposit Jiaodong. Two types of superposed mineralization natures from usual zoning sequence of known orebody are revealed:vein No.1 is only superposed by invaluable mineralization, vein No.8 is mainly superposed by blind orebody and it is confirmed by latest exploration.
