摘要
本文通过对七步郎铜矿床含矿层位、容矿岩石类型、构造及地球化学和成矿特征等综合分析、研究，从铜矿化的时、空结构特征两方面框定了控矿的主导因素，探讨了成矿富集规律，提出只有经历初始预富集→预富集→构造改造富集完整序列阶段的区段方能形成富矿体的认识。对成矿预测有重要实际意义。
In this paper,by comprehensive analysis and study of the characteristics of ore-bearing horizon, type of ore-holding rock,structure,geochemistry and metallogenesis of the Qibulang Cu deposit,the principal factors of ore-contorlling in time and space of Cu metallogenesis are determined and the metallogenetic enrichment regularity is discussed.It is pointed out that the rich orebody can be formed only in the section experienced the complete succession of initial preenrichment-pre-enrichment-structural reformation enrichment.This viewpoint has the practical significance in metallogenetic prognosis.
