摘要
综合研究易门铜矿区钴、铜一钴矿床的矿化围岩及蚀变、矿石与脉石矿物组合、矿体地质特征等，提出易门铜矿区的钴矿化形成于晋宁期或印支—燕山期与隐伏的中—酸性岩体有关的后生叠加岩浆期后热液作用，还指出找矿方向，注意在隆起（背斜）与断裂构造的发育区，硅化、钠化、黑云母—绿泥石化蚀变带及Ｃｕ、Ｃｏ（Ａｕ）、Ａｓ、Ｐｂ、Ｚｎ化探异常的地段，优先找矿评价，扩大钴、铜—钴矿床的远景。
The characteristics of mineralized wallrock and altered mineral associations of ore minerals and gangues,and geology of orebodies in the cobalt,copper cobalt deposits are comprehensively studied in the Yimen copper district.It is suggested that the cobalt mineralization in the Yimen copper district was formed by post magmatic hydrothermalism from epigenetic superimposition related to the hidden intermediate acidic rock bodies in Jinning epoch or Indosinian Yanshanian epoch.Further prospecting directions for cobalt and copper cobalt deposits are also pointed out.
