摘　　要：剖面原生叠加晕研究结果表明,凤凰山铜矿床北区经历了多阶段的成晕成矿作用,各矿体各阶段的成晕成矿作用具有各自的原生晕分布特征,原生晕的叠加基本没有改变这种特征,只是形成了一个范围更大、强度更弱的原生叠加晕;同时,本区原生晕分布特征也指示了深部存在隐伏矿体的可能性。The study results on sectional primary overlap halo indicated that in the north of Fenghuangshan copper deposit,the halo and ore-body are formed at multi-stage.Every stage of halo forming and orebody forming has its own distribution characteristics of primary halo.The overlap of primary halo basically does not change its characteristics,just forming a larger scale and weaker strength primary overlap halo.And then,the distribution characteristics of primary overlap halo in this area indicate the possibility of concealed ore-body existing in deep area.
