摘要
通过对凤凰山铜矿床新的矿化类型—斑岩型铜矿体的系统采样分析,认为斑岩型铜矿体具有各自的原生晕分带性;多阶段矿化作用和多矿体的迭瓦状产出,使各阶段矿化作用和各矿体的原生晕叠加形成了统一的、范围较大的、较为稳定的原生叠加晕。因此,矿体的原生晕和原生叠加晕特征可指导本区斑岩型铜矿体的成矿预测。
Through the systematic sample collection and the analysis of the new metallizing type porphyry copper body in Fenghuangshan copper deposit, it is recognized that every porphyry copper body has its own zoning of primary halo. The unitary, larger scaled and the more steady primary overprint halo were formed by the primary halo of multi--metallizing phases and the imbricate porphyry copper bodies. Therefore, the characteristics of primary and primary overprint halo have some guide significance in metallogenic prediction of porphyry copper bodies in this area.
