摘　　要：西藏某斑岩型铜矿床是由西藏地质五队在班公湖-怒江成矿带发现的一个超大型规模的铜矿床。通过多个勘查阶段的投入,确定矿床呈隐伏状,矿石主要为原生硫化矿,少量混合矿,没有氧化矿,混合矿分布于矿体浅表,原生矿分布于混合矿之下。本文通过对该矿床铜物相样品结果进行分析,根据矿石的氧化程度类型划分标准,对矿床进行了“三带”划分,综合评定了该铜矿石的自然类型。The Tibet x porphyry-type copper deposit is a super-large-scale copper deposit discovered by the Tibet Geological Five Team in the Pangong Lake-Nujiang Metallogenic Belt.Through the input of multiple exploration stages,determine that the deposit is hidden,the ore is mainly primary sulfide ore,a small amount of mixed ore,No oxidation ore,Mixed ore is distributed on the superficial surface of the ore body,Primary ore is distributed under mixed ore.In this paper,the results of copper phase samples of the deposit are analyzed.According to the type of oxidation degree of the ore,the criteria are divided,the"three belts"division of the deposit was carried out,the natural type of copper ore was comprehensively assessed.
