摘要
雄村矿区是西藏冈底斯斑岩铜矿带内已查明资源(储量)及规模达大型的铜金矿区,最早发现Ⅰ号Cu-Au矿体,其后发现了Ⅱ、Ⅲ号Cu-Au矿体。化探异常在Ⅱ、Ⅲ号矿体的发现和初期勘查中起到了至关重要的作用,尤其是在发现和圈定Cu-Au矿找矿靶区中提供了重要线索。通过分析Ⅱ、Ⅲ号矿体勘查工作中的化探异常特点及作用,旨在为应用化探异常指导找矿工作提供参考作用,同时,对于冈底斯斑岩铜矿带其他地段寻找该类型矿床,具有十分重要的意义。
The Xiongcun ore district is a large copper-gold ore district in the Gangdise porphyry copper metallogenic belt of Tibet. The No. Ⅰ copper-gold orebody is the earliest discovered orebody in the Xiongcun ore district,followed by the discovery of No. Ⅱ and No. Ⅲ copper-gold orebodies. Geochemical anomalies played a key role in the discovery and preliminary exploration of No. Ⅱ and No. Ⅲ orebodies,and gave important clues to finding the copper-gold exploration area. This paper deals with the characteristics and roles of geochemical anomalies in the exploration of No. Ⅱ and No. Ⅲ orebodies for the purpose of providing references for future prospecting. The summarization of the geochemical prospecting criteria for these deposits is very important in search for the same type of deposits in the Gangdise porphyry copper belt.
