摘要
雄村矿区是西藏冈底斯斑岩铜矿带内已查明资源/储量达大型规模的Cu-Au矿区,已经发现了I、Ⅱ、Ⅲ号Cu-Au矿体。矿区地面磁测结果表明,矿区存在明显的高磁异常区和低磁异常区,两类异常区均有矿化显示,I号矿体位于低磁异常区,Ⅱ号矿体位于高磁异常区,磁异常特征的差异主要是因为磁铁矿含量显著不同造成的。通过对矿区地面磁测异常特征的研究,圈定出了2个低磁异常区和3个高磁异常区,综合地、物、化资料,对5个磁异常区今后的找矿思路进行了分析,为矿区及外围开展综合方法找矿提供了参考,同时,对于冈底斯斑岩铜矿带其它地段寻找该类型矿床具有十分重要的意义。
The Xiongcun mine is a large copper-gold deposit in the Gangdese porphyry copper belt of Tibet. The No. I,No. Ⅱ and No. Ⅲ Cu-Au ore bodies have been found in this district. The ground magnetic survey shows remarkable high magnetic anomaly zones and low magnetic anomaly zones,both present mineralization. The No. I ore body is located in the low magnetic anomaly zone and the No. Ⅱ ore body in the high magnetic anomaly zone,respectively. The different characteristics of the magnetic anomalies are caused by the significantly different magnetite contents. Based on the research of the anomaly characteristics of the magnetic anomalies in the Xiongucn district,two low magnetic anomaly zones and three high magnetic anomaly zones have been delineated already. Combining with geology,geophysics and geochemistry data,this work analyzes the ore prospecting potential of these five magnetic anomaly zones. It will provide a reference for ore prospecting by integrated approaches in the Xiongcun district and its peripheral areas. At the same time,it is also of importance for searching for deposits of the same type in the Gangdese porphyry copper belt.
