招平断裂带南段南墅金矿地质特征及成矿远景

南墅金矿床位于胶西北著名金矿成矿带——招平断裂带的南段,南北与下庄、山后金矿相邻,NW向断裂与招平断裂带在矿区北部交会,成矿条件十分优越。近年来青岛地质工程勘察院在该区勘查取得了新进展,在矿床深部新发现一个产状稳定金矿体,最大埋深约700m,探获金矿资源量规模达到中型,沿走向、倾向均未封闭,进一步勘查资源潜力较大。该文详细叙述了矿床地质特征,总结了矿体产出及矿化富集规律,分析了南墅金矿的成矿远景,提出了该区及招平断裂带南段金矿勘查的找矿建议。

Geological Characteristics and Metallogenic Prospects of Nanshu Gold Deposit in the South of Zhaoping Fault Zone

Nanshu gold deposit is located in the southern section of Zhaoping fault zone, which is a famous gold mineralization belt in northwest Jiaodong area. This gold deposit is adjacent to Xiazhuang and Shanhou gold deposit in the south and north area. The fault with the trend of NW and Zhaoping fault zone will meet in the north part with very superior metallogenic conditions. In recent years, new progress of gold exploration in this area has been made by Qingdao geoengineering exploration institute. A gold ore body with stable attitude has been found in the deep part. The largest depth of the ore is 700m, and the accumulated reserves of gold deposits has been up to a medium size. The scale of ore body is not controlled in strike and tendency, and it is expected to be a large reserve scale deposit with further exploration. In this paper, geological characteristics of Nanshu gold deposit has been introduced in detail, occurrence and mineralization enrichment rule have been summarized, and metallogenic prospect has been analyzed. It will provide some references for the exploration and research in the southern section of Zhaoping fault zone.
