陕西勉略宁地区火峰垭金矿矿床地质特征及矿床成因分析

Geological Features and Metallegenic Genesis of Huofengya Gold Deposit in Mianluening Region,Shanxi

陕西勉略宁地区火峰垭金矿矿床位于中上元古界碧口群内,区内韧性剪切带发育明显,并控制了主要金矿体的发育。该区主要矿石类型包括石英脉型金矿以及蚀变细碧岩型金矿。通过对金矿床地质特征的研究,特别是控矿地质要素分析,总结火峰垭金矿床成矿特征,认为火峰垭金矿为火山沉积-后期构造热液成因金矿床。

Huofengya gold deposit occur in upper Proterozoic Bikou group of Mianluening district, Shanxi province. Ductile shear zone is extremely developed in this area, and it always control the gold orebody distribution. There are two main ore types in this area, one is quartz vein type and another is alter-spilite type. This paper focus on the ore-forming geological features, especially the ore-controlling factors, Then it can be concluded that the genesis type is volcanic-sediment and postaltered hydrothermal deposit.
