威海市范家埠金矿床矿石特征与成矿作用研究

Weihai Fanjiabu gold deposit ore characteristics and mineralization

威海东部地区是山东省重要的金及多金属矿有利成矿区,范家埠金矿床是威海东部规模最大的典型含金石英脉型金矿床。范家埠金矿的矿石类型为脉状、网脉状黄铁绢英岩化碎裂岩型,细脉浸染状多金属硫化物石英脉,团块状、块状硫化物石英脉型三种类型。文章主要通过论述范家埠矿区矿床地质特征、矿石的矿物组成及结构构造、矿石类型等探讨成矿作用,为威海东部地区金矿找矿及金矿研究提供依据。

The eastern part of Weihai is an important gold and polymetallic ore deposit in Shandong province. The Fanjiabu gold deposit is the largest gold bearing quartz vein type gold deposit in the eastern part of Weihai. Fanjiabu gold type ore vein andstockwork beresitization cataclastic rock type, veinlet polymetallic sulfide quartz vein, lumpy, massive sulfide quartz vein type three types. This paper mainly discusses the metallogenic characteristics of ore deposits in the area of ore deposits, including mineral characteristics, ore composition, structure and ore types, and provides a basis for gold prospecting and gold research in the eastern part of Weihai.
