摘　　要：北杨庄金矿位于秦岭造山带东段。在系统收集区内已有地质成果资料的基础上,结合实地工作,总结了金矿床地质特征。通过与区内典型造山型金矿床进行类比,认为该矿床受到地层和构造双重控制,成矿物质来源于地壳深部和上地幔,成矿物质来源、成矿时代以及矿体的赋存空间位置等均与秦岭造山作用相关,与老湾、上上河金矿成矿特征类似,属造山型金矿床,矿区边深部具良好找矿前景。Beiyangzhuang gold deposit is located in the eastern part of Qinling orogenic belt.Based on the systematic collection of geological achievements and data in the area,combined with on-site work,the geological characteristics of the gold deposit were summarized.By analogy with typical orogenic gold deposits in the area,it is considered that this deposit is controlled by both strata and structure,and the ore-forming materials come from deep crust and upper mantle.Ore-forming materials source,ore-forming time and ore-body spatial location are related to Qinling orogeny,similar to Laowan and Shangshanghe gold deposits,belongs to orogenic gold deposits and the deep side of the mining area has a good prospecting prospect.
