研究区属北秦岭金多金属成矿带,大店沟金矿床位于李子园-湘潭子新元古―晚古生代陆源裂陷火山-碎屑沉积岩带中,控矿因素主要有地层、构造。奥陶―震旦系李子园群是金矿床的赋矿层位,矿床分布受区域性元家坪―小寺沟韧性剪切带控制,NE向次级的韧性剪切带是重要的控矿构造,矿床类型为构造蚀变岩型。通过对本矿床成矿地质条件、控矿因素、矿化富集规律研究,总结了北秦岭地区地层、构造、岩体、围岩蚀变、地球化学异常等找矿标志,提出了该地区金矿勘查思路及找矿方向。

Dadiangou gold deposit is located in Liziyuan-Xiangtanzi volcano clastic sedimentary rock belt of continental rift of early proterozoic to late paleozoic,which belongs to the North Qinling Mountains gold polymetallic metallogenic belt.The ore controlling factors are mainly stratigraphic and structural.The de-posit belongs to structural altered rock type,which occur in Liziyuan group of Ordovician to Sinian,and dis-tribution controlled by territorial Yuanjiaping-Xiaosigou ductile shear belt,especially secondary NE direction ductile shear belt.Based on studies of the geological conditions,ore controlling factors,mineralization en-richment regularities of Dadiangou gold deposit,the prospecting criteria about of the stratum,structure, magmatite,wall rock alteration and geochemical anomaly have been established,and the exploration ideas and prospecting direction in the area have put forward.
