摘　　要：三台子地区位于南秦岭武当隆起区内德胜-鲍峡金银多金属成矿带,区内成矿地质条件优越,通过开展1∶1万土壤地球化学剖面测量,共圈定出2处Au异常高值区,部分异常区显示出规模大、强度高以及连续性和组合性好的特征;进一步的探槽工程揭露情况显示,三台子地区金矿化赋存于武当群片岩中,与区域构造活动密切相关。综合考虑地球化学异常特征、区域成矿地质背景和矿区地质特征,本文认为三台子地区具备很好的金找矿潜力。The Santaizi Area is located in the Desheng-Baoxia Au-Ag polymetallic metallogenic belt of the Wudang uplift,South Qinling Mountains,where the geological conditions for mineralization are favorable.Based on 1∶10,000 soil geochemical profile surveys,two Au anomalous high-value zones have been determined.Some anomalies are characterized by large scale,high intensity,good continuity and combination.Further trenching exposures revealed that the Santaizi gold ore bodies occur in the schists of the Wudang Group and are closely related to regional tectonic activities.Integrating the geochemical anomalies,regional metallogenic setting and geological features of the ore deposit,this paper proposed that the Santaizi area has great potential for gold prospecting.
