摘要:
大尹格庄金矿床位于招平断裂带中段，为一特大型蚀变岩型金矿床，招平断裂带为主要容矿构造。后疃矿区位于大尹格庄金矿床Ⅱ号矿带外围，是本次伽玛能谱面积测量和Ⅱ号矿带深边部找矿预测的工作区。后疃矿区成矿期张性断裂活动和热液成矿作用在矿体上盘胶东群变质岩围岩中留下了蚀变及钾、铀、钍等放射性元素异常等成矿热液活动痕迹，为伽玛能谱法找矿提供了依据。根据后疃矿区伽玛能谱异常规模、强度、组合特征等，共圈定找矿靶区8处。其中，A-1、B-1、B-3和C-3找矿靶区经钻探工程验证并先后见矿，取得了后疃矿区深边部找矿的重大突破。

Abstract:
The Dayingezhuang Gold Deposit is located in the middle section of the Zhaoping fault zone and is a large-scale altered rock-type gold deposit,with the Zhaoping fault zone being the main ore-hosting structure.The Houtuan Mining District is located on the outskirts of the II ore zone of the Dayingezhuang Gold Deposit and is the working area for gamma spectrometry area measurement and deep and peripheral prospecting of the II ore zone.The Houtuan Mining District has experienced extensional fault activity and hydrothermal mineralization during the ore-forming period,leaving behind alteration and anomalies of radioactive elements such as potassium,uranium,and thorium in the host rocks of the Jiaodong Group,providing a basis for gamma spectrometry ore prospecting.Based on the scale,intensity,and combination characteristics of the gamma spectrometry anomalies in the Houtuan Mining District,a total of 8 prospecting targets have been delineated.Among them,the A-1,B-1,B-3,and C-3 prospecting targets have been verified by drilling projects and have successfully discovered gold deposits,achieving significant breakthroughs in deep and peripheral prospecting of the Houtuan Mining District.
