山东栖霞笏山-西陡崖金矿地质特征及资源潜力分析OA
Analysis on Geological Characteristics and Resource Potential of Hushan—Xidouya Gold Deposit in Qixia City in Shandong Province
栖霞笏山-西陡崖金矿位于蓬莱-栖霞金成矿带南侧,是产于新太古代变质基底与中生代燕山期花岗岩接触带附近的破碎蚀变岩型金矿.本次研究在矿区外围开展了详细的野外地质调查,并对该矿床进行了详细研究,在Ⅰ号主矿体深部施工DKZK03钻孔,控制金矿体4层,累计真厚度6.85m.其中,Ⅰ-1、Ⅰ-2号金矿体埋深分别为1273.80～1275.45m、1072.95～1076.55m,Ⅰ-1号金矿体为该区目前最深金矿体.采用趋势外推法对区内深部金矿体进行定位预测,为今后在栖霞地区金矿深部找矿勘查提供了依据,该地区金矿深部具有较大的找矿潜力.
Hushan-Xidouya gold deposit in Qixia city in Jiaodong area is located in the south of Penglai-Qixia gold metallogenic belt.It is a crushing altered rock type gold deposit occured in the contact zone be-tween Neoarchean metamorphic basement and Mesozoic granite.A detailed field geological survey has been carried out in the surrounding areas,and the deposit has been studied as well.DKZK03 borehole has beem laid in the deep part of No.1 main ore body,and 4 layers of gold ore bodies have been controlled,with a cumulative true thickness of 6.85m.Among them,the buried depths of No.Ⅰ-1 and Ⅰ-2 gold ore bodies are 1273.80～1275.45m and 1072.95～1076.55m respectively.The Ⅰ-1 gold ore body is currently the deepest in the area.The trend extrapolation method is used to locate and predict the deep gold deposits in the area.It will provide a basis for future exploration and exploration of gold deposits in Qixia area.The deep gold deposits in the area have great potential for exploration
