中文摘要:
      为评价某金矿深部找矿潜力及找矿靶区预测,文章采用构造叠加晕的找矿方法,通过系统的岩石地球化学分析及构造叠加晕理论模型的建立,对某金矿区主矿体(LM8)进行了深部找矿潜力评价和找矿靶区预测。文章以该金矿的成矿地质背景、成矿作用、成矿期次、矿床类型、矿床地质特征等作为基础资料,提出了该金矿床具有多阶段、多时期叠加成矿的特点,且矿体受NWW向韧性剪切带控制明显。研究结果表明:金矿区主矿体(LM8)深部存在盲矿体,且矿体延伸较大,经SDZK1901、SDZK1902钻孔验证,预测靶区找矿效果良好,显示了构造叠加晕找矿方法在该区域找矿方面具有良好的实用性,为区域金矿勘查提供借鉴意义。
英文摘要:
      In order to evaluate the deep prospecting potential of a gold mine and the prediction of prospecting target area, in this paper, the prospecting method of tectonic superimposed Halo is adopted, the deep prospecting potential and prospecting target area of a gold ore body (LM8) is evaluated by the systematic rock geochemical analysis and the establishment of the theoretical model of tectonic superimposed halo. Based on the Metallogenic geological background, mineralization, mineralization period, ore deposit type and geological characteristics of the gold deposit, this paper puts forward that the gold deposit has many stages and multiple periods of superimposed mineralization, and the ore body is controlled by NWW ductile shear Zone. The results show that:there is a blind orebody in the deep part of the main orebody (LM8) in the gold deposit, and the ore body is extended, which is verified by SDZK1901 and SDZK1902 borehole, and the prediction of the target area is good, which shows that the method of tectonic superimposed halo prospecting has good practicability in the area of prospecting and provides reference for the
