构造叠加晕研究在平度市大庄子金矿床深部找矿中的应用及探讨

摘要

通过对平度市大庄子金矿床矿床特征和地球化学特征的分析,论述了矿区构造叠加晕特征：大庄子金矿床具有多期多阶段叠加成矿成晕以及多种形式叠加的特点。根据其叠加晕特征,建立了大庄子金矿床深部第二富集带预测及构造叠加晕理想模式,确定了矿区深部盲矿预测标志以及找矿标志,并提出预测靶位,且在预测靶位取得了良好的找矿效果。%Through analysis on deposit characteristics and geochamical characteristics of Dazhuangzi gold deposit in Pingdu city,characteristics of structural superimposed halos in this mine area are discussed.Dazhuangzi gold deposit has the characteristics of multiple-periodic superimposed ore-forming and various forms of overlay.According to the characteristics of superimposed halos,ideal model of second concentration belt predication and structural superimposed halos in deep part of Dazhuangzi gold deposit has been established.Prospecting criterias of blind ore mining and predicated signs in deep part of this deposit have been identified,and has achieved good ore prospecting effects.
