胶东夏甸道北庄子金矿床严格受招平主干断裂带的控制,具有多期次多阶段叠加成矿的特征.本文以矿区27号和30号勘探线为研究对象,开展构造叠加晕元素地球化学分析,结果表明:单一期次矿体原生晕轴向分带序列为As、Sb、Hg(前缘晕)→Au、Ag、Cu、Pb、Zn(近矿晕)→Bi、Mo、W(尾晕),在矿体下部出现前尾晕共存现象,分析元素分布规律建立矿体构造叠加晕模式,结合其盲矿预测标志,在30勘探线预测靶位1处,指示深部矿体持续延伸,为后期深部找矿勘查工作提供重要的参考.
Study on Tectonic Superimposed Halo of Daobeizhuangzi Gold Deposit in Xiadian Gold Mine in Jiaodong Area
Daobeizhuangzi gold deposit in Xiadian area in Jiaodong peninsula is strictly controlled by Zhaop-ing main fault zone.It has the characteristics of multi-stage and multi-stage superimposed mineraliza-tion.In this paper,the element geochemistry of the structural superimposed halo samples from No.27 and No.30 exploration lines in the mining area has been studied.It is showed that the axial zonation sequence of primary halo formed in a single stage of mineralization is As,Sb,Hg(leading halo)→ Au,Ag,Cu,Pb,Zn(near ore halo)→ Bi,Mo,W(tail halo).The phenomenon of coexistence of leading halo and tail halo occurs in the lower part of the ore body.Combining with the established structural superimposed halo model and blind ore prediction markers,one target location has been predicated in No.30 exploration line.It is indicated that ore bodies extend to the deep.It will provide an important reference for later deep ore prospecting and exploration.
