胶东西北部黄埠岭金矿床两期次叠加成矿

黄埠岭金矿床位于胶东西北部招莱金矿带，产于北东向黄埠岭-凤凰山断裂的上盘，由18条大小不一的金矿脉组成。研究表明，北东向断裂控制早期中深成金矿成矿，北北东向断裂控制晚期浅成金矿成矿。早晚两期金矿化不同，早期中深成金矿以石英、黄铁矿、辉钼矿、银金矿、自然金、黄铜矿、闪锌矿和方铅矿等组合为特征，晚期浅成金矿以石英、方解石、银金矿、自然银、硫盐矿物和胶黄铁矿等组合为特征。早晚两期成矿叠加部位构成矿区内富矿段。

Two Phase Overprinting Mineralization in Huangbuling Gold Deposit in Northwestern Jiaodong Peninsula

Huangbuling gold deposit locates in the Zhaoyuan-Laizhou gold deposit belt in Northwestern Jiaodong peninsula,at the hanging wall of the Huangbuling-Fenghuangshan NE trending fault.It consists of 18 ore veins with different scales.The study shows that the NE faults controlled the early stage intermediate gold vein,and the NNE faults controlled the late stage shallow gold vein.The early phase mineralizations are different from late phase.The early stage intermediate gold deposit consists of quartz,pyrite,molybdenite,electrum,gold,chalcopyrite,sphalerite,galena and others;while the late period gold deposit consists of quartz,calcite,pyritogelite,electrum,silver,sulfosalt minerals and others.The overprinted part of the early and late stages is the ore shoot part in the ore area.
