摘    要：黄埠岭金矿床是招莱金矿带内典型的脉型金矿床之一。研究表明,该矿床矿石中金主要是以显微可见的金银系列矿物,呈裂隙金、包裹金和粒间金产于黄铁矿、石英、黄铜矿、方铅矿、闪锌矿、钾长石和硫盐矿物等之中。金矿物主要富集在早期金矿化的二、三成矿阶段和晚期硫盐矿物富集阶段。这一特征与区域招莱金矿带内其他金矿床相比较,该矿床具有晚期金与硫盐矿物共生富集特征,证明该矿床存在两期金矿化。

Abstract: Huangbuling gold deposit is one of the typical vein type gold deposits in Zhaolai gold deposit belt.Researches show that as microscope-visible gold and silver series minerals,gold bears in pyrite,quartz,chalcopyrite,galena,blende,potash feldspar and sulphide mineral in the terms of fissure gold,inclusion gold and intergranular gold.Gold minerals mainly enriched in the early stage second and third gold mineralization phase and the late stage sulphide mineral enrichment phase.Comparing to other gold deposits in Zhaolai gold deposit belt,the deposit has the characteristics of late stage syngenesis and enrichment of gold and sulphide minerals,which proves there were two stages of gold mineralization.
