| 摘 要： | 破碎蚀变岩型金矿与裂隙充填石英脉型金矿是栖霞地区主要金矿化类型，破碎蚀变岩型金矿分布于郭家岭超单元西石硼单元或玲珑超单元郭家店单元二长花岗岩体内外接触带附近；而裂隙充填石英脉型金矿主要分布于栖霞-桃村一带的古老基底构造轴部附近，且集中分布于该地区南北宽不超过20km的范围内。而大部分含金矿脉其附近往往发育有成群成带的中基性岩脉，中基性岩脉特别是煌斑岩为该区找金的一个间接标志。

| Abstract: | Fractured alteration rock - type gold deposits and fractured rifling quartz vein - type gold deposits in Qixia area are major gold mineralization types. Fractured alteration rock -type gold deposits distributed in Xishipeng unit of Guojialing superunit or in the contacting zones of monzonitic granite in Guojiadian unit of Linglong superunit. Fissured filling quartz vein - type gold deposits mainly distributed in ancient basement axis in Qixia - Taocun area, and concentrated within the scope of 20km from north to south part. Mostly, gold ore - beating veins will occur in groups in gold - bearing veins , which is an indirect symbol for exploring gold ore in medium - basic rock veins, especially in lamprophyres. |
