| 摘 要： | 河东金矿位于焦家矿田内 ,属蚀变岩型金矿 ,矿床受望儿山断裂控制 ,矿体沿断裂带平行产出 ,上下盘围岩分别为玲珑型花岗岩和郭家岭似斑状花岗闪长岩。蚀变带由上至下出现绢英岩化花岗质碎裂岩、绢英岩、绢英岩化花岗闪长岩 ,金矿体赋存在强蚀变岩中。一般认为河东金矿的各矿体产于断裂带下盘部位 ,但本文研究认为 ,河东金矿的矿体确切地说应该位于两条主断裂之间的部位 ,尤其是组成菱形结环的分叉或汇合部位 ,河东金矿的1～ 10号矿体全部落于两断裂之间

| Abstract: | Hedong gold deposit, an alteration type gold deposit in Jiaojia gold mine field, is controlled by Wang'ershan fault zone and contacts to Linglong type granite and Guojialing type granodiorite at the up wall and foot wall respectively. From up to below, the alteration zone is divided into phyllic alteration granitic fragmented rock,phyllic alteration rock, phyllic alteration granodiorite,and the gold ore bodies are just host in the seriously altened rock.Different from the view suggesting that the ore bodies are situated below the fault plane,author believe that they are hosted between the two main faults, especially in the open portion of lozenge shaped knot in Hedong area. |
