| 摘 要： | 南冷放段金矿体赋存于张家口金矿主脉带中，但成因与张家口金矿矿体明显不同，金矿全的形成和分布这ＳＮ向断裂及其ＮＷ向羽状分支构造控制。根据矿石自然类型要带，可划人灵原生含金硫化物石英脉型、原生含硫化物钾长石石英脉型和氧化矿体３个带，分别为近ＳＮ向断裂及其ＮＷ向状分支构造所围限，在Ｆ４断层东盘依次出现，氧化程度逐渐增高。

| Abstract: | Gold orebody of Nanlenggou ore block is occrred in the main lode belt of Zhangjiakou gold deposit. However, the genesis of the gold orebody is obviously different from that of Zhangjiakou gold deposit. The formation and distribution of the gold orebody are structurally controlled by the near SN trending fault and its feathered NW trending branching fault. According to the zonation of physical types, the orebodies can be divided into three belts which are original gold bearing sulfide quartz vein, original gold bearing sulfide K feldspar quartz vein and oxidized type. They are respectively confined by near SN trending fault and its feathered NW trending branching structure and successively occurred in the east side of fault F 4. The oxidized level of the orebodies is gradually raised. |
