| 摘 要： | 贡北金矿床位于西倾山隆起带南侧 ,隶属于天水—达拉—南坪东区域成矿带上的贡北—格尔托成矿带 ,是大水金矿床外围的小矿床。通过化探、钻探工作 ,并与大水金矿进行对比 ,认为均属于一个以低温热液作用为主的金矿带。已知低温金矿体和矿化异常区沿区域性断裂方向展布 ,分布集中 ,成群结集呈串珠状分布。推测贡北矿区在已知矿体的中深部找矿潜力很大 ,应在该矿区东部 3983 0m高程点南一呈岩枝状产出的花岗闪长岩体附近开展进一步的找矿工作。

| Abstract: | Gongbei gold ore deposit is located at south side of Xiqingshan mole track ,and it is in Gongbei-Gertuo metallogenic zone of Dashui-Dala-Nanpingdong regional metallogenic belt.This ore deposit is a peripheral small one of Dashui gold ore deposit.Through Geochemical exploration,drilling and contrast with Dashui ore deposit,we think of that they belong to same gold metallogenic belt dominating epithermal action.All knew epithermal gold orebodies and minerlization anomalies,their distribution is along with the direction of regional foults and take the shape of moniliform.On the basis of inference,there is great potential at deep of knew ore bodies in Gongbei ore district.In the east of it,at the level of 3 983.0m, there is a granodioritic apophysis,we think that nearby it,can carry out ore-hunting further there. |
