| 摘 要： | 通过几年的野外勘查工作,大水沟矿区在找矿方面取得了较为显著的成果,矿区内圈定了2处水系沉积物综合异常,通过异常查证,目前发现了3条矿化蚀变带,圈出金矿体5条、铜矿体1条、钼矿化体1条、铅锌银矿化脉1条。其中金矿体主要赋存于蚀变的碎裂岩中,对发现的矿体沿走向进行了槽探揭露、钻探深部验证控制,矿体沿走向、倾向具一定延伸,深部品位变富,与邻近五龙沟金矿田具有相似的成矿地质背景及成矿规律,说明该矿区具有较大的找矿空间。

| Abstract: | Through years of field exploration, significant progress was made at Dashuigou mine. ＇lwo comprehensive stream sediment anomalies were delineated. By abnormal verification, three mineral- ized alteration zones, five gold bodies, a copper body, a molybdenum mineralized body and a lead- zinc-silver mineralization veins were discovered. Gold ore bodies mainly occurred in the altered rock fragments. Further trenching and deep drilling along strike revealed that ore body had a certain tend- ency and enriched with depth. Dashuigou mine had a similar geological setting and metallogensis with adjacent Wulonggou gold field, indicating that the mine has a large ore prospecting. |
