| 中文摘要: |
| 青海省都兰县三通沟北地区锰矿是东昆仑地区近年发现的一处海相沉积型锰矿,区内目前共发现5条锰矿化带,334矿石资源量482.48万t。锰矿体均位于中-新元古界万宝沟群碎屑岩组中,赋矿岩性为泥钙质粉砂岩,矿石类型主要为菱锰矿,少量褐锰矿,矿体明显受地层控制,走向及倾向上均较为稳定,但后期受到了辉长岩侵入体的不同程度破坏。本文通过对该锰矿体地质特征、控矿因素、矿床成因及找矿标志的研究探讨,认为该区及其周边的万宝沟群碎屑岩组具有较好的锰矿找矿前景。 |

| The manganese deposit in the north area of Santonggou in Dulan county is a marine sedimentary type manganese deposit first discovered in the East Kunlun area in recent years,Five manganese mineralization zones have been found in the area,The manganese ore bodies are all located in the clastic rock formation of the middle Neoproterozoic Wanbaogou group,The host rock is argillaceous siltstone,The ore type is mainly rhodochrosite,A small amount of brown manganese ore,The ore body is obviously controlled by the stratum,The trend and tendency are relatively stable,But later, it was destroyed by gabbro intrusions.In this paper, the geological characteristics, ore controlling factors, ore genesis and ore prospecting criteria of the manganese ore body are studied,It is considered that there is a good prospect of manganese ore prospecting in the clastic rock formation of Wanbaogou group in and around the area. |
