摘要
云南永善县韩家沟铁矿矿体赋存于二叠系上统宣威组(P2x)底部砂岩、页岩地层中,单个小矿体呈透镜体或条带状产出,矿石主要为赤铁矿石,矿体与围岩接触界面清楚。矿床成因属沉积-改造型矿床,硅化、黄铁矿化、碳酸岩化及层间破碎带等是找矿的直接标志。
The orebody of Hahjiagou Fe deposit in Yongshan,Yunnan is in Upper P Xuanwei Formation(P2x)bottom sandstone and shale.The single small orebody is lenticular,striped.The main ore is hematite.The contact between orebody and wall rock is clear.It is a sedimentary-reformation deposit in genesis.The silicification,pyritization carbonatization and interlayer fracture zone,etc are the direct prospecting criteria.
