板石沟铁矿赋存于晚太古宙表壳岩系中段角闪质岩石中,其原岩应属中基性火山喷出岩。矿体受北东东向复式向斜构造控制,两翼形成南北两条含矿带,并被同一磁异常所套合。各矿组深部具备连续性赋矿因素,预测各矿组之间存在着隐伏矿体。
闆石溝鐵礦賦存于晚太古宙錶殼巖繫中段角閃質巖石中,其原巖應屬中基性火山噴齣巖。礦體受北東東嚮複式嚮斜構造控製,兩翼形成南北兩條含礦帶,併被同一磁異常所套閤。各礦組深部具備連續性賦礦因素,預測各礦組之間存在著隱伏礦體。

Banshigou iron occurs in hornblende rock of the middle member of late Archaean Eon supracrustal rock,its protolyte is intermediate-basic eruptive rock.NEE synclinorium controls the orebody,the two slopes of synclinorium format the two ore-bearing zones of south and north,the location of them is consistent with that of magnetic anomaly,each sub-orebody in depth may successive,between sub-orebody and the others may exist concealed orebody by inference.
