摘要
澜沧县糯鄙铜矿矿体呈薄层状、透镜状赋存于侏罗系中统花开左组第一段和第二段接触部位,矿床的形成与地层中萃取的含铜热卤水有关;矿体具有明显的层控特征,产状与岩层产状基本一致,且与围岩界线不明显,局部受一定的构造控制,后期断裂对成矿有一定的改造作用,矿床成因类型为沉积-改造型。
The orebody of Nuobi Cu deposit in Lancang is thin bedded,lenticular in contact place of Upper Jurassic Huakaizuo Formation Menber 1 and Menber 2.The metallogenesis is in relation to the Cu-bearing hot brine abstract from the strata.The orebody has the clear stratabound feature,occurrence consists with that of rock bed,boundary with wall rock not clear,locally controlled by a certain structure,the later fault has a certain reformation of metallogenesis,which is the sedimentation-reformation deposit in genesis.
