云南东川白锡腊铜矿倒转背斜控矿意义

THE ORE CONTROL SIGNIFICANCE OF REVERSED ANTICLINE OF BAILAXI CU DEPOSIT IN DONGCHUAN,YUNNAN

倒转背斜控制矿体在空间的分布。南东翼为典型的东川式层状铜矿体,核部为中老龙层状角砾岩型铜矿体,推测北西翼亦为东川式层状铜矿体。根据背斜两翼对应关系,认为背斜北西翼(正常翼)具有较好的找矿前景。

The distribution in space of orebody is controlled by the reversed anticline. The typical bedded Cu orebody of Dongchuan type is on the SE limb. The Zhonglaolong bedded Cu orebody of breccia type is in the core. We infer that there is the bedded Cu deposit of Dongchuan type on the NW limb as well. According to the cor- respondence of 2 limbs, we think that the NW limb （normal limb） must have the better prospecting potentiality.
