摘要
冕宁后山滑石矿是国有老矿山,始建于上世纪70年代。随着矿山的开发,已有的资源量以近枯竭,寻找新的资源已迫在眉睫。该地区的滑石矿主要产于前震旦系登相营群大热渣组一段(Pt2dr1)地层的韧性剪切破碎带中。通过大量地质资料的研究,野外找矿及采样分析,圈定了四个滑石成矿远景区,评价了其资源潜力。
The Houshan talc deposit in Mianning was exploited in the 1970s. The talc deposit occurs in the ductile shearing zone of the First Member of the Darezha Formation of the Pre-Sinian Dengxiangying Group （ Ptzdr^1 ） . 4 prospecting targets for tale are delineated on the basis of a great amount of geological data. Their resource potential is assessed.
