摘　　要：岩矿鉴定法是采用偏反光显微镜,对岩石矿物的各种光学参数进行测定,是鉴定岩石矿物的重要手段。通过岩矿鉴定法对某锰矿区系列样品鉴定分析,得出岩矿鉴定法能够快速、准确的确定矿物及岩石名称,并且直观的观察到矿物成分、结构、构造的变化,但对于隐晶质矿物、某些相似矿物亚类的识别,岩矿鉴定法依然存在不足。Rock-mineral determination is used in the polarizing microscope measure optical parameter of the rock-mineral,as is the important means of measure the rock-mineral.In this article,the author analyzes a manganese ore zone rock,by using rock-mineral determination.It concludes that rock-mineral determination can be quickly and accurately determined in the name of minerals and rocks.We can observe the change of mineral composition, texture and structure.But for cryptocrystalline minerals,some similar mineral types identification used in rock-mineral determination is difficult.
