摘　　要：黑云母二长花岗岩的镜下照片。黑云母二长花岗岩镜下照片是经过样品前处理后在显微镜下拍摄的照片,照片显示该岩石是由斜长石、钾长石、石英、黑云母、少量白云母组成。岩石镜下照片不仅可以鉴定岩石的主要矿物组成,还能分析矿物成生序列、结构、构造和蚀变特征等,对地下空间资源开发利用和地热地质研究具有重要意义。Microscopic photograph of biotite monzogranite.This photo-graph of biotite monzogranite was taken through a microscope after sam-ple pretreatment.It shows that the rock is composed of plagioclase,potassium feldspar,quartz,biotite,and a small amount of muscovite.A microscopic photograph of a rock can not only identify the main mineral composition of rocks but also analyze the formation sequence,texture,structure,and alteration characteristics of minerals,which is of great significance for the exploitation and utilization of underground space resources and the study of geo-thermal geology.
