摘要
应用光学显微镜和Qwin图像分析系统 ,对风化花岗岩的微观结构进行了定量分析 ,介绍了包括含量、粒度、方向孔隙度、形状系数、定向性等定量指标。根据分析的结果指出 ,香港地区九龙观塘花岗岩为中风化至强风化细粒花岗岩 ,石硖尾花岗岩为强风化粗中粒花岗岩。
A quantitative analysis of microstructure of weathered granite under optical microscope by using Qwin's image processing system is done in the paper and quantitative indexes, such as content, grain size, orientrf porosity, shape factor etc. are listed. According to the analysis result, the granite in Kwun Tong is moderately weathered fine-grained granite, and the granite in Shek Kip Mei is highly weathered coarse-medium-grained granite.
