摘要
利用镜下实测法和线性规划法统计了云南镇沅金矿区煌斑岩中矿物的实际含量。据此划分出该区煌斑岩岩石类型；总结出蚀变煌斑岩和矿化煌斑岩的过程中选岩矿物的变化规律；结合质量平衡计算，探讨了煌斑岩蚀交流体和矿化流体的性质。
By means of microscopic measurement and linear programming, the mineral contents of lampro-phyres in the Zhenyuan gold ore field, Yunnan Province, have been measured. According to the statis-tical data, this paper classifies the rock types of lamprophyres , summarizes the law of mineral variationfor lamprophyres in the processes of alteration and mineralization, and discusses the features and sourceof altering and mineralizing fluids.
