摘　　要：岩矿鉴定是矿床学和成矿规律研究的重要组成部分,对分析含矿热液演化过程以及建立成矿模式等意义重大。本文以斑岩型矿床和矽卡岩型矿床分别分析了岩矿鉴定工作在光片和薄片鉴定中的应用,研究表明:通过薄片鉴定可得出金属矿化与围岩蚀变之间的关系;通过光片鉴定可得出不同矿物之间的晶出先后顺序,也可得出同一金属矿物的不同期次;岩矿鉴定工作对推动矿床学发展意义重大,应加强宏观鉴定与微观鉴定的综合研究工作,为矿床学研究提供更加可靠的证据。Rock ore identification is an important part of ore deposit science and metallogenic law research,which is of great significance to the analysis of ore-bearing hydrothermal evolution process and the establishment of metallogenicmodel.Based on porphyry deposit and skarn deposit,this paper analyzes the application of rock ore identification in sheet and thin section identification.The crystal sequence of different minerals and the different times of the same metal mineral can be obtained by the optical identification.The work of rock and ore appraisal is of great significance to the development of ore deposit science.
