摘　　要：岩矿鉴定在矿床勘查中占据着重要地位,推动了矿床学向微观研究的进程,在现代地质工作中应用广泛,通过薄片、光片显微鉴定获取岩(矿)石矿物组成、形态特征,矿物生成序列,结构、构造、岩(矿)石类型,本文以某铜铅锌矿床为例,通过4块矿石分别制作相应光片,在反射光显微镜下鉴定研究,得出矿石金属矿物组成为黄铜矿、方铅矿、闪锌矿、黄铁矿、斑铜矿、黝铜矿,提出黄铁矿早于斑铜矿形成,斑铜矿早于黄铜矿形成,黄铜矿早于闪锌矿形成,闪锌矿早于黝铜矿形成,黝铜矿早于闪锌矿形成,进而为分析矿床成因及后续勘查研究工作提供有价值的参考。Rock and mineral identification plays an important role in deposit exploration and promotes the process of microscopic research of deposit science.It is widely used in modern geological work.Through thin section and light sheet microscopic identification,the mineral composition,morphological characteristics,mineral generation sequence,structure,structure and rock (ore) type of rock (ore) are obtained.This paper takes a copper lead-zinc deposit as an example,Through the corresponding light films made from the four ores and identified and studied under the reflected light microscope,it is concluded that the metal mineral composition of the ore is chalcopyrite,galena,sphalerite,pyrite,bornite and tetrahedrite.It is proposed that pyrite is formed earlier than bornite,bornite is formed earlier than chalcopyrite,chalcopyrite is formed earlier than sphalerite,and sphalerite is formed earlier than tetrahedrite,Tetrahedrite was formed earlier than sphalerite,which provides a valuable reference for analyzing the genesis of the deposit and subsequent exploration and research.
