石英是自然界三大类岩石(岩浆岩、沉积岩和变质岩)和地壳中广泛分布的一种矿物,由于其具广泛分布性和化学稳定性,可以用于示踪地质历史并解释地质过程,因此近些年来引起了地质学家和矿物学家们的关注。本文结合实际科研就沉积岩、变质岩、岩浆岩以及一些热液矿床中石英的微量元素分布情况、石英在CL探测器耦合扫描电子显微镜(SEM-CL)和光学显微镜(OM-CL)下的颜色、发光强度及构造形貌特征等进行了探讨,并对石英中微量元素与CL颜色、发光强度及构造之间的关系进行了阐述,以此来提供研究石英的一个基础,最后简单论述了如何应用石英的CL特征来示踪或鉴定不同成因的含石英的岩石。
Quartz is a widely distributed mineral in three major types of rocks (magmatic rocks, sedimentary rocks and metamorphic rocks) and crust in nature. Due to its wide distribution and chemical stability, quartz can be used to trace geological history and explain geological processes In recent years has attracted the attention of geologists and mineralologists. Based on the actual research, the distribution of trace elements in quartz in sedimentary rocks, metamorphic rocks, magmatic rocks and some hydrothermal deposits, the color of quartz under CL-SEM and OM-CL , Luminescence intensity and tectonic features of the quartz were discussed, and the relationship between the trace elements in the quartz and CL color, luminescence intensity and structure was described in order to provide a basis for the study of quartz, and finally briefly discussed how CL characteristics of quartz are used to trace or identify quartz rocks of different origins.
