阴极发光显微镜是在普通显微镜技术基础上发展起来用于研究岩石矿物组分特征的一种快速简便的分析手段,在沉积学中应用较为广泛。本文先从阴极发光显微镜原理说起,结合前人工作经验和理论成果,介绍常见矿物石英、长石、方解石、白云石的阴极发光特点,并总结其在川西凹陷须家河组储层中的应用。
Cathode luminescence microscopy is a rapid and simple analytical method developed on the basis of ordinary microscope technology for studying the characteristics of rock mineral components, and is widely used in sedimentology. Starting with the principle of cathodoluminescence microscopy, this paper introduces the characteristics of cathodoluminescence of common mineral quartz, feldspar, calcite and dolomite based on previous work experience and theoretical achievements, and summarizes the characteristics of cathodoluminescence in the Xujiahe Formation reservoir in the western Sichuan depression application.
