日本东京大学地质学教研室的饭岛东等人与日制产业等厂家协作,试制了一种新的阴极射线发光显微镜。它在岩石结晶表面上照射加速的电子射线时,射入电子能量的大部分因透射及反射而散失;另有一部分成为二次电子、X射线、可见光。由于照射电子射线而发生的可见光,一般称为阴极射线发光(简称CL)。即便是相同的矿石,由于产状及成因不同,就出现颜色(波长)不同的CL。欧美各国把CL观察应用于砂岩的母岩分布区问题及胶结过程的研究。 CL装置TCL-1型的优点:(1)可以同时进行偏光显微镜像和CL像的观察及照像、CL的
Iijima East, Department of Geology, University of Tokyo, Japan, collaborated with manufacturers such as the Japanese industry to try out a new cathode ray luminescence microscope. When it irradiates the accelerated electron beam on the crystalline surface of rock, most of the incident electron energy is lost due to transmission and reflection, while others become secondary electrons, X-rays and visible light. Visible light due to irradiation with electron rays is generally referred to as cathode ray emission (CL). Even if the same ore, because of the origin and causes different, appear color (wavelength) different CL. The European and American countries apply CL observation to the distribution of mother rock and the cementation process of sandstone. CL device TCL-1 type of advantages: (1) can be polarized microscope and CL image observation and photography, CL
