| 摘 要： | 通过对3个不同程度蜕晶化锆石样品的激光拉曼光谱,阴极荧光图像(CL)和U-Pb年龄特征进行对比分析,笔者发现锆石CL图像和激光拉曼光谱测试对蜕晶化锆石及其U-Pb年龄解释有很好的指示作用,因此强调加强矿物内部结构的研究,建议锆石激光拉曼测试、阴极荧光观察及锆石U-Pb同位素测试相结合分析锆石U-Pb年龄数据.

| Abstract: | Three Metamictized Zircons were investigated by Laser-Raman Spectroscopy analysis,CL images,and U-Pb isotopic methods.It is proved that the Laser-Raman Spectroscopy analysis and the CL images can indicate metamict degrees of the zircons and provide significant constraints on U-Pb age interpretation.Particular attention should be attached to the internal texture study of zircons,especially using Laser-Raman Spectroscopy analysis and CL images,to get better interpretation of U-Pb ages. |
