Proton induced X-ray emission ( PIXE), X-ray diffraction ( XRD), Laser raman spectroscopy ( LRS) and scanning electron microscope ( SEM) are used to study the mineralogy of several lapis lazuli samples from Afghanistan, Baikal of Russia and other places. 利用质子激发X射线荧光(PIXE)、X射线衍射(XRD)、激光拉曼光谱(LRS)以及扫描电镜(SEM)技术对来自阿富汗、俄罗斯贝加尔湖等地的几个青金石样品进行了岩石矿物学特征分析。
