Application of Powder X-ray Diffraction in Petrology and Mineralogy
-
摘要: X射线衍射是测定物质结构的主要分析手段，广泛应用于物理学、化学、医药学、金属学、材料学、工程技术学、地质学和矿物学。文章综述了粉晶X射线衍射法在造岩矿物、黏土矿物、岩组学、类质同象和结晶度的测定等领域发挥的重要作用。随着测量技术的发展，粉晶X射线衍射在矿物结晶过程中的研究、矿物表面研究、矿物定量相分析和矿物晶体结构测定方面均有新的应用。Abstract: Powder X-ray diffraction is one of the key analytical methods for measurement of material crystal structure and plays an important role in the studies on physics, chemistry, medicine, metallography, material science, engineering and technology, petrology and mineralogy. In this article several applications of powder X-ray diffraction in petrology and mineralogy, such as studies on rockforming minerals and clay minerals, petrofabrics, isomorphism and crystallinity measurement, were introduced. As the development of measurement technology, the new application expectation in research of mineral crystallization process, mineral surface property, quantity analysis of mineral phases and measurement of crystal structure of minerals were also put forward.
