Cation and Anion Distributions in Minerals

主要研究人员将从实验和理论上研究矿物中的阳离子和阴离子分布，主要使用x射线和中子衍射技术。他们还将编制一个矿物晶体结构测定的大型计算机数据库，然后利用该数据库生成相同矿物的x射线粉末衍射图。这些努力的结果将为许多地球科学家，特别是矿物学家和岩石学家，以及材料科学等其他学科领域的研究人员提供感兴趣的基本数据。

The principal investigators will experimentally and theoretically investigate cation and anion distributions in minerals, primarily using X-ray and neutron diffraction techniques. They also will compile a large computer data base of mineral crystal structure determinations, and in turn use the data base to generate X-ray powder diffraction patterns for the same minerals. The results of these efforts will provide basic data that is of interest to many earth scientists, especially mineralogists and petrologists, as well as to investigators in other disciplinary areas such as materials science.
