X-Ray Powder Diffraction in Geology

X射线衍射长期以来一直是矿物鉴定的标准技术。现代仪器的改进和软件通用性的重大进步扩大了X射线衍射仪(XRD)的潜在用途，包括在各种地质主题中的本科生教学和学生研究。该项目包括获得一份毕业证书，并增加本科生的研究机会。这个项目允许地质部门要求高级研究问题包括分析数据。将现代实验室仪器的数据与理论和实地观测相结合是至关重要的，因为分析仪器已成为当前地球科学实践的基础。X射线衍射学是所有地质学专业必修的矿物学和岩石学课程序列的主要组成部分，其他课程也向本科生介绍了X射线衍射学的基本应用。

X-ray diffraction has long been a standard technique for mineral identification. Improvements in modern instruments and major advances in the versatility of software have expanded the potential uses of X-ray diffractometers (XRDs) to include undergraduate instruction and student research in a variety of geological topics. This project involves acquisition of an XRD and enhancement of research opportunities for undergraduates. This project allows the geology department to require senior research problems to include analytical data. Integration of data from modern laboratory instruments with theory and field observations is essential because analytical instrumentation has become fundamental to the current practice of geoscience. The XRD is a major component of the Mineralogy and Petrology course sequence required of all geology majors, and essential applications of XRD are being introduced to undergraduates in other courses.
