X-ray Fluorescence Spectrometry in Undergraduate Geology Education

x射线荧光光谱仪是本科地质学课程中最先进的分析仪器。在二年级的课程中介绍了工作原理，学生们可以在几个高级实验室中亲身体验设备，包括岩石学、火成岩岩石学、x射线粉末法、地球化学和经济地质学。学生们在这些课程中使用仪器对各种地质材料进行高精度的主要元素和微量元素分析，阐明课程主题并获得使用现代仪器的实践经验。所要求的设备的分析能力在高年级本科生的研究项目中得到了重要的应用。学生获得准确化学数据的能力大大提高了他们实现研究目标、解决重要问题的能力，并为北加州地质知识做出了有意义的贡献。这些本科项目中的许多都发表了论文，并在专业会议上发表了演讲。* * *

9351228 Longshore An X-ray fluorescence spectrometer is being used as a state of the art analytical instrument in the undergraduate geology curriculum. Operating principles are being introduced in sophomore-level classes, and students are having hands on experience with the equipment in several upper-division laboratories, including petrography, igneous petrology, X-ray powder methods, geochemistry, and economic geology. Students are using the apparatus to perform high precision major and trace element analyses on a variety of geological materials in these classes, elucidating course subject matter and gaining practical experience with modern instrumentation. The analytical power of the requested equipment is finding significant applications in senior undergraduate research projects. The ability of the students to obtain accurate chemical data is greatly enhancing their abilities to achieve their research objectives, to solve important problems, and to contribute meaningfully to the knowledge of northern California geology. Many of these undergraduate projects are leading to publications and presentations at professional meetings. ***
