X-ray Fluorescence Spectrometry in Undergraduate Geology Education

9351228 Longshore X射线荧光光谱仪是本科地质学课程中使用的最先进的分析仪器。操作原理将在二年级的课堂上介绍，学生们正在几个高级实验室亲身体验这些设备，包括岩石学、火成岩岩石学、X射线粉末方法、地球化学和经济地质学。学生们将使用该仪器对这些课程中的各种地质材料进行高精度的专业和微量元素分析，阐明课程主题，并获得现代仪器的实践经验。所需设备的分析能力在高年级本科生研究项目中得到了重要应用。学生获得准确化学数据的能力大大增强了他们实现研究目标、解决重要问题以及对北加州地质学知识做出有意义贡献的能力。这些本科生项目中的许多都会导致发表论文和在专业会议上发表演讲。***

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. ***
