X-ray Fluorescence Spectrometry in Undergraduate Geology Education

9351228 Longshore X 射线荧光光谱仪在本科地质学课程中被用作最先进的分析仪器。 大二课程中将介绍操作原理，学生们将在几个高年级实验室中亲身体验设备，包括岩相学、火成岩学、X 射线粉末方法、地球化学和经济地质学。 在这些课程中，学生们使用该设备对各种地质材料进行高精度主元素和微量元素分析，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极大地提高了他们实现研究目标、解决重要问题以及为北加州地质学知识做出有意义贡献的能力。 许多本科生项目都在专业会议上发表文章和发表演讲。 ***

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. ***
