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. ***

9351228 Longshore X射线荧光光谱仪被用作本科地质学课程中最先进的分析仪器。 操作原理正在介绍在小学水平的课程，学生们有实践经验的设备在几个高年级的实验室，包括岩相学，火成岩，X射线粉末方法，地球化学和经济地质学。 学生们正在使用该设备进行高精度的主要和微量元素分析的各种地质材料在这些类，阐明课程的主题，并获得与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提高了他们实现研究目标，解决重要问题的能力，并为北方加州地质学知识做出了有意义的贡献。 这些本科项目中的许多都导致专业会议上的出版物和演讲。 ***
