This project funds the development of an x-ray fluorescence (XRF) spectroscopy laboratory in the Department of Geology. Improvement of the analytical geochemistry laboratory is the next logical step in development of the department's instructional and undergraduate research program. The new equipment consists of a Rigaku RIX-2000 wavelength dispersive sequential XRF spectrometer and associated sample preparation equipment to support complete whole-rock, major-element, and trace-element analysis of the full range of geological samples. The acquisition of this instrumentation allows full implementation of a new geology curriculum that is aimed at improving the undergraduate students preparation for entry both into the work force and graduate school. The new curriculum involves reworking the mineralogy/petrology sequence of courses, significant modernization of the sedimentation and stratigraphy curriculum, updating of courses throughout the program, and the addition of a capstone experience that will include a collaborative research project for the majority of students. The XRF is used directly for instruction in one introductory course, four upper-division courses, and an interdisciplinary course for chemistry majors and significantly enhances opportunities for interdisciplinary teaching and research.

该项目资助在地质系建立一个X射线荧光光谱实验室。 分析地球化学实验室的改进是该部门的教学和本科生研究计划发展的下一个合乎逻辑的步骤。 新设备包括理学RIX-2000波长色散顺序XRF光谱仪和相关的样品制备设备，以支持对全系列地质样品进行完整的全岩、主元素和痕量元素分析。 这种仪器的收购允许全面实施新的地质课程，旨在提高本科生进入劳动力和研究生院的准备。 新课程涉及重新设计矿物学/岩石学课程序列，沉积和地层学课程的显着现代化，整个课程的更新，以及增加一个顶点体验，其中包括为大多数学生提供的合作研究项目。 XRF直接用于一门入门课程，四门高年级课程和化学专业的跨学科课程的教学，并显着提高了跨学科教学和研究的机会。
