An XRF Laboratory to Enhance Undergraduate Teaching and Research

点击翻译按钮获取中文摘要

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.
