Energy-Dispersive X-ray Fluorescence Spectrometry: Undergraduate Applications in Geology and Geochemistry

对全岩地球化学分析技术和应用的“动手”理解是学生在地质学本科生准备过程中必不可少的一部分。三一大学地质学系将把能量色散X射线荧光光谱仪系统(ED-XRF)整合到其本科课程中。所有最终的职业生涯可能需要应用地球化学原理的学生都将接触到这种技术的多种用途。该仪器将被用作课程和研究的工具，重点是用于解决包括火成岩、变质岩和沉积岩和矿床的成因在内的地质问题。该计划的开发将通过收购ED-XRF实现，ED-XRF具有对硅酸盐岩石进行定量多元素分析的能力。

A "hands-on" understanding of the techniques and applications of whole-rock geochemical analysis is an essential part of a student's undergraduate preparation in Geology. The Department of Geology at Trinity University will integrate an energy-dispersive x-ray fluorescence spectrometer system (ED-XRF) into its undergraduate curriculum. All students whose eventual careers might require the application of geochemical principles will be exposed to the multiple uses of this technique. The instrument will be used as a tool in courses and research, with an emphasis on its use in solving geologic problems including the origin of igneous, metamorphic, and sedimentary rocks and ore deposits. Development of the program will be achieved through the acquisition of an ED-XRF which has capability to produce quantitative, multi-element analyses of silicate rocks.
