Acquisition of a Wavelength-Dispersive, Automated X-Ray Fluorescence (XRF) Spectrometer System

0075405 Misra这笔赠款提供了部分支持的费用，获得波长色散，自动X射线荧光（XRF）光谱仪系统，有能力产生高精度分析的主要，次要和痕量元素的岩石和土壤的散装样品。 该仪器将是我们的教师正在进行的几个NSF资助的研究项目的一个组成部分。 其中包括史蒂文·德里塞和克劳迪娅·莫拉对古生代古土壤的研究，劳伦斯·泰勒对西伯利亚克拉通地幔捕虏体的研究，以及罗伯特·哈彻对阿巴拉契亚山脉南部花岗岩类和相关岩石的研究。 该仪器还将为该部正在进行的其他研究项目提供重要的分析支持，这些项目包括：Kula Misra对阿巴拉契亚南部镁铁质-超镁铁质岩石和与矿床有关的寄主岩石的研究; Steven Driese和Larry McKay对腐泥土中污染物和胶体迁移的调查; Otto Kopp对约旦卡拉克高原的地质材料和陶器的分析;以及西奥多·拉博特卡对高温流体-岩石相互作用的评价。 来自大学其他单位的潜在用户表示需要该仪器提供的分析能力，并将支持其维护，包括植物和土壤科学，人类学，化学和材料科学与工程的教师。

0075405MisraThis grant provides partial support of the costs of acquiring a wavelength-dispersive, automated X-ray fluorescence (XRF) spectrometer system that has the capability of producing high-precision analyses of major, minor, and trace elements in bulk samples of rocks and soils. The instrument will be an integral part of several NSF-funded research projects being conducted by our faculty. These include the studies of Paleozoic paleosols by Steven Driese and Claudia Mora, of mantle xenoliths from the Siberian craton by Lawrence Taylor, and of the southern Appalachian granitoids and associated rocks by Robert Hatcher. The instrument will also provide critical analytical support for other active research projects in the Department -- studies of the southern Appalachian mafic-ultramafic rocks and the host rocks associated with mineral deposits by Kula Misra, investigation of contaminant and colloid transport in saprolites by Steven Driese and Larry McKay, analysis of geologic materials and pottery from the Karak Plateau of Jordan by Otto Kopp, and evaluation of high P-T fluid-rock interactions by Theodore Labotka. Potential users from other units in the University, who have indicated a need for the analytical capabilities offered by this instrument and will support its maintenance, include faculty from Plant and Soil Sciences, Anthropology, Chemistry and Materials Science and Engineering.***
