0001322MoecherThis grant provides partial support for the costs of a software and hardware upgrade for the existing ARL SEMQ electron probe microanalyzer operated by the Department of Geological Sciences at the University of Kentucky. The PI is an Associate Professor who has been the Director of the Probe Lab since 1991. The PI and his graduate students will be the primary users of the instrument, however, other faculty and their students in the Department (Prof. Kieran O'Hara, Prof. Susan Rimmer), on campus (Kwok-Wei Ng, Physics Dept.), and in the surrounding area (Eastern Kentucky University, University of Cincinnati, Miami University of Ohio) will make regular use of the instrument. The upgrade consists of new automation (operating system and computer) and new energy dispersive and backscattered detectors for enhanced micro-imaging capabilities. In particular, the PI's research requires the instrument to have X-ray mapping capabilities of major and trace elements. New software that integrates wavelength and energy dispersive detector signals will provide this capability. Projects that will benefit from the upgrade include: (1) chemical and isotopic variability among minerals in polymetamorphic rocks; (2) petrogenetic and stable isotopic studies of pseudotachylyte (melt rocks generated by frictional fusion in brittle fault zones); (3) petrography of sub-glacial sediments and tills; (4) P-T-t studies of metamorphic rocks from the Appalachian orogen; (5) carbonatite petrogenesis; (6) chemical changes in mylonites; and (7) chemical analysis of high temperature superconducting compounds. The acquisition of the new operating and imaging system will also enhance undergraduate instruction and graduate training that are already active on the existing instrument. ***

0001322 Moecher这笔赠款提供了部分支持，用于肯塔基州大学地质科学系现有ARL SEMQ电子探针显微分析仪的软件和硬件升级费用。 PI是一名副教授，自1991年以来一直担任探针实验室主任。 PI和他的研究生将是仪器的主要用户，然而，其他教师和他们的学生在该部门（教授基兰奥哈拉，教授苏珊里默），在校园（吴国伟，物理系），和周边地区（东肯塔基州大学、辛辛那提大学、迈阿密俄亥俄州大学）将定期使用该仪器。升级包括新的自动化（操作系统和计算机）和新的能量分散和反向散射探测器，以增强显微成像能力。 特别是，PI的研究要求仪器具有主要和微量元素的X射线绘图能力。 集成波长和能量色散探测器信号的新软件将提供这种能力。 从升级中受益的项目包括：（1）多变质岩中矿物的化学和同位素变异性;（2）假玄武玻璃的岩石成因和稳定同位素研究（3）冰下沉积物和冰碛物的岩相学研究，（4）阿巴拉契亚造山带变质岩的P-T-t研究，（5）碳酸盐岩成因，（6）碳酸盐岩的成因，（7）碳酸盐岩的成因，（8）碳酸盐岩的成因，（9）碳酸盐岩的成因，（10）碳酸盐岩的成因，（10）碳酸盐岩的成因。（6）糜棱岩的化学变化;（7）高温超导化合物的化学分析。 新的操作和成像系统的采购也将加强本科生教学和研究生培训，已经在现有的仪器上活跃。 ***
