项目摘要
1038684McClellandThis grant supports acquisition of a cathodoluminescence (CL) spectrometer which will be mated to an existing variable pressure scanning electron microscope (SEM) in the Department of Geosciences at the University of Iowa. CL imaging will support studies of mineral growth history by allowing for visualization and mapping of crystal zoning and microstructural characteristics. CL scanning using an SEM will support subsequent targeted elemental analysis and/or isotopic analysis of distinct growth rims using other electron microscopy techniques, secondary ion mass spectrometery or laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). The instrument will complement a recently NSF MRI supported laser ablation ICP-MS facility in the Department of Geoscience for zircon geochronology and trace element zonation in minerals and support a range of research in igneous and metamorphic petrology, impact processes, and analysis of clastic sedimentary and carbonate phases to elucidate the environmental conditions at the time of their deposition. The CL microscope will support student research training across multiple departments on campus and the PIs seek to attract underrepresented students through an extant Alliance for Graduate Education and Professoriate (AGEP) program and a NASA Education grant targeted at encouraging undergraduate women to pursue science careers. The instrument will also support collaborative research with faculty and students from nearby Cornell College, a regional liberal arts institution. ***
1038684 McClelland这笔赠款支持购买阴极发光(CL)光谱仪,该光谱仪将与爱荷华大学地球科学系现有的可变压力扫描电子显微镜(SEM)配对。化学发光成像将支持矿物生长历史的研究,因为它允许可视化和绘制晶体分带和微结构特征。使用扫描电子显微镜的CL扫描将支持随后使用其他电子显微镜技术、二次离子质谱仪或激光烧蚀电感耦合等离子体质谱(LA-ICPMS)对不同的生长圈进行有针对性的元素分析和/或同位素分析。该仪器将补充地球科学系最近由NSF MRI支持的激光消融电感耦合等离子体质谱(ICPMS)设备,用于矿物中的锆石年代学和微量元素分带,并支持一系列火成岩和变质岩石学、冲击过程以及碎屑沉积和碳酸盐相分析的研究,以阐明它们沉积时的环境条件。CL显微镜将支持校园内多个系的学生研究培训,PI寻求通过现有的研究生教育和教授联盟(AGEP)计划和NASA旨在鼓励本科生追求科学职业的教育补助金来吸引代表性不足的学生。该仪器还将支持与附近康奈尔学院(Cornell College)的教职员工和学生进行合作研究。康奈尔学院是一所地区性文科机构。***
