This project will fund the acquisition of an Inductively Coupled Plasma - Optical Emission Spectrometer (ICP-OES) for the Miami University Department of Geology. The new instrument will support and enhance existing strengths of the department. Over the past 15 years the Department of Geology has moved to further enhance geochemistry as a prime focus of its research and teaching efforts, and because of this, the need for routine acquisition of reliable, high quality geochemical data continues to grow. The new ICP-OES will become the centerpiece for routine analytical geochemistry teaching and research where precise quantitative analysis of major, minor, and trace elements in a variety of matrices including rocks, minerals, soils, and natural waters is required. Eight geology faculty/staff PIs and associated student research groups and their collaborators initially will utilize the ICP-OES to address hypotheses and elucidate problems in igneous petrogenesis including mantle-crust interactions and evolution, tephrochronology and the environmental context for human evolution, pedogenesis in hyperarid climates and implications for climate change, geomicrobial processes in extreme geological environments, microbe-water-mineral interactions, remediation of heavy metal pollution in groundwater and acid mine drainage, and crystal chemical investigations applied to nuclear waste storage. The new ICP-OES and associated geochemical laboratories will serve to train undergraduate and graduate students and post-doctoral researchers in modern aspects of geological and environmental sample preparation, experimental design, and the use of analytical laboratory equipment. Additionally, women comprised over 50% of our geochemistry research that involved students. Moreover, PIs Hart and Widom currently oversee a combined research group that includes six female graduate and two female undergraduate students, and one African-American student.

该项目将为迈阿密大学地质系购买一台电感耦合等离子体发射光谱仪 (ICP-OES) 提供资金。新工具将支持和增强该部门的现有优势。 在过去的 15 年里，地质系已将进一步加强地球化学作为其研究和教学工作的主要重点，正因为如此，对常规获取可靠、高质量地球化学数据的需求不断增长。新型 ICP-OES 将成为常规分析地球化学教学和研究的核心，其中需要对岩石、矿物、土壤和天然水域等各种基质中的主量、微量和痕量元素进行精确定量分析。 八名地质学教师/工作人员 PI 和相关学生研究小组及其合作者最初将利用 ICP-OES 来解决假设并阐明火成岩成因中的问题，包括地幔-地壳相互作用和演化、岩石年代学和人类进化的环境背景、极度干旱气候中的成土作用和对气候变化的影响、极端地质环境中的地球微生物过程、 微生物-水-矿物质相互作用、地下水和酸性矿山排水中重金属污染的修复以及应用于核废料储存的晶体化学研究。新的ICP-OES和相关的地球化学实验室将在地质和环境样品制备、实验设计以及分析实验室设备的使用等现代方面对本科生、研究生和博士后研究人员进行培训。此外，在我们涉及学生的地球化学研究中，女性比例超过 50%。此外，PI Hart 和 Widom 目前负责管理一个联合研究小组，其中包括六名女研究生、两名女本科生以及一名非裔美国学生。
