Technician Suppport for the MIT Electron Microprobe Facility

9711826格罗夫这笔赠款提供150,000美元作为三年部分工资支持，用于一名技术人员监督操作和维护，培训新用户，并使用麻省理工学院即将升级的(EAR-9616827)电子显微探头开发分析程序。这是IF/EAR计划下的第一阶段技术支持请求。麻省理工学院和伍兹霍尔海洋研究所的大量教员(通过他们在麻省理工学院/世界卫生组织海洋学联合项目中的关系)和该区域内的大量教员将受益于该设施的能力。目前已资助和计划中的研究将利用新升级的微型探头，包括确定水对俯冲带部分熔融的影响、南部喀斯喀特火山岩的岩石学研究以及样品的高分辨率结构和矿物学分类，以确定随后对同位素成分进行二次离子微探头分析的最佳位置。***

9711826 Grove This grant provides $150,000 as three years partial salary support for a technician to oversee operation and maintenance, train new users and develop analytical routines using the soon-to- be upgraded (EAR-9616827) electron microprobes at the Massachusetts Institute of Technology. This is a Phase I request for technical support under the IF/EAR program. A large number of faculty at MIT and Woods Hole Oceanographic Institution (through their relationship in the MIT/WHOI joint program in oceanography) and within the region will benefit from the capabilities of this facility. Currently funded and planned studies that will take advantage of the newly upgraded microprobes include determination of the influence of water on partial melting in subduction zones, petrologic studies of volcanics in the southern Cascades, and high-resolution textural and mineralogic classification of samples in order to identify prime locations for subsequent secondary ion microprobe analysis of isotopic composition. ***
