MRI: Acquistion of Integrated Energy Dispersive X-Ray, Electron Backscatter Diffraction and Panchromatic Cathodoluminescence Imaging System

1039797销售这项重大研究仪器(核磁共振)计划拨款支持为高露洁大学地质学系采购集成的能量色散X射线(EDS)、电子背散射衍射(EBSD)和全色阴极发光(CL)成像系统。该集成包将与高露洁收购的现有JELL6360LV扫描电子显微镜(扫描电子显微镜)相匹配，该扫描电子显微镜具有先前的国家科学基金会/核磁共振支持(EAR-0320639)。扫描电子显微镜的增强能力将支持PI和学生研究，包括使用EBSD对科迪勒核心杂岩中的下盘糜棱岩进行岩石组构研究以推断其形成的运动学和温度，对阿巴拉契亚盆地下古生界石英砂岩进行CL-SEM分析以推断微米级水泥组构的成岩历史，以及藤壶外骨骼的生物矿化研究。高露洁大学是一所非授予博士学位的机构。该仪器将支持本科生在最先进的电子显微镜研究方法方面的培训，并将其应用于构造地质学和沉积、火成岩和变质岩石学。

1039797 SelleckThis Major Research Instrumentation (MRI) Program grant supports acquisition of an integrated energy dispersive X-ray (EDS), electron backscatter diffraction (EBSD) and panchromatic cathodoluminescence (CL) imaging system for the Department of Geology at Colgate University. The integrated package will be mated to an existing JEOL 6360LV scanning electron microscope (SEM) that was acquired by Colgate with previous NSF/MRI support (EAR-0320639). The enhanced capabilities of the SEM will support PI and student research including rock fabric investigations of footwall mylonites from Cordilleran core complexes using EBSD to infer the kinematics and temperature of their formation, CL-SEM analysis of lower Paleozoic quartz sandstones of the Appalachian basin to infer the diagenetic history of micron-scale cement fabrics, and studies of the biomineralization of barnacle exoskeletons. Colgate University is a non-Ph.D. granting institution. The instrumentation will support undergraduate student training in state-of-the-art electron microscopy research methods with applications to structural geology and sedimentary, igneous and metamorphic petrology.***
