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

1039797 selleck该主要研究仪器（MRI）计划资助为科尔盖特大学地质系购买集成能量色散x射线（EDS），电子背散射衍射（EBSD）和全色阴极发光（CL）成像系统。该集成封装将与现有的JEOL 6360LV扫描电子显微镜（SEM）相匹配，该扫描电子显微镜是高露洁公司在以前的NSF/MRI支持下获得的（EAR-0320639）。扫描电镜的增强功能将支持PI和学生的研究，包括使用EBSD对科迪勒兰岩心杂岩下盘糜伦岩的岩石组构进行研究，以推断其形成的运动学和温度，对阿巴拉契亚盆地下古生代石英砂岩进行CL-SEM分析，以推断微米尺度水泥组构的成岩历史，以及研究生物矿化的研究。科尔盖特大学是一个非博士。授予机构。该仪器将支持最先进的电子显微镜研究方法的本科生培训，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.***
