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

1039797 Selleck这项重大研究仪器（MRI）计划拨款支持科尔盖特大学地质系购买综合能量色散X射线（EDS），电子背散射衍射（EBSD）和全色阴极发光（CL）成像系统。 集成包将与高露洁在先前NSF/MRI支持下获得的现有JEOL 6360 LV扫描电子显微镜（SEM）（SEM-0320639）匹配。 SEM的增强功能将支持PI和学生的研究，包括使用EBSD推断其形成的运动学和温度，阿巴拉契亚盆地下古生代石英砂岩的CL-SEM分析，推断微米级水泥织物的成岩历史，以及藤壶外骨骼生物矿化的研究。 科尔盖特大学是一所非博士学位的大学。授予机构。 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，并将其应用于结构地质学和沉积、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.***
