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.***

1039797 Selleck 这项重大研究仪器 (MRI) 计划拨款支持为科尔盖特大学地质系购置集成能量色散 X 射线 (EDS)、电子背散射衍射 (EBSD) 和全色阴极发光 (CL) 成像系统。 该集成包将与现有的 JEOL 6360LV 扫描电子显微镜 (SEM) 配合使用，该显微镜是高露洁在之前的 NSF/MRI 支持下购买的 (EAR-0320639)。 SEM 的增强功能将支持 PI 和学生研究，包括使用 EBSD 对科迪勒拉岩心复合体的下盘糜棱岩进行岩石结构研究，以推断其地层的运动学和温度，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大学。授予机构。 该仪器将支持本科生接受最先进的电子显微镜研究方法的培训，并将其应用于构造地质学和沉积、火成岩和变质岩石学。***
