Acquisition of Cathodoluminescence, Spectrophotometry, and Microsampling Capabilities for the Study of Large-Scale Ore Forming Systems

9317213 Oreskes该合同为购买阴极发光(CL)显微镜系统提供部分资金，该系统将在达特茅斯学院地球科学系安装和运行。该机构承诺提供购买设备所需的剩余资金。在显微镜下观察矿物时，CL技术可以非常灵敏地检测到晶体生长的多个阶段(在电子轰击下，各种类型和浓度的杂质和其他缺陷会导致特征发光)。达特茅斯大学的研究人员将使用CL设备，他们将应用这项技术来识别矿石矿物的生长阶段，并解释导致矿石形成的地球化学过程。***

9317213 Oreskes This award provides partial funding for the acquisition of a cathodoluminescence (CL) microscope system to be installed and operated in the Department of Earth Sciences at Dartmouth College. The institution is committed to providing the remaining funds needed for the purchase of the equipment. The CL technique allows very sensitive detection of multiple phases of crystal growth when viewing minerals under the microscope (various types and concentrations of impurities and other defects cause characteristic luminescence under electron bombardment). The CL equipment will be used by researchers at Dartmouth who will apply the technique to identify growth phases of ore minerals and interpret the geochemical processes leading to ore formation. ***
