This award provides one-half the funds required to purchase a cathodoluminescence (CL) spectrometer system that will be housed and operated in the Department of Geology at St. Lawrence University. The University is committed to providing the remaining funds. The cathodoluminescent properties of minerals (the ability to emit visible light when bombarded with electrons) depends on a variety of factors such a crystalline defects and chemical impurities. For the mineral quartz, it is found that its CL spectra can be used to fingerprint quartz grains from different source rocks. Hence, the CL spectra of quartz grains in sedimentary rocks holds promise as a tool for reconstructing the provenance of sediments in ancient sedimentary basins. The equipment purchased with this award will be used by the PI to further investigate the applicability of CL in such studies.

该奖项提供了购买阴极发光（CL）光谱仪系统所需资金的一半，该系统将在圣劳伦斯大学地质系安装和运行。大学承诺提供剩余的资金。矿物的阴极发光特性（受到电子轰击时发出可见光的能力）取决于多种因素，如晶体缺陷和化学杂质。对于矿物石英，发现其CL谱可用于不同烃源岩的石英颗粒指纹。因此，沉积岩中石英颗粒的CL谱有望作为重建古沉积盆地沉积物物源的工具。该项目购买的设备将被PI用于进一步研究CL在此类研究中的适用性。
