Acquisition of Optical Spectrometer for Study of Quartz Cathodoluminescence

该奖项提供购买所需资金的一半 阴极发光（CL）光谱仪系统， 位于圣劳伦斯地质系 大学大学致力于提供 剩余资金。 矿物的阴极射线发光特性（ 当受到电子轰击时发出可见光）取决于 各种因素，如晶体缺陷和化学 杂质对于矿物石英，发现其CL 光谱可用于指纹石英颗粒从不同 烃源岩因此， 沉积岩有希望作为重建 古沉积盆地沉积物的物源。的 PI将使用此奖励购买的设备， 进一步研究CL在此类研究中的适用性。

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.
