Acquisition of a Microscope Facility for Transmitted and Reflected Light Studies of Gas-filled Inclusions in BasalticOlivines and Pyroxenes

9405805 Craig该奖项提供了所需资金的75%，用于购买用于透射和反射光的显微镜系统，用于稀有气体同位素实验室，圣地亚哥加利福尼亚大学斯克里普斯海洋学研究所。大学承诺提供收购所需的剩余资金。该显微镜系统主要用于研究从地幔中挤压出来的玄武岩样品中捕获的流体、玻璃和晶体内含物的研究人员。在提取稀有气体（氩、氦和钕）进行同位素分析之前，需要显微镜来定位和识别这些小包裹体。斯克里普斯海洋研究所的研究人员正在利用地幔中稀有气体的同位素含量来了解地幔的地球化学演化。＊＊＊

9405805 Craig This award provides 75% of the funds required for the acquisition of a microscope system for use with transmitted and reflected light to be used in the rare gas isotope laboratory, Scripps Institution of Oceanography at the University of California, San Diego. The University is committed to providing the remaining funds necessary for the acquisition. The microscope system is mainly to be used by researchers working with fluid, glass, and crystalline inclusions trapped in samples of basaltic rocks that have been extruded from the Earth's mantle. The microscope is needed for the location and identification of these small inclusions prior to extraction of the rare gases (argon, helium, and neodymium) for isotopic analysis. The researchers at the Scripps Institution of Oceanography are using the isotopic content of the rare gases brought up from the mantle to understand the geochemical evolution of the mantle. ***
