9406305 Hodges This award provides partial funding for the support of a technician assigned to the solid-source and gas-source mass spectrometry laboratories in the Department of Earth, Atmospheric and Planetary Sciences at the Massachusetts Institute of Technology. The laboratories are engaged in ongoing programs of research and graduate education that require full-time technical assistance. Current basic research projects focus on the use of radiometric dating techniques to interpret large-scale tectonic processes and Earth history. *** 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. ***

9406305霍奇斯该奖项为分配到麻省理工学院地球、大气和行星科学系固体源和气源质谱实验室的一名技术人员提供部分资金支持。这些实验室从事正在进行的研究和研究生教育项目，需要全职的技术援助。目前的基础研究项目集中在使用放射性测年技术来解释大规模的构造过程和地球历史。*** 9405805 Craig该奖项提供所需资金的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，加州大学圣地亚哥分校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。＊＊＊
