This award will provide 45 per cent of the funds necessary to purchase an automated, wave-length dispersive x-ray fluorescence spectrometer system to be installed in the Hawaii Institute of Geophysics at the University of Hawaii. The remaining funds will be provided by the institution. The new instrument is to replace an antiquated and severely limited instrument which is incapable of meeting the research needs of the geochemistry group at the University of Hawaii. The spectrometer is capable of routine analysis for major and trace elements in a wide range of natural materials. The active research projects which will use the new machine heavily include studies of the Galapagos ocean-spreading center's failure and propagation mechanisms, detailed monitoring of petrochemical changes in eruptions of Kilauea Volcano, and the geochemistry of the very fast spreading segments of the East Pacific Rise.

这笔赠款将提供必要资金的45%， 购买一台自动波长色散X射线荧光仪 光谱仪系统将安装在夏威夷研究所， 夏威夷大学地球物理学。剩余资金将 由机构提供。新仪器将取代 这是一个过时的、有严重局限性的工具， 满足地球化学小组的研究需要， 夏威夷大学。 该光谱仪能够对主要和次要成分进行常规分析， 微量元素在各种天然材料。活性 将大量使用这台新机器的研究项目包括 研究加拉帕戈斯海洋扩张中心的失败， 传播机制，详细监测石化 基拉韦厄火山喷发的变化， 东太平洋海隆快速扩张的部分
