Acquisition of an Automated X-ray Fluorescence Spectrometry System for Geological and Geochemical Research

该合同将提供购买自动波长色散x射线荧光光谱仪系统所需资金的45%，该系统将安装在夏威夷大学的夏威夷地球物理研究所。剩余的资金将由该机构提供。新仪器将取代一种过时的、功能严重受限的仪器，这种仪器不能满足夏威夷大学地球化学小组的研究需要。该光谱仪能够对多种天然物质中的主要元素和微量元素进行常规分析。将大量使用这台新机器的正在进行的研究项目包括研究加拉帕戈斯群岛海洋扩张中心的失效和传播机制，详细监测基拉韦厄火山喷发时的石化变化，以及东太平洋隆起快速扩张部分的地球化学。

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.
