This award will provide one-half the funding needed for the acquisition of a high sensitivity noble gas mass spectrometer to be installed and operated in the Geophysical Institute at the University of Alaska-Fairbanks. The University is committed to providing the remaining funds necessary. The mass spectrometer will be used primarily in the application of the argon-40/argon-39 isotopic method of dating rocks and minerals in a variety of research projects including the timing of ore-mineralization, dating of Alaskan Quaternary volcanic sequences, the study of very old continental crust evolution, and the study of the retention of argon in minerals.

该合同将提供购买高灵敏度惰性气体质谱仪所需资金的一半，该质谱仪将在阿拉斯加-费尔班克斯大学的地球物理研究所安装和运行。大学承诺提供剩余的必要资金。质谱仪将主要用于在各种研究项目中应用氩-40/氩-39同位素法测定岩石和矿物的年代，包括矿化时间、阿拉斯加第四纪火山序列的年代测定、非常古老的大陆地壳演化研究以及矿物中氩的保留研究。
