Acquisition of a High-Sensitivity 40Ar/39Ar Dating System for the University of Alaska Fairbanks

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，该仪器将在阿拉斯加大学费尔班克斯分校的地球物理研究所安装和运行。该大学承诺提供所需的剩余资金。质谱仪将主要用于应用Ar-40/Ar-39同位素方法测定岩石和矿物的年龄，用于各种研究项目，包括成矿时间、阿拉斯加第四纪火山序列的测年、非常古老的陆壳演化研究以及Ar在矿物中的保留研究。

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.
