The principal investigator has used a laser microprobe, linked with a highly sensitive mass spectrometer, to do unique chemical analyses on fluid inclusions. He will expand the scope of his studies to include noble gases and halogens in studying fluid inclusions in mineralized porphyry copper deposits and in high- grade metamorphic rocks. He will also investigate nucleogenic noble gas isotopes in unirradiated splits of the same samples. This work will be especially important in the development of new analytical techniques which may eventually be applied to many other geologic studies.

主要研究人员使用激光微探针与高灵敏度质谱仪连接，对流体包裹体进行独特的化学分析。他将扩大研究范围，将惰性气体和卤素纳入研究矿化斑岩铜矿床和高级变质岩中的流体包裹体。他还将研究同一样品的未辐照裂片中的成核稀有气体同位素。这项工作对于开发新的分析技术尤其重要，这些技术最终可能应用于许多其他地质研究。
