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.

主要研究者使用了与高度敏感的质谱仪相关的激光微探针，对流体夹杂物进行独特的化学分析。他将扩大研究范围，以包括矿化斑岩铜沉积物和高级变质岩石中的流体夹杂物，包括贵重气体和卤素。他还将研究相同样品的未辐照分裂中的核基因贵族同位素。这项工作在开发新的分析技术方面尤其重要，最终可能应用于许多其他地质研究。
