The proposed research program is centred on the ongoing development and application of Secondary Ion Mass Spectrometry (SIMS) to the microanalysis of natural materials. The key applications proposed encompass a number of subfields of current interest to the investigator i) Ore Deposits Geochemistry, ii) Paleoceanographic Proxies in Marine Biomineralization, and iii) Stable Isotope Systematics of Subduction-Related Volcanism. The SIMS techniques developed for these programs also have manifold additional applications within the general field of Geosciences. The research approach will emphasize the unique capabilities of SIMS for very fine spatial resolution and precise trace element and stable isotopic microanalysis of solids. The glass and mineral reference materials developed in support of this program will also benefit and promote additional collegial use of the Memorial University SIMS Facility, and other microanalytical facilities in the geosciences community.

拟议的研究计划集中在二次离子质谱法（SIMS）中的持续开发和应用中。拟议的关键应用程序包含许多目前感兴趣的子字段i）矿石沉积物地球化学，ii）海洋生物矿化中的古环摄影代理，以及iii）稳定的俯冲相关火山的同位素系统。为这些程序开发的SIMS技术还在地球科学的一般领域中提供了其他应用。研究方法将强调SIMS的独特功能，以实现非常精细的空间分辨率和精确的痕量元素和稳定的同位素微分析。为支持该计划而开发的玻璃和矿物参考材料还将受益并促进纪念大学模拟人生设施以及地球科学社区中其他微分析设施的额外使用。
