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.

拟议的研究计划的中心是正在进行的二次离子质谱仪(SIMS)的开发和应用，以用于天然材料的微量分析。建议的主要应用包括：1)矿床地球化学；2)海洋生物矿化的古海洋学指标；3)俯冲相关火山作用的稳定同位素系统学。为这些程序开发的SIMS技术在地球科学的一般领域也有许多额外的应用。研究方法将强调SIMS在非常高的空间分辨率以及对固体进行精确的微量元素和稳定的同位素微量分析方面的独特能力。为支持这一计划而开发的玻璃和矿物标准物质也将有利于和促进纪念大学SIMS设施和地球科学界其他微量分析设施的更多联合使用。
