项目摘要

LONG TERM OBJECTIVE - The overall long term objective of my research is to understand the processes controlling nickel, copper, platinum-group elements (PGE), chrome, vanadium, titanium and phosphorus distribution in igneous systems. The study of these elements is used both in fundamental research; considering such problems as how and when the core formed, the effects of meteorite impacts, the formation and segregation of immiscible liquids from silicate magmas, and in applied research developing models for exploration and exploitation of Ni-Cu-PGE and oxide ore deposits. My work covers both aspects but is concentrated on formation of ore deposits.**SHORT TERM OBJECTIVES. - My short term objectives for this NSERC cycle is to investigate processes that control PGE distribution in Ni-Cu-PGE deposits and in particular whether the semi-metals play a role in controlling PGE distribution.**ORIGINALITY - Although the collection of Ni, Cu and PGE by sulfide liquid is well established the source, the partitioning and role of the semi-metals has not been closely considered. Given that many PGE are found in minerals rich in semi-metals their role in concentrating PGE deserves study. **BENEFITS - Four graduate students and one post-doctoral fellow will be trained in ore deposits studies. The role of semi-metals in these types of ore deposits will be more clearly understood and it may be possible to use this information in exploration work.************************

长期目标-我的研究的总体长期目标是了解控制镍，铜，铂族元素（PGE），Chrome，钒，钛和磷在火成岩系统中分布的过程。对这些元素的研究既用于基础研究，考虑诸如核心如何以及何时形成，陨石撞击的影响，硅酸盐岩浆中不混溶液体的形成和分离等问题，也用于开发Ni-Cu-PGE和氧化物矿床勘探和开发模型的应用研究。我的工作涵盖这两个方面，但集中在矿床的形成。**短期替代品。- 我对NSERC循环的短期目标是研究控制镍-铜-铂族元素矿床中铂族元素分布的过程，特别是半金属是否在控制铂族元素分布中发挥作用。起源-虽然收集镍，铜和铂族元素的硫化物液体是公认的来源，分配和半金属的作用还没有仔细考虑。鉴于许多铂族元素存在于富含半金属的矿物中，它们在富集铂族元素中的作用值得研究。** 好处-四名研究生和一名博士后研究员将接受矿床研究培训。将更清楚地了解半金属在这些类型矿床中的作用，并有可能在勘探工作中使用这一信息。
