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 - 我研究的总体长期目标是了解控制火成体系中镍、铜、铂族元素 (PGE)、铬、钒、钛和磷分布的过程。对这些元素的研究既可用于基础研究，也可用于基础研究。考虑诸如核心如何和何时形成、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，以及在应用研究中开发镍-铜-铂族元素和氧化物矿床勘探和开采的模型。我的工作涵盖两个方面，但主要集中在矿床的形成上。短期目标。 - 我此 NSERC 周期的短期目标是研究控制 Ni-Cu-PGE 矿床中 PGE 分布的过程，特别是半金属是否在控制 PGE 分布中发挥作用。原创性——虽然通过硫化物液体收集镍、铜和铂族元素的来源已被确定，但半金属的分配和作用尚未得到仔细考虑。鉴于许多 PGE 存在于富含半金属的矿物中，它们在浓缩 PGE 中的作用值得研究。好处 - 四名研究生和一名博士后将接受矿床研究方面的培训。人们将更清楚地了解半金属在这些类型矿床中的作用，并且可以在勘探工作中使用这些信息。
