The aim of this research program is to understand how some of the world's largest nickel-copper-platinum deposits in Canada, China, and Russia have formed, in order to aid in the discovery of new deposits. Each project includes detailed mapping of field exposures, logging of diamond drill cores, examinations of the rocks using light optical and electron optical microscopic techniques, analysis of the chemical and isotopic compositions of the ores and the rocks in which they occur, and mathematical models of the geochemical and fluid dynamic processes involved in their formation. The data and interpretations generated in this program will extend our knowledge of the processes involved in generating nickel-copper-platinum deposits, and the geological, genetic, and exploration models generated in the various projects will have broad applications and will aid in their exploration worldwide.

该研究计划的目的是了解加拿大，中国和俄罗斯的一些世界上最大的镍-铜-铂矿床是如何形成的，以帮助发现新的矿床。每个项目都包括详细绘制野外暴露图、记录金刚石钻芯、利用光学和电子光学显微镜技术检查岩石、分析矿石和矿石所在岩石的化学和同位素组成以及矿石形成过程中所涉及的地球化学和流体动力学过程的数学模型。该项目中生成的数据和解释将扩展我们对镍-铜-铂矿床生成过程的了解，各个项目中生成的地质、遗传和勘探模型将具有广泛的应用，并将有助于全球范围内的勘探。
