My long-term research program studies mineral deposits to better understand their formation and to develop indicator mineral methodologies useful for exploration by the industry and government agencies. I propose to carry a research program to reach 2 short term objectives: 1) to investigate the triggers of gold precipitation in orogenic gold deposits because this dictates where and how much gold occurs in a system; and 2) to investigate the processes controlling the incorporation of minor and trace elements in magnetite, and the potential impact of the currently undetected nano-inclusions using in situ analytical techniques. The research program will train 2 PhD and 5 BSc students that will gain the skills for successful careers in academia, government of industry. The HQP will use state-of-the-art instruments to measure the chemical and isotopic composition of minerals to inform on the conditions of formation of the mineral deposits. This will provide fundamental knowledge on the triggers that cause precipitation of gold in veins, and on the minuscule nanometric inclusions that carry a component of the chemical signature of minerals used in indicator mineral surveys by government agencies and the mineral exploration industry. The impact will be significant to ensure the continued leadership of Canada in mineral deposit geology, and to provide unique knowledge and methodologies to improve and develop efficient mineral exploration programs. Highly efficient mineral exploration programs are critical to ensure the future well-being of the mineral industry, its world-wide leadership, and to find the mineral resources for the well-being of the Canadian economy.

我的长期研究计划研究矿床，以更好地了解它们的形成，并开发对行业和政府机构勘探有用的指标矿物方法。我建议进行一项研究计划，以达到2个短期目标：1）调查金沉淀在造山金矿床的触发因素，因为这决定了金在系统中的位置和数量; 2）调查控制磁铁矿中微量元素和微量元素掺入的过程，以及使用原位分析技术目前未检测到的纳米包裹体的潜在影响。该研究计划将培养2名博士和5名理科学生，他们将获得在学术界，工业政府成功职业生涯的技能。HQP将使用最先进的仪器来测量矿物的化学和同位素组成，以了解矿床形成的条件。这将提供关于导致矿脉中金沉淀的触发因素的基本知识，以及关于微小的纳米夹杂物的基本知识，这些夹杂物携带政府机构和矿产勘探行业在指示矿物调查中使用的矿物化学特征的一个组成部分。其影响将是重大的，以确保加拿大在矿产存款地质学的持续领导地位，并提供独特的知识和方法，以改善和发展有效的矿产勘探计划。高效的矿产勘探计划对于确保矿产行业的未来福祉、其全球领导地位以及为加拿大经济的福祉寻找矿产资源至关重要。
