This research aims to solve the mystery of how base and precious metal ore bodies are formed in volcanic rocks. Some of these deposits contain in excess of 100 million tonnes of ore. These are rare but very desirable because they represent the most cost effective means of producing metals such as zinc, copper, lead, silver and gold that are essential to modern society. Canadian examples such as Kidd Creek in Ontario and Brunswick #12 in New Brunswick would completely fill 10 Toronto Rogers Centres. Another aspect of my research is to determine the dispersal patterns of contaminants in sediments resulting from the ore-forming process. These contaminants (various metals, barium and arsenic) may provide vectors towards ores.

该研究旨在解决火山岩中碱金属和贵金属矿体的形成之谜。其中一些矿床含有超过1亿吨的矿石。这些是罕见的，但非常可取的，因为它们代表了生产金属，如锌，铜，铅，银和金，是现代社会必不可少的最具成本效益的手段。加拿大的例子，如安大略的基德溪和新玩法的布伦瑞克12号，将完全填满10个多伦多罗杰斯中心。我研究的另一个方面是确定成矿过程产生的沉积物中污染物的分散模式。这些污染物（各种金属、钡和砷）可能成为矿石的载体。
