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.

这项研究旨在解开火山岩中贱金属矿体和贵金属矿体是如何形成的谜团。其中一些矿床的矿石储量超过 1 亿吨。这些虽然罕见，但却非常理想，因为它们代表了生产现代社会必不可少的锌、铜、铅、银和金等金属的最具成本效益的方式。加拿大的例子，例如安大略省的 Kidd Creek 和新不伦瑞克省的 Brunswick #12 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扩散模式。这些污染物（各种金属、钡和砷）可能会成为矿石的载体。
