Economic Geology

I’ve recently started working on the paleomagnetism and petrology of mineral deposits. Using the magnetic techniques that I have developed, there is enormous potential to advance our understanding of metallogenic processes in a variety of systems.

Co-Ni, Northern Ontario

Cobalt has emerged as one of the most important metals for the production of batteries and other technology needed to transition away from fossil fuels. This project focuses on the complex thermal history of the Cobalt mining district in northern Ontario, and its associated Ag-Ni-Co-As-Bi deposits. The magnetic geothermometer that I have developed is very well suited to understanding the complex thermal history of this area. Results from this unique study will help us to improve the genetic model of the five-element assemblage and aid in ongoing exploration efforts.

Active Metallogenesis

Most metal deposits are fossilized – they are no longer forming new minerals of economic interest. However, we know that new deposits are currently forming in the subsurface in some geologic settings. The magnetic monitoring technique that I have developed can allow us to observe metallogenic processes (magmatic or hydrothermal) as they occur in real-time. Such observations could help us create better genetic models of fossilized deposits. I am currently investigating which systems could benefit from such a monitoring network, and hope to implement this novel technique in the near future.
