Research Summary
Redox-sensitive metal isotope systems, like uranium, iron and chromium, are valuable tools for shedding light on past environmental conditions. Because these metals change their solubility and behaviours based on the oxidation state of their surroundings, analyzing their isotopic composition in sediments or the ocean helps scientists understand how oxygen levels have varied over time. Dr. Brian Kendall, Canada Research Chair in Redox-Sensitive Metal Isotope Geochemistry, is studying these systems to advance our understanding of natural resource formation and the co-evolution of Earth’s environment and life.
He and his research team are focusing on novel thallium and rhenium isotope systems to gain new insights into the genesis of critical mineral and gold deposits. They are also exploring how these systems can be used to reconstruct the extent of Mesozoic ocean deoxygenation following large volcanic greenhouse gas injections. Their findings will enhance our understanding of the formation of critical mineral and gold deposits and help predict future ocean deoxygenation due to climate change.
