Tim McIntyre PhD| DERTS Trainees

Tim Defended his PhD on April 11, 2022.

Tim's research was largely focused on using Re-Os isotopes and platinum group elements in crustal hosted peridotites of West Greenland to understand the evolution of the lithospheric mantle underlying the North Atlantic Craton. Tim measured heat producing elements (K, U, and Th) in mantle xenoliths to place constraints on heat production in the lithospheric mantle to be used in geothermal modelling.  He was also involved in the EARTHBLOOM Project, which focuses on constraining the origin and timing of photosynthesis on Earth through studying the geochemistry and sedimentology of Mesoarchean marine carbonates in Northern Ontario.

Tim went on to work with Anglo American as a Discovery Geochemist.
