Postdoctoral Researchers

Duane Petts

 

2012 Ph.D., Geology, Western University – London, Ontario.
Thesis topic: The age and thermal evolution of the lower crust beneath the western Churchill Province, Canadian Shield, Canada.
Supervisors: Dr. Desmond Moser, Dr. Bill Davis and Dr. Fred Longstaffe

2008 M.Sc., Geology, Western University – London, Ontario.
Thesis topic: The petrology and stable isotope geochemistry of hydrothermally altered volcanic and plutonic rocks from the Mira terrane, Cape Breton Island, Nova Scotia, Canada.
Supervisor: Dr. Fred Longstaffe

My research involves using stable isotope microanalysis to understand the role of fluids in the crust and lithospheric mantle. In my current role, I am examining the origin and evolution of diamond forming fluids using Secondary Ion Mass Spectrometry (SIMS) carbon and nitrogen isotope analysis of diamond. This includes diamonds from the Slave (Diavik and Jericho), Kaapvaal (Cullinan, Finsch and Venetia) and West African (Ghana) cratons. Most of this research utilizes the stable isotope microanalytical capabilities of the CAMECA IMS1280 ion microprobe, in the Canadian Centre for Isotopic Microanalysis.

I am also interested in researching the formation and tectonic evolution of the continental crust, and in particular, unraveling the complex formation histories of Archean and Proterozoic crustal rocks. My past research in this area involves understanding the role of fluids during regional-scale melt generation and tectonic-related crustal recycling.
