The Renard kimberlites (52°48’26N, 72°14’52W: Quebec, Canada) are typical for primary diamond deposits: being located within Archean basement (Superior craton). Pb-Pb isotope data of clinopyroxenes also suggests an Archean age (~2.7Ga) for the subcratonic lithospheric mantle (SCLM). The Carolina...

Mantle composition, age and geotherm beneath the Darby kimberlite field, west central Rae Craton
DownloadFall 2018
The Rae Craton, northern Canada, contains several diamondiferous kimberlite fields that have been a focus of episodic diamond exploration. Relatively little is known about the deep mantle lithosphere underpinning the architecturally complex crust. Previous studies in the region have focused on...

The Age and Origin of Lithospheric Mantle Beneath Central Victoria Island and Parry Peninsula, Northern Canada
DownloadSpring 2016
New mineral major and trace element chemistry, bulk rock major element chemistry plus bulk rock and olivine PGE-Re-Os isotope data are presented for kimberlite-borne mantle xenoliths from Central Victoria Island, Nunavut and Parry Peninsula, Northwest Territories. The data, along with new and...
