Precious metal, Lu-Hf, and Re-Os geochemistry of the metasomatized lithospheric mantle: implications for subcrustal precious metal mobilization and MARID petrogenesis
DownloadFall 2022
The connection between metasomatism - the change in chemical composition of a rock via interaction with a fluid or melt - and the formation of metalliferous ore deposits in the Earth’s crust is well established. Similarly, it is now accepted that the Earth’s lithospheric mantle has experienced...

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...
