Spring 2020
Archean cratons are comprised of thick, stable continental lithosphere that has persisted for billions of years owing to their isopycnicity (i.e. near neutral buoyancy) and higher viscosity than the surrounding mantle. These regions host diamonds at depths greater than 150 km due to the...

Age, origin and composition of the Attawapiskat lithospheric mantle and its diamonds (western Superior craton, Canada)
DownloadFall 2013
This study reports results from peridotitic and eclogitic xenoliths and di- amond samples from the Attawapiskat area to understand the processes of craton formation and modification in the Superior lithospheric mantle. These diamondiferous kimberlites also provide an opportunity to study the...

U-Pb geochronology and REE geochemistry of the pulsed Cretaceous magmatism in High Arctic Canada: implications for lithospheric evolution and magma genesis
DownloadFall 2016
Cretaceous magmatism in the Sverdrup Basin of Arctic Canada consists of alkalic and tholeiitic phases that are widely considered to be part of the circum-Arctic High Arctic large igneous province (HALIP). The emplacement of large igneous provinces is commonly attributed to mantle plumes. However,...
