The Quandary of the Sask Craton: Origin and Evolution of the Lithospheric Mantle beneath the Sask Craton
DownloadFall 2018
Mantle xenoliths from the Cretaceous (~106 to ~95 Ma) kimberlites at Fort à la Corne (FALC) present a unique opportunity to study the lithospheric mantle beneath the newly recognised Sask Craton. The Sask Craton, a small terrane with Archean (3.2 - 2.5 Ga) crustal ages, is enclosed in the...
