The Lac de Gras kimberlite field is a group of Late CretaceoustoEocene age diatremes in the Northwest Territories, Canada.[1]
The Eocene (ca. 55-50 Ma) age diatremes of the Lac de Gras kimberlite field support two world-class diamond mines called Ekati and Diavik.[2] Ekati, Canada's first diamond mine,[3] has produced 40,000,000 carats (8,000 kg) of diamonds out of six open pits between 1998 and 2008,[3] while Diavik to the southeast has produced 35,400,000 carats (7,080 kg) of diamonds since its foundation in 2003.[4]
