摘要: Abstract This paper reviews key characteristics of kimberlites on the Ekati property, NWT, Canada. To date 150 have been discovered five which are mined for diamonds. The intrude Archean basement central Slave craton. Numerous Proterozoic diabase dykes area. Precambrian rocks overlain by Quaternary glacial sediments. No Phanerozoic present. However, mudstone xenoliths and disaggregated sediment within indicate that late-Cretaceous Tertiary cover (likely
