An Eocene post-kimberlite maar lake : lacustrine oil-shale crater-fill deposits, Lac de Gras area, Northwest Territories, Canada / A.P. Hamblin.: M183-2/7809E-PDF
"Sedimentology and organic petrology-geochemistry from a 160-metre core have been integrated to study the characteristics of an isolated pocket of fine-grained, siliciclastic Eocene sediments deposited within a small kimberlite crater basin, Lac de Gras, Northwest Territories, Canada. These sediments overlie the “Giraffe Pipe”, a kimberlite occurrence located at about 65°N/110°W, 25 km northeast of the Ekati Diamond Mine. The strata recovered in the studied core represent an overall shallowing-upward succession of lacustrine-peat mire basin-fill, interpreted to portray the deposits of a maar lake, one of the first identified in Canada (and one of the few maars anywhere to be associated with a kimberlitic pipe)"--Abstract, page 1.
