AbstractThe Husky Formation is a shale unit with minor sandstone interbeds, and subcrops in the Mackenzie Delta and Tuktoyaktuk Peninsula areas. The fine grained sediments generally occur in coarsening-upward cycles. Within these cycles, three lithofacies are identified: a weakly bioturbated shale facies, a strongly bioturbated mixed shale-sandstone fades, and a weakly bioturbated sandstone fades. The three lithofacies probably represent a mud interbar or shoal fades, a bar or shoal margin fades, and a bar or shoal fades respectively. The environment of deposition was a shallow, siliciclastic, marine shelf, which had a northeast-southwest trend and which deepened to the north or northwest. The fine grained sandstone fades has a complex diagenetic history that includes cementing by silica overgrowths, etching of grains, partial filling of pore space with carbonate cement, and precipitation of a number of clay types as grain coatings and pore fillings between grain boundaries. Porosity is very poor and the reservoir potential of the sandstones is considered to be low.
