Summary(Plain Language Summary, not published)
Mostly situated above latitude 75o North in the central part of the Canadian Arctic Islands, the Bathurst Island archipelago includes Bathurst Island proper and six other significant islands to north and west. The area is known for its former oil production from the Bent Horn oil field (1985-1996) and mining of the Polaris zinc deposit on nearby Little Cornwallis Island (1981-2002). Named structures of Cornwallis Fold belt feature evidence of unroofing during deposition of Bathurst Island and Stuart Bay beds and Prince Alfred Formation. In plan view these are kinematically linked to presumed easterly- and northeasterly-striking wrench faults that are reactivated as thrusts during the development of Parry Islands Fold Belt. Deformation in Parry Islands Fold Belt features upright surface folds, subsurface thrusts, ductile deformation and detachment in Ordovician salt and Devonian shale.
