	Abstract	A dataset consisting of over 300 reflection seismic lines, 75 wells, and numerous
	surface maps was used to develop a set of subsurface maps which are presented here in PDF
	and GIS digital formats.  Map contours are in units of reflection time (msec) or metres and
	depths are relative to a datum of 305 m (1000’) asl.  The area of study extends from 63 to
	66 north latitude and from Great Bear Lake in the east to the Mackenzie Mountains in the
	west and contains the physiographic areas of Great Bear Plain, Mackenzie Plain, and the
	Franklin Mountains including the McConnell and St. Charles ranges.  The maps all show
	relatively thin and undeformed Phanerozoic strata under Great Bear Plain that dip westward
	towards the Laramide deformed belts.  Deepest (or thickest) strata are associated either
	with foreland basins or a central area of subsidence involving rhomboid shaped grabens.
	Prominent tectonic features include the Cambrian Mackenzie Trough and Mahony Arch and
	the multi-phase Keele Arch.  Overprinting these are features created by movement of
	Cambrian salt and by regional tectonics imposed during the Laramide Orogeny.
	Purpose:	Provided as a contribution to the Mackenzie Atlas and regional Petroleum
	Assessmant projects.
	Supplemental Information	In English
