Book excerpt: This paper reports results from magnetotelluric measurements made along an approximately 300-kilometre northwest-southeast trending profile that crossed the major geological structures of central Baffin Island. The main goal of this survey was to determine the sub-surface geometry of major geological boundaries, particularly between Archean Rae Craton rocks and overlying Paleoproterozoic continental-margin units. The paper describes data acquisition methods & problems encountered and presents a preliminary model that describes much of the magnetotelluric response observed along the profile.
