Airborne Geomagnetic Investigations at the Haughton Impact Structure, Devon Island, Nunavut, Canada: New Results

The well-preserved 23-Ma Haughton impact structure has an original rim diameter estimated at about 24 km. This work extends and completes the survey begun in 1999 to characterize the geomagnetic signature of Haughton. Mapping extent was about 75 W 60 km in order to clearly delineate regional features. Additional information is contained in the original extended abstract.
