Delineation of Canadian sedimentary basins from MAGSAT data

A crustal scalar magnetic anomaly map of Canada and the northern United States is derived using data collected from the MAGSAT satellite. The anomalies are correlated to geological features. Basins associated with failed arms of old rifts have high magnetic anomalies. The Rocky Mountains, the Appalachian Mountains, the suture zone of the Grenville province, modern hotspots and ocean ridges have low magnetic anomalies.
