Summary(Plain Language Summary, not published)
A series of 5 magnetic maps at a scale of 1: 2 400 000 are used to define 75 magnetic domains within the Rae craton, Canadian Shield, using patterns and amplitudes of magnetic anomalies to differentiate areas having magnetic characteristics distinct from those of adjacent domains. Magnetic anomalies generally reflect the geology of an area to varying degrees, hence the magnetic domains are essentially a proxy for geological domains. In the Canadian Shield, where glacial superficial cover is widespread and geological mapping may be reconnaissance in nature, definition of such domains provides a new perspective and framework for directing future geological mapping and investigations. The magnetic domains also provide a geophysical perspective on the overall internal structural fabric of the craton that could contribute to studies of the tectonic history of the craton.
