Multidisciplinary geophysical investigations applied to unconformity–associated uranium exploration, Athabasca Basin, Canadian Shield

The Mesoproterozoic Athabasca Basin provides approximately one-third of world uranium primary production from<br>deposits located at or near the sub-basin unconformity, and because they are buried, geophysics plays a key role in their<br>exploration. This role is examined using results of recent studies near the McArthur River deposit lying at a depth of<br>about 550 m.
