AbstractThe basement to the Athabasca Basin comprises rocks of the Rae and Hearne provinces and the Taltson magmatic zone. The Rae Province is characterized by mainly metasedimentary supracrustal sequences, including the Murmac Bay Group, and Archean and Proterozoic granitoid rocks. The Hearne Province contains Archean granitoid gneiss with interleaved supracrustal belts including the Archean Ennadai Group, the Paleoproterozoic Hurwitz Group, and other rocks of unknown age. The eastern Hearne Province is dominated by Wollaston Supergroup metasedimentary rocks. The Taltson magmatic zone contains a basement complex that was intruded by ca. 1.99 - 1.96 Ga continental magmatic arc granitoid rocks and 1.95 - 1.92 Ga peraluminous granitoid rocks.

Numerous structural features affected the Athabasca Group and its basement rocks. Their histories were generally protracted and included multiple displacements under ductile and brittle conditions. Mackenzie diabase dykes cut the Athabasca Group, providing its minimum age. The Carswell Structure is thought to be the result of an Ordovician meteorite impact.
