Coulson and three co-authors reported in 2001 that the Archean Ennadai-Rankin greenstone belt crops out in northeast Saskatchewan. It hosts mainly supracrustal rocks that extend through the Snowbird Lake area in the Northwest Territories, to Rankin Inlet on Hudson Bay in Nunavut.
The belt is structurally interleaved with continental rocks of the underlying Hearne Province and the whole sequence was subsequently intruded by several granitoid suites. In northeast Saskatchewan, the Ennadai supracrustal sequence comprises dominantly mafic metavolcanic rocks (flows and tuffs), minor intermediate to felsic metavolcanic rocks, hypabyssal intrusives, and subordinate metasedimentary rocks.
All rocks have been affected by regional metamorphism and tectonism.
