High Quality Content by WIKIPEDIA articles! The Rae craton is an Archean craton located in northern Canada north of the Superior craton. The Ungava Peninsula, situated on the northeast portion of the Canadian Shield, is where the Rae Province connects with the Superior Province. The area is composed of Archean rocks (ca. 2.7-2.9 Ga) from the Douglas Harbour Domain (see Superior craton). The Archean rocks are overlain by Paleoproterozoic supracrustal sequences (ca. 1.8-2.1 Ga) and intruded by Paleoproterozoic diabase dykes (ca.2.0-2.2 Ga).
