Nov 11, 2014 · In the Superior Province, compelling evidence for plate tectonic processes is provided by the structural features and geochemical composition of accreted terranes [Percival et al., 2012]. At almost the same time, the rate of continental growth decreased significantly.

Jan 1, 2012 · Several late-tectonic events recognized across the Superior Province characterize the cratonization process between 2680 and 2600 Ma. Deposition of “Timiskaming-type” conglomerates, alkaline ...
Jul 1, 2006 · The Winnipeg River terrane was reworked in 2.75–2.68 Ga magmatic and tectonic events, including the central Superior orogeny (2.71–2.70 Ga) that marks accretion of the juvenile western Wabigoon terrane.

[5] The Superior Province, the largest Archean province in the world, has been stable for 2.6 Ga and is underlain by high-velocity upper mantle imaged by several continen-
Jan 1, 2012 · The Canadian Superior Province has become one of the key test pieces to discuss tectonic processes and mechanisms of crustal growth in the Late Archean.
The Superior Craton is a stable crustal block covering Quebec, Ontario, and southeast Manitoba in Canada, and northern Minnesota in the United States. It is the biggest craton among those formed during the Archean period. [ 1 ] .
