TL;DR: In this paper, five discrete accretionary events assembled fragments of continental and oceanic crust into a coherent Superior craton by 2.60 Ga. They exhibit similar sequences of events at 10 million year intervals: cessation of arc magmatism, early deformation, synorogenic sedimentation, bulk shortening, regional metamorphism, late transpression, orogenic gold localization, emplacement of crust derived granites, and postorogenic cooling.

TL;DR: In the central Superior province of the Canadian Shield, a 120 km-wide transition from the low-grade Michipicoten greenstone belt to the high-grade Kapuskasing structural zone represents an oblique section through some 20 km of Archean crust, uplifted along a northwest-dipping thrust fault as discussed by the authors.

TL;DR: The Kapuskasing uplift has been the subject of intense geological and geophysical investigation as Lithoprobe's window on the deep-crustal structure of the Archean Superior Province as discussed by the authors.

TL;DR: In this paper, the authors investigated the relationship between heat flow-heat production and modal abundances of accessory minerals, and found that the relatively large variation in heat production found among the silicic plutonic rocks correlated with modal abundance of accessory mineral.

TL;DR: In the first collaborative study of paleomagnetism and precise U-Pb geochronology in the Minto block of the Superior Province, mafic dyke swarms with three widely divergent paleomagnetic signatures were found.
