Studies of plutonic rocks in Archean terranes such as the southern Abitibi subprovince have been an important component in the development of an accretionary tectonic model for the Superior province. In the southern Abitibi subprovince, pretectonic (

Published U–Pb geochronological, geological, and petrochemical data suggest that there are late Archean ensialic greenstone belts (GB) (Michipicoten GB and possibly the northern Abitibi GB), ensimatic greenstone belts (southern Abitibi GB and Batch

MORE than half of the continental crust was formed before about 2,500 million years ago1, yet there is still considerable uncertainty regarding the structure and evolution of the ancient Archaean cratons2–7. Modern analogues proposed for the settin

Lithoprobe seismic-reflection profiles from the 2.75-2.68 Ga southern Abitibi greenstone belt reveal subhorizontal reflection zones of regional extent in the upper 15 km of crust that contrast with the steep dips of rock units and structures at the s

Mafic rocks at Lake Nipigon provide a record of rift-related continental basaltic magmatism during the Keweenawan event at 1109 Ma. The mafic rocks consist of an early, volumetrically minor suite of picritic intrusions varying in composition from oli

The Lac des Iles Complex is a late Archean, mafic to ultramafic complex that is host to 20.4 × 106 t Pt, Pd, and Au mineralization with an average grade of 6.34 g/t platinum-group elements (PGE). The 30 km2 complex, located in the Wabigoon Subprovin

Conformable domes can result from diapirism as well as cross buckling and other types of cross folding. The total-strain pattern of natural structures offers a means of discriminating between diapiric domes and nondiapiric domes. Similarly, one may d
