Abstract The Superior Province consists of northern and southern high-grade gneiss
subprovinces and a central region of alternating granite-greenstone and metasedimentary …

Granitoid magmas are emplaced at the upper crust under a complex interaction of
gravitational processes and horizontal tectonics. Natural intrusive bodies show a wide …

ABSTRACT Views of the Superior Province as an accretionary orogen have developed over
the past two decades as a result of recognition of numerous distinct protocontinental and …

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 …

Abstract Evidence from the Superior Province of the Canadian Shield suggests the
existence of several distinct lithostratigraphic associations in greenstone belts:(1) quartz …

Opinion is still divided whether Precambrian crustal evolution followed uniformitarian
principles and is thus compatible with contemporary plate tectonics, or whether global …

Field observations, and an analysis of the strain field, have been carried out in Archaean
terranes of the Hebei province in the Dharwar craton of India, the Sino-Korean craton in …

Abstract The Superior Province was assembled from continental fragments and intervening
tracts of oceanic crust between 2.72 and 2.68 Ga. Continental blocks (Northern Superior …

The process that generated the continental crust has long been debated. One school argues
that, through most of geological time, the crust formed at convergent margins like most …

The Archaean Minto Block, northeastern Superior Province, is dominated by tonalite–
trondhjemite, enderbite (pyroxene tonalite), granodiorite and granite, with subordinate mafic …
