- Data collected in the northeastern part of the Superior Province have highlighted two large terranes that define the evolution of the Archean crust. The Hudson Bay Terrane, in the south and west, shows evidence of an Eoarchean crust (> 3600 Ma) and includes some of the oldest rocks on Earth.

Geology. The Superior Province is subdivided into 19 subprovinces, eight of which are observed in Quebec. Four types of subprovinces are recognized: metasedimentary, metamorphic, volcano-plutonic and plutonic. In Quebec, the Superior Province can be divided into two major zones.

The Superior Province can be divided into three parts. The first part is the northwestern region characterized by high-grade gneiss, such as Minto and Pikwitonei. [8] [14] The second part is the northeastern region, which is characterized by pervasive metamorphic rocks of granulite-facies. [8]
Jan 1, 2012 · The northeastern Superior Province (Figs. 2, 3, 6) is cur- rently considered to comprise two basement terranes, the 3.1–3.9 Ga Hudson Bay terrane and 2.9–2.8 Ga Rivière
1:2 000 000 Scale Geological Compilation of the Superior Craton Legend The Superior Craton is the world's largest Archean craton and has been the subject of geologic research for over 100 years. The craton is comprised of amalgamated fault bounded, lithotectonic subprovinces that trend northeast to southwest.

The northeastern Superior Province east of Hudson and James bays is dominated by 2.78 to 2.69 Ga plutonic rocks emplaced into older crust (3.8-2.83 Ga). Recent discoveries highlight potential...
Jan 1, 2012 · Here we investigate the northeastern part of North America which comprises the Superior Craton, the largest Archean craton in the world, and surrounding Proterozoic belts.
Jan 1, 2011 · The geometric, kinematic, and deformational features along the subprovince boundaries of the Archean Superior Province are keys to understanding the tectonic amalgamation of the province. This field trip investigates the structural geology along two of the subprovince boundaries—the Wabigoon-Quetico and Quetico-Vermilion—of the Superior Craton.
