The boundary between the Superior and Churchill provinces of the Canadian Shield is rather well established in the exposed region of northern Manitoba. It is of considerable interest to determine its southern extension which lies buried under the Cretaceous and Paleozoic sediments, in order to better. The Canadian Shield First Nations had indirect contact with Europeans through middlemen traders of the St. Lawrence and Atlantic Gulf regions. Groups in the Canadian Shield, such as the Algonquians, played a crucial role in the fur trade economy once European traders had established posts in the Hudson Bay region.. Mittens from the Montagnais Nation.
The Sunrise property is situated in tbe southern portion of the Wabigoon Subprovlnce of the Superior Province of the Canadian Shield. The claims are approximately kilometers north of tbe Quetico Fault and are bounded to the north by the Turtle Lake Fault. . North America - North America - The Canadian Shield: The Canadian Shield is the principal area of North America where rocks of Precambrian age (i.e., those that are more than million years old) are exposed at the surface. The shield was rifted apart between Canada and Greenland by seafloor spreading in the Labrador Sea and in Baffin Bay between 90 and 40 million years ago.
The Superior Upland Physiographic Province in the Voyageurs area is divided into two subprovinces: the Quetico subprovince and the Wabigoon subprovince separated by the Rainy Lake- Seine River fault zone. The park is mostly in the Quetico subprovince which is composed primarily of biotite schists and granitic rocks with only rare evidence of. In late Archean time ( Ga), repeated episodes of continental collision and north-south directed compression and subduction generated the Algoman (or Kenoran in Canada) Orogeny. During this orogeny, the Superior Craton collided with the Minnesota River Valley terrane, forming part of the Canadian Shield.

The Quetico fault is a major transcurrent fault in the southern Superior Province of the Canadian Shield. Along part of its length the fault forms the boundary between the Quetico and Wabigoon subprovinces.
Dextral motion on the fault is indicated by dextral microfaults and approximately asymmetrical quartz c-axis petrofabrics. The km-long Quetico subprovince consists of monotonous metagraywacke, with derived migmatite and granite, in thrust and/or transcurrent fault contact with the adjacent Wabigoon and Wawa metavolcanic by: The Superior Province consists of northern and southern high-grade gneiss subprovinces and a central region of alternating granite-greenstone and metasedimentary belts.
Subprovinces are commonly fault-bounded and display contrasting lithological assemblages, metamorphic and structural styles, geophysical characteristics, and ages; they are Cited by: The Superior Province is the core of the Canadian Shield and North America.
Being the largest archean terrestrial craton, it covers an area of approximately 1 km 2 of which more than km 2 are in Quebec (Hocq, ). Its north, west and southeast boundaries (Transhudsonian and Grenvillian orogens) are mainly tectonic, while in the south (Penokean Orogen) and north-east.
Abstract Structural analysis in the northern margin of the Quetico subprovince (part of the Archean Superior Province of the Canadian Shield) in Minnesota reveals that the main deformation involved polyphase folding (F 1 recumbent and nappe-like, and F 2Cited by: Tectonic map of North America, showing location of the Archean Superior Province at the core of the Canadian Shield (after Hoffman, ).
Unlabelled white areas are knowledge gaps due to lack of. Quetico is near the southern edge of the Canadian Shield, an exposed km expanse of ancient Precambrian rock, some of which is among the oldest exposed rock in the world.
The park consists of a large number of "young" lakes (only tens of thousands of years old) contained by this ancient bedrock. A review of the Superior Province of the Canadian Shield, a product of Archean accretion.

Quetico Provincial Park is a large wilderness park in Northwestern Ontario, Canada, known for its excellent canoeing and 4, km 2 (1,acre) park shares its southern border with Minnesota's Boundary Waters Canoe Area Wilderness, which is part of the larger Superior National large wilderness parks are often collectively referred to as the Boundary Waters or the.
The Beardmore–Geraldton Belt occurs along the southern margin of the Archean Wabigoon subprovince, Superior Province, Ontario. Giga-fren The Algoman suite of granites and granodiorites, located within the Rainy Lake region of the Superior Province, intruded the Wabigoon –Quetico subprovince boundary about Ma.
Two main geological provinces of the Canadian Shield are represented in Ontario. The Superior Province and autochthonous cover sequences underlie approximately 80% of the province of Ontario, distributed mainly across the north and northwest. The Grenville Province, exposed in the southeast, and its autochthonous cover, make up the remainder.
rocks of the Canadian Shield, in particular, Archean rocks the Superior Province and Proterozoic rocks of the Southern Province (Fig 1). Three subprovinces of the Superior Province are represented; Wabigoon, Quetico, and the Abitibi—Wawa.
The Southern Province is subdivided into the Nipigon Plate and the Port Arthur Homocline, the northern. The Superior Craton is a stable crustal block covering Quebec, Ontario, and southeast Manitoba in Canada, and northern Minnesota in the United is the biggest craton among those formed during the Archean period.
A craton is a large part of the Earth's crust that has been stable and subjected to very little geological changes over a long time. The size of Superior Craton is about. The reticulate to anastomosed patterns produced by interaction of the fault sets, coupled with the large-scale variations in orientation of finite strain axes, suggest a transpressive tectonic regime related to oblique accretion of subprovinces in the late Archean.
The Archean Superior Province of the Canadian Shield and its lode gold. An overview of the research being conducted over the summer for Metal Earth. In order to reveal the fundamental geological processes that were responsible for the formation of mineral deposits in Superior Province, forty nine MSc, PhD students, research associates, and field assistants will be conducting research for the Metal Earth project across northern Ontario and Quebec.
SUPERIOR PROVINCE The Superior province is the world's largest relatively undisturbed Archean craton; it has been tectonically stable since Ga. It comprises the core of the Canadian Shield and extends southward into north-central United States.
The south half of the province.

High-grade Archean rocks are exposed in the central Superior Province ofthe Canadian Shield in the Kapuskasing StructuralZone, a partly fault-bounded region up to 50 x km. In migmatitic mafic gneiss, paragneiss, dioritic and tonalitic rocks, a lower-grade garnet-clinopyroxene-plagioclase (Gt-Cpx-PI) zone and patchy, higher-grade orthopyrox.

It is a relatively undifferentiated and partly foliated porphyritic granite-granodiorite con sisting, like many other Archean batholiths, of broadly related but not sequentially. Minnesota and the Quetico and Rainy Lake-Seine River faults in southern Ontario, resulted from a more brittle continuum of the transcurrent shear caused by collision along the GLTZ.In North America: to billion years ago of these fragments forms the Superior province, which is located in the south-central part of the Canadian Shield and is some 1, miles (2, km) Slave province ( miles [ km] wide) and the Nain province ( miles [ km] wide) are located in the northwestern and northeastern.Some one hundred years ago the British Government issued a "Blue Book" reporting the results of Captain Palliser's expedition to the Canadian west in which James Hector () published the first geologic observations on the Canadian Rocky Mountains.
Today the Southern Canadian Rockies rank among the best known mountain ranges of the world.
