Geology Of Canada
The geology of Canada is a subject of regional geology and covers the country of Canada, which is the second-largest country in the world. Geologic units and processes are investigated on a large scale to reach a synthesized picture of the geological development of the country. Geologically, Canada is one of the oldest regions in the world, with more than half of the region consisting of precambrian rocks that have been above sea level since the beginning of the Palaeozoic era. Canada's mineral resources are diverse and extensive. Across the Canadian Shield and in the north there are large iron, nickel, zinc, copper, gold, lead, molybdenum, and uranium reserves. Large diamond concentrations have been recently developed in the Arctic, making Canada one of the world's largest producers. Throughout the Shield there are many mining towns extracting these minerals. The largest, and best known, is Greater Sudbury, Sudbury, Ontario. Sudbury is an exception to the normal process of formin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geology Of Alberta
The geology of Alberta encompasses parts of the Canadian Rockies and thick sedimentary sequences, bearing coal, oil and natural gas, atop complex Precambrian crystalline basement rock. Geologic history, stratigraphy & tectonics The Precambrian granite and gneiss crystalline basement rocks beneath Alberta are extremely ancient, dating to the Archean and Proterozoic. The Slave Craton and Southern Alberta craton are the oldest units at more 2.5 billion years old, while younger units from the Proterozoic include the Wopmay orogeny, Great Slave Lake shear zone, Pre-Taltston basement, Taltson magmatic zone, Athabasca polymetamorphic terrane, Red Earth granulite domain, Kimiwan isotopic anomaly, Ksituan magmatic arc, Virgin River shear zone, Central Alberta intrusions and Lacombe domain. In many cases, Proterozoic deformation overprinted older Archean rocks. The Hudsonian Orogeny from 1.9 to 1.6 billion years ago was the last major regional metamorphic event.

Geology Of Saskatchewan
The geology of Saskatchewan can be divided into two main geological regions, the Precambrian Canadian Shield and the Phanerozoic Western Canadian Sedimentary Basin. Within the Precambrian shield exists the Athabasca sedimentary basin. Meteorite impacts have altered the natural geological formation processes. The prairies were most recently affected by glacial events in the Quaternary period. Canadian Shield The Canadian Shield, Precambrian shield, makes up the bedrock geology highlighted by rocks and lakes and a boreal forest area. There are transitional areas between boreal and tundra flora. The lower boundary of the Canadian Shield cuts across the province diagonally from the 57th parallel north, latitude 57 degrees in the northwest to 54th parallel north, 54 degrees in the south east. Three orogeny, orogenies formed the Precambrian shield, the Kenoran (Laurentian-Algoman orogeny, Algoman), Trans-Hudson Orogeny, Hudsonian (Penokean) and Grenville Orogeny. Kenorland, K ...

Geology Of Quebec
The geology of Quebec involves several different geologic provinces, made up of ancient Precambrian crystalline igneous and metamorphic rock, overlain by younger sedimentary rocks and soils. Most of southern Quebec is dominated by the Grenville Province, while the vast north is divided between the large Superior Province and the Churchill Province to the east, near Labrador. Geologic history, stratigraphy & tectonics The Grenville Province, which dominates southern Quebec, particularly the northern shore of the St. Lawrence formed beginning in the Archean, more than 2.5 billion years ago. Geologists subdivide the Grenville Province into the Allochthon along the river itself and the more northern Parautochthon. The Parautochthon is a band running parallel to the Grenville Front, which varies in width from Labrador to northeastern Georgian Bay on Lake Huron. Parautochthonous rocks are made up composed of ancient Archean and Proterozoic rocks that are highly deformed plutonic a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geology Of Prince Edward Island
The geology of Prince Edward Island formed as a result of strike-slip extension in the mountains formed by the Taconic orogeny, Salinic orogeny, and Acadian orogeny, which created an area of subsidence in the Gulf of St. Lawrence. The Maritime Rift resulted in the Magdalen Basin, which is actually a series of small basins surrounding the Gulf. In the Permian coal swamps formed in these basins, resulting in Atlantic Canada's extensive coal deposits, while in some cases, the swamps evaporated were replaced by gypsum evaporite. Up to 12 kilometers of late Paleozoic The Paleozoic ( , , ; or Palaeozoic) Era is the first of three Era (geology), geological eras of the Phanerozoic Eon.

Geology Of Ontario
The geology of Ontario is the study of rock formations in the most populated province in Canada- it is home to some of the oldest rock on Earth. The geology in Ontario consists of ancient Precambrian igneous and metamorphic rock which sits under younger, sedimentary rocks and soils. Around 61% of Ontario is covered by the Canadian Shield. The shield, as a whole, can further be divided into three sections- these are known as provinces. The northwestern parts of the Shield, located north and west of Sudbury, are known as the Superior province. This is the largest of the three sections, covering 70% of the Canadian Shield portion in Ontario. The Southern province is a narrow region from Sault Ste. Marie to Kirkland Lake. The South central part is dominated by the Grenville Province but flanked by two basins of Phanerozoic materials. Abundant mineral deposits are found here and as a result are mined extensively. Canadian Shield About 61% of Ontario is covered by the Canadian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geology Of Nunavut
The geology of Nunavut began to form nearly three billion years ago in the Archean and the territory preserves some of the world's oldest rock units. Geologic History, Stratigraphy & Tectonics Archean Archean rocks dominate much of the territory's surface and places with overlying rock. Greenstone belts are common together with migmatite gneiss, granodiorite, and quartz monzonite, on the Melville Peninsula and northern Baffin Island, as well as the southwest mainland. Lenses and bands of amphibolite, granitoid and metasedimentary rocks are common in these areas, along with less common ultramafic rocks. Gold and other base metals are widespread as mineralization in siliclastic, felsic, mafic and ironstone rocks of the greenstone belts. The George Lake, Boston and Ulu deposits are all hosted in the Yellowknife Supergroup of the Slave Craton in the west as well as the Lupin gold mine. In the western Churchill Province of south-central Nunavut are the Noomut, Heninga Lake and Melia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geology Of Northwest Territories
The geology of the Northwest Territories has been mapped in different quadrangles by the Canadian government. The region has some of the oldest rocks in the world and among the oldest in North America, formed from several sections of stable craton continental crust, including the Slave Craton, Rae Craton and Hearne Craton. These rocks form the Archean and Proterozoic Precambrian basement rock of the region and are the subject of extensive research to understand continental crust and tectonic conditions on the early Earth. Geologic History, Stratigraphy & Tectonics The Hearne Craton and Rae Craton are underlain by Archean metasedimentary and metavolcanic rocks. Quartz arenite in the Rae Craton has been interpreted as possible passive margin or rift deposits. Around the world, greenstone belts are a hallmark of ancient Precambrian rocks. The Ennadai-Rankin greenstone belt is the second largest in Canada and displays felsic volcanic and volcaniclastic rocks, as well as mafic rock ...

Geology Of Nova Scotia
The Nova Scotia peninsula is a peninsula on the Atlantic coast of North America. It is called ''Enmigtaqamu'g'' in the Mi'kmaw language. Location The Nova Scotia peninsula is part of the province of Nova Scotia, Canada and is connected to the neighbouring province of New Brunswick through the Isthmus of Chignecto. It fronts the open Atlantic Ocean on the south and southeast, the Gulf of Maine to the west, the Bay of Fundy and its sub-basins to the northwest, the Northumberland Strait to the north, and the Strait of Canso to the east. The narrow and deep waters of the Strait of Canso separate the peninsula from Cape Breton Island, the second largest land mass constituting the province of Nova Scotia. In addition to Cape Breton Island, other much smaller islands are geologically associated with the Nova Scotia peninsula, including Boularderie Island, Brier Island, Long Island, Pictou Island, Tancook Island and various smaller islands along the Atlantic coast.

Geology Of Newfoundland And Labrador
The geology of Newfoundland and Labrador includes basement rocks formed as part of the Grenville Province in the west and Labrador and the Avalonian microcontinent in the east. Extensive tectonic changes, metamorphism and volcanic activity have formed the region throughout Earth history. Newfoundland In contrast to neighboring Labrador, the island of Newfoundland is largely underlain by younger rocks. The Churchill, Nain, Superior and Grenville Province present in Labrador were all small continents or pieces of continental lithosphere that joined to form sections of the proto-North American continent Laurentia and the broad stable region known as the Canadian Shield. By the end of the Precambrian in the Neoproterozoic, continental crust which had come into existence in the Archean nearly 2.5 billion years had already experienced up to eight supercontinent cycles. In the late Precambrian and Paleozoic, Avalonia (named after the Avalon Peninsula in Newfoundland) formed as a volcanic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
