ÃŽle Rouleau Crater
Île Rouleau is an impact crater in Baie-James, Quebec, Canada, located on a small, uninhabited island in Lake Mistassini in the centre of the province. The crater is in diameter and the age is estimated to be less than 300 million years (Permian The Permian ( ) is a geologic period and stratigraphic system which spans 47 million years from the end of the Carboniferous Period million years ago (Mya), to the beginning of the Triassic Period 251.9 Mya. It is the last period of the Paleoz ... or younger). Part of the crater is exposed to the surface, but most of it is under the waters of the lake. References Further reading * Caty, J.

Lake Mistassini
Lake Mistassini () is the largest natural lake by surface area in the province of Quebec, Canada, with a total surface area of approximately and a net area (water surface area only) of . It is located in the Jamésie region of the province, approximately east of James Bay. The Cree town of Mistissini is located on Watson Peninsula in the south-east corner of the lake, which separates Baie du Poste from Abatagouche Bay. Extensive forests of spruce, birch, pine, and fir trees, which support a booming forestry industry, surround the lake. Significant tributaries flowing into the lake include: Chalifour, Pépeshquasati, Takwa, Témiscamie, and Wabissinane. Other nearby lakes include Lake Albanel and Lake Troilus. Etymology The name Mistassini came from the Cree or Montagnais , and means "large rock"; it probably refers a large glacial erratic stone, about high, located near the outlet of Lake Mistassini into the Rupert River. Over the centuries, it went through many name ch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Permian
The Permian ( ) is a geologic period and stratigraphic system which spans 47 million years from the end of the Carboniferous Period million years ago (Mya), to the beginning of the Triassic Period 251.9 Mya. It is the last period of the Paleozoic Era; the following Triassic Period belongs to the Mesozoic Era. The concept of the Permian was introduced in 1841 by geologist Sir Roderick Murchison, who named it after the region of Perm in Russia. The Permian witnessed the diversification of the two groups of amniotes, the synapsids and the sauropsids ( reptiles). The world at the time was dominated by the supercontinent Pangaea, which had formed due to the collision of Euramerica and Gondwana during the Carboniferous. Pangaea was surrounded by the superocean Panthalassa. The Carboniferous rainforest collapse left behind vast regions of desert within the continental interior. Amniotes, which could better cope with these drier conditions, rose to dominance in place of their am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quebec
Quebec ( ; )According to the Canadian government, ''Québec'' (with the acute accent) is the official name in Canadian French and ''Quebec'' (without the accent) is the province's official name in Canadian English is one of the thirteen provinces and territories of Canada. It is the largest province by area and the second-largest by population. Much of the population lives in urban areas along the St. Lawrence River, between the most populous city, Montreal, and the provincial capital, Quebec City. Quebec is the home of the Québécois nation. Located in Central Canada, the province shares land borders with Ontario to the west, Newfoundland and Labrador to the northeast, New Brunswick to the southeast, and a coastal border with Nunavut; in the south it borders Maine, New Hampshire, Vermont, and New York in the United States. Between 1534 and 1763, Quebec was called ''Canada'' and was the most developed colony in New France. Following the Seven Years' War, Quebec b ...

Nord-du-Québec
Nord-du-Québec (; en, Northern Quebec) is the largest, but the least populous, of the seventeen administrative regions of Quebec, Canada. With nearly of land area, and very extensive lakes and rivers, it covers much of the Labrador Peninsula and about 55% of the total land surface area of Quebec, while containing a little more than 0.5% of the population. Before 1912, the northernmost part of this region was part of the Ungava District of the Northwest Territories, and until 1987 it was referred to as Nouveau-Québec, or ''New Quebec''. It is bordered by Hudson Bay and James Bay in the west, Hudson Strait and Ungava Bay in the north, Labrador in the northeast, and the administrative regions of Abitibi-Témiscamingue, Mauricie, Saguenay–Lac-Saint-Jean, and Côte-Nord in the south and southeast. The Nord-du-Québec region is part of the territory covered by the James Bay and Northern Quebec Agreement of 1975; other regions covered (in part) by this Agreement include Côt ...

Baie-James
The Municipality of Baie-James (french: Municipalité de Baie-James) was a municipality in northern Quebec, Canada, which existed from 1971 to 2012. Located to the east of James Bay, Baie-James covered of land, making it the largest incorporated municipality in Canada — only eight Unorganized area (Canada), unorganized territories were larger. Its territory almost entirely (about 98%) covered the administrative region of Jamésie, although it contained less than five percent of the population. Essentially, it was the remainder of the Jamésie Territory's land after all of the major population centres were removed. On July 24, 2012, the Quebec government signed an accord with the Cree that would result in the abolition of Baie-James and the creation of a regional government known as Eeyou Istchee James Bay Territory. The hydroelectric power plants of the James Bay Project, La Grande Complex were all located within the municipal boundaries of Baie-James, making the municipalit ...

Impact Crater
An impact crater is a circular depression in the surface of a solid astronomical object formed by the hypervelocity impact of a smaller object. In contrast to volcanic craters, which result from explosion or internal collapse, impact craters typically have raised rims and floors that are lower in elevation than the surrounding terrain. Lunar impact craters range from microscopic craters on lunar rocks returned by the Apollo Program and small, simple, bowl-shaped depressions in the lunar regolith to large, complex, multi-ringed impact basins. Meteor Crater is a well-known example of a small impact crater on Earth. Impact craters are the dominant geographic features on many solid Solar System objects including the Moon, Mercury, Callisto, Ganymede and most small moons and asteroids. On other planets and moons that experience more active surface geological processes, such as Earth, Venus, Europa, Io and Titan, visible impact craters are less common because they become eroded ...

Landforms Of Nord-du-Québec
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features. Mountains, hills, plateaux, and plains are the fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
