La Moinerie Crater
La Moinerie is an impact crater in Quebec, Canada. It is 8 km in diameter and the age is estimated to be 400 ± 50 million years (Silurian or Devonian). The crater is exposed to the surface and filled with water, forming Lac La Moinerie. Glaciers have eroded many of La Moinerie crater's original physical features, including much of the central uplift. It is located in Rivière-Koksoak, in the Kativik The Kativik Regional Government (french: Administration régionale Kativik, KGR) encompasses most of the Nunavik region of Quebec. Nunavik is the northern half of the Nord-du-Québec administrative region and includes all the territory north of ... territory. References Further reading * Gold, D.P. Tanner, J.G. and Halliday, D.W.

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 ...

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 ...

Silurian
The Silurian ( ) is a geologic period and system spanning 24.6 million years from the end of the Ordovician Period, at million years ago ( Mya), to the beginning of the Devonian Period, Mya. The Silurian is the shortest period of the Paleozoic Era. As with other geologic periods, the rock beds that define the period's start and end are well identified, but the exact dates are uncertain by a few million years. The base of the Silurian is set at a series of major Ordovician–Silurian extinction events when up to 60% of marine genera were wiped out. One important event in this period was the initial establishment of terrestrial life in what is known as the Silurian-Devonian Terrestrial Revolution: vascular plants emerged from more primitive land plants, dikaryan fungi started expanding and diversifying along with glomeromycotan fungi, and three groups of arthropods (myriapods, arachnids and hexapods) became fully terrestrialized. A significant evolutionary milestone during ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Devonian
The Devonian ( ) is a geologic period and system of the Paleozoic era, spanning 60.3 million years from the end of the Silurian, million years ago (Mya), to the beginning of the Carboniferous, Mya. It is named after Devon, England, where rocks from this period were first studied. The first significant adaptive radiation of life on dry land occurred during the Devonian. Free-sporing vascular plants began to spread across dry land, forming extensive forests which covered the continents. By the middle of the Devonian, several groups of plants had evolved leaves and true roots, and by the end of the period the first seed-bearing plants appeared. The arthropod groups of myriapods, arachnids and hexapods also became well-established early in this period, after starting their expansion to land at least from the Ordovician period. Fish reached substantial diversity during this time, leading the Devonian to often be dubbed the Age of Fishes. The placoderms began dominating ...

Rivière-Koksoak, Quebec
Rivière-Koksoak is a very large unorganized territory (Quebec), unorganized territory in the Kativik Regional Government territory in the Nord-du-Québec region of Quebec. It is named after the Koksoak River. It consists of nearly the entire eastern part of northernmost Quebec. Bordering it to the west is the other large unorganized territory in Kativik, Baie-d'Hudson, Quebec, Baie-d'Hudson. Its population in the Canada 2011 Census was 0; enclaved within it, however, are various northern village (Quebec), northern villages (i.e., Inuit communities) and one (uninhabited) Naskapi village municipality. In the Canada 2006 Census, 2006 census it had a population of 15. References {{DEFAULTSORT:Riviere-Koksoak, Quebec Unorganized territories in Nord-du-Québec ...

Kativik, Quebec
Kativik is a territory equivalent to a regional county municipality (TE) of Quebec, with geographical code 992. Its land area is 443,372.20 km2 (171,186.96 sq mi), and its population was 12,090 at the 2011 Census of Canada. Together with the TEs of Jamésie and Eeyou Istchee, it forms the administrative region and census division (CD) of Nord-du-Québec. The TE of Kativik is coextensive with the territory of the Kativik Regional Government. It comprises all of Nunavik except the Cree reserved land (TC) of Whapmagoostui and the Cree village municipality (VC) also called Whapmagoostui, which belong to Eeyou Istchee TE. Subdivisions The TE of Kativik consists of the following municipal units: * the unorganized territories (NO) of: :* Rivière-Koksoak :* Baie-d'Hudson * the Naskapi village (VK) of: :* Kawawachikamach (but not the Naskapi reserved land (TK) of the same name, Kawawachikamach, which lies detached, to its south, near Schefferville in the Caniapiscau Regio ...
