Bjorne Formation
The Bjorne Formation is a formation of sandstones and shales in the Canadian Arctic Archipelago. The southern edge of the formation includes petroleum reserves in Melville Island. The basin also includes Mackenzie King Island, Lougheed Island and portions of Prince Patrick Island, Borden Island, Ellef Ringnes Island, Amund Ringnes Island, and Cornwall Island. The formation underlies the Murray Harbour Formation and overlies the Blind Fiord, Lindstrom and Trold Fiord Formations. Oil and gas deposits are confirmed through the basin. The southern and eastern margins are more than 1000 meters, sometimes nearly 2000 meters, thick.

Geological Formation
A geological formation, or simply formation, is a body of rock having a consistent set of physical characteristics ( lithology) that distinguishes it from adjacent bodies of rock, and which occupies a particular position in the layers of rock exposed in a geographical region (the stratigraphic column). It is the fundamental unit of lithostratigraphy, the study of strata or rock layers. A formation must be large enough that it can be mapped at the surface or traced in the subsurface. Formations are otherwise not defined by the thickness of their rock strata, which can vary widely. They are usually, but not universally, tabular in form. They may consist of a single lithology (rock type), or of alternating beds of two or more lithologies, or even a heterogeneous mixture of lithologies, so long as this distinguishes them from adjacent bodies of rock. The concept of a geologic formation goes back to the beginnings of modern scientific geology. The term was used by Abraham Gottlob Wer ...

Mackenzie King Island
Mackenzie King Island is one of the uninhabited Queen Elizabeth Islands in northern Canada. It lies north of Melville Island and south of Borden Island, and like them is divided when it comes to administration. Most of the island is in Northwest Territories, while its easternmost portion lies in Nunavut. The border runs along the 110th meridian west. Mackenzie King has an area of , long in northeast or in southeast and wide, making it the 116th largest island in the world, and Canada's 26th largest island. History The first known visit to the island was by Vilhjalmur Stefansson in 1915, and it was later named for William Lyon Mackenzie King William Lyon Mackenzie King (December 17, 1874 – July 22, 1950) was a Canadian statesman and politician who served as the tenth prime minister of Canada for three non-consecutive terms from 1921 to 1926, 1926 to 1930, and 1935 to 1948.

Sandstone Formations Of Canada
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions. Rock formations that are primarily composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Quartz-bearing sandstone can be changed into quartzite through metamorphism, usually related to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triassic Canada
The Triassic ( ) is a geologic period and system which spans 50.6 million years from the end of the Permian Period 251.902 million years ago ( Mya), to the beginning of the Jurassic Period 201.36 Mya. The Triassic is the first and shortest period of the Mesozoic Era. Both the start and end of the period are marked by major extinction events. The Triassic Period is subdivided into three epochs: Early Triassic, Middle Triassic and Late Triassic. The Triassic began in the wake of the Permian–Triassic extinction event, which left the Earth's biosphere impoverished; it was well into the middle of the Triassic before life recovered its former diversity. Three categories of organisms can be distinguished in the Triassic record: survivors from the extinction event, new groups that flourished briefly, and other new groups that went on to dominate the Mesozoic Era. Reptiles, especially archosaurs, were the chief terrestrial vertebrates during this time. A specialized subgroup of archosaurs ...

Geologic Formations Of Canada
Geology () is a branch of natural science concerned with Earth and other astronomical objects, the features or rocks of which it is composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology, and so is treated as one major aspect of integrated Earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface, and the processes that have shaped that structure. It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks. By combining these tools, geologists are able to chronicle the geological history of the Earth as a whole, and also to demonstrate the age of the Earth. Geology provides the primary evidence for plate tectonics, the evolutionary history of life, and the Earth's past climates. Geologists broadly study the properties and processes of ...

Cornwall Island (Ontario)
Cornwall Island () is an island in the Saint Lawrence River, directly south of the city of Cornwall. The island is located completely within Canada, but it is also part of the Akwesasne Mohawk reserve, which straddles the Canada–United States border and the Quebec–Ontario border. The Seaway International Bridge, with a channel crossing on each side of the island, provides road access to Cornwall Island from both Canada and the United States. Disputes with Canada The area has been the scene of several disputes by Akwesasne residents on their rights to cross the border unimpeded, as provided under the 1795 Jay Treaty. Canadian authorities have been increasingly concerned about large-scale cigarette smuggling along this route. There have been arrests and seizures of goods in the past. There is concern among both of the large nations about smuggling as well of liquor, drugs, and migrants through Akwesasne. Residents of Akwesasne have had their own internal disputes that have somet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
