Muskiki Formation
The Muskiki Formation is a stratigraphical unit of Late Cretaceous age in the Western Canadian Sedimentary Basin. The formation is named after Muskiki Lake and Muskiki Creek, a tributary of the Cardinal River, and was first described in an outcrop along the Thistle Creek, north of Muskiki Lake, in the Bighorn Range, by D.F. Stott in 1963. The name is of Cree origin ("maskihkîy"), meaning ''medicine''. Lithology The Muskiki Formation is composed of shale with pebbly mudstone. Poorly sorted sandstone and concretionary beds also occur. In the western areal it becomes more silty. Distribution The Muskiki Formation is thick at its type locality at Thistle Creek. It thins out towards the south and east. It occurs in the Canadian Rockies foothills from the Highwood River in the south to the Berland River, north of the Athabasca River and into north-eastern British Columbia. Relationship to other units The Muskiki Formationis is part of the Smoky Group. It is conformably underlain by ...

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 ...

Mudstone
Mudstone, a type of mudrock, is a fine-grained sedimentary rock whose original constituents were clays or muds. Mudstone is distinguished from '' shale'' by its lack of fissility (parallel layering).Blatt, H., and R.J. Tracy, 1996, ''Petrology.'' New York, New York, W. H. Freeman, 2nd ed, 529 pp. The term ''mudstone'' is also used to describe carbonate rocks (limestone or dolomite) that are composed predominantly of carbonate mud. However, in most contexts, the term refers to siliciclastic mudstone, composed mostly of silicate minerals. The NASA Curiosity rover has found deposits of mudstone on Mars that contain organic substances such as propane, benzene and toluene. Definition There is not a single definition of mudstone that has gained general acceptance,Boggs 2006, p.143 though there is wide agreement that mudstones are fine-grained sedimentary rocks, composed mostly of silicate grains with a grain size less than . Individual grains this size are too small to be disting ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Blackstone Formation, Canada
The Alberta Group is a stratigraphical unit of Cenomanian to early Campanian age in the Lewis overthrust in the Western Canadian Sedimentary Basin. It takes the name from the province of Alberta, and was first described in outcrops along the Highwood River in southern Alberta by G.S. Hume in 1930.Hume, G.S., 1930. The Highwood-Jumpingpound Anticline, with Notes on Turner Valley, New Black Diamond and Priddis Valley Structures, Alberta; Geological Survey of Canada, Summary Report 1929, Part B, pp. 1-24. Lithology The Alberta Group is composed of silty shale for the most part. Two thick shale deposits (Blackstone Formation and Wapiabi Formation) are present above and below a sandstone sequence (the Cardium Formation). Sideritic concretions and thin argillaceous limestone beds are present within the shale stacks. Oil/gas production Gas is produced from the Cardium Formation in Yellowhead County.

Northern Alberta
Northern Alberta is a geographic region located in the Canadian province of Alberta. An informally defined cultural region, the boundaries of Northern Alberta are not fixed. Under some schemes, the region encompasses everything north of the centre of the Calgary–Edmonton Corridor, including most of the province's landmass as well as its capital, Edmonton. Other schemes place Edmonton and its surrounding farmland in Central Alberta, limiting Northern Alberta to the northern half of the province, where forestry, oil, and gas are the dominant industries. Its primary industry is oil and gas, with large heavy oil reserves being exploited at the Athabasca oil sands and Wabasca area in the east of the region. Natural gas is extracted in Peace region and Chinchaga-Rainbow areas in the west, and forestry and logging are also developed in the boreal forests of this region. As of 2011, the region had a population of approximately 386,000. Geography Various definitions exist of North ...

Kaskapau Formation
The Kaskapau Formation is a geological formation in North America whose strata date back to the Late Cretaceous. The name derives from ''kaskapahtew'' (ᑲᐢᑲᐸᐦᑌᐤ), the Cree word for "smoky". It was first described on the banks of the Smoky River, close to the confluence with the Puskwaskau River by F.H. McLearn in 1926. Geographical distribution The formation is thick in the Peace River and Smoky River area, and thickens up to in the foothills of the Northern Rocky Mountains in British Columbia. It is exposed along the Peace River near Dunvegan, as well as in the Smoky River area. The formation is part of the Smoky River Group, and is conformably overlain by the Bad Heart Formation in the western area, and unconformably by the Cardium Formation in the Pouce Coupe River area. It is conformable underlain by the Dunvegan Formation. The Kaskapau Formation is equivalent to the Colorado Group shale in central Alberta. It is equivalent to the upper Blackstone Forma ...

British Columbia
British Columbia (commonly abbreviated as BC) is the westernmost province of Canada, situated between the Pacific Ocean and the Rocky Mountains. It has a diverse geography, with rugged landscapes that include rocky coastlines, sandy beaches, forests, lakes, mountains, inland deserts and grassy plains, and borders the province of Alberta to the east and the Yukon and Northwest Territories to the north. With an estimated population of 5.3million as of 2022, it is Canada's third-most populous province. The capital of British Columbia is Victoria and its largest city is Vancouver. Vancouver is the third-largest metropolitan area in Canada; the 2021 census recorded 2.6million people in Metro Vancouver. The first known human inhabitants of the area settled in British Columbia at least 10,000 years ago. Such groups include the Coast Salish, Tsilhqotʼin, and Haida peoples, among many others. One of the earliest British settlements in the area was Fort Victoria, established ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Athabasca River
The Athabasca River (French: ''Rivière Athabasca'') is a river in Alberta, Canada, which originates at the Columbia Icefield in Jasper National Park and flows more than before emptying into Lake Athabasca. Much of the land along its banks is protected in national and provincial parks, and the river is designated a Canadian Heritage River for its historical and cultural importance. The scenic Athabasca Falls is located about upstream from Jasper. Etymology The name ''Athabasca'' comes from the Woods Cree word , which means "herethere are plants one after another", likely a reference to the spotty vegetation along the river. Course The Athabasca River originates in Jasper National Park, in an unnamed lake at the toe of the Columbia Glacier within the Columbia Icefield, between Mount Columbia, Snow Dome, and the Winston Churchill Range, at an elevation of approximately . It travels before draining into the Peace-Athabasca Delta near Lake Athabasca south of Fort Chipewyan. Fr ...

Highwood River
The Highwood River is a tributary of the Bow River in southwestern Alberta, Canada. Course The Highwood originates in the Canadian Rockies in Peter Lougheed Provincial Park, in the Highwood Pass below Mount Arethusa. It flows south and is paralleled by the Kananaskis Trail between Elbow-Sheep Wildland Provincial Park, Don Getty Wildland Provincial Park, and ''Emerson Creek Park''. It turns east and flows along Highway 541 and through the community of Longview. Continuing east, it passes through High River, ending when it enters the Bow River southeast of Calgary. Recreation The river is known for flyfishing. A variety of trout species live in the river, including native bull trout. In springtime when the snow is melting the river offers white water rafting. Flooding The Highwood River is subject to frequent flooding. Flood events of exceptional magnitude occurred in 1894, 1899, 1902, 1908, 1912, 1923, 1929, 1932, 1942, 1995, 2005 and 2013.

Canadian Rockies
The Canadian Rockies (french: Rocheuses canadiennes) or Canadian Rocky Mountains, comprising both the Alberta Rockies and the British Columbian Rockies, is the Canadian segment of the North American Rocky Mountains. It is the easternmost part of the Canadian Cordillera, which is the northern segment of the North American Cordillera, the expansive system of interconnected mountain ranges between the Interior Plains and the Pacific Coast that runs northwest–southeast from central Alaska to the Isthmus of Tehuantepec in Mexico. Canada officially defines the Rocky Mountains system as the mountain chains east of the Rocky Mountain Trench extending from the Liard River valley in northern British Columbia to the Albuquerque Basin in New Mexico, not including the Mackenzie, Richardson and British Mountains/Brooks Range in Yukon and Alaska (which are all included as the "Arctic Rockies" in the United States' definition of the Rocky Mountains system).

Silt
Silt is granular material of a size between sand and clay and composed mostly of broken grains of quartz. Silt may occur as a soil (often mixed with sand or clay) or as sediment mixed in suspension with water. Silt usually has a floury feel when dry, and lacks plasticity when wet. Silt also can be felt by the tongue as granular when placed on the front teeth (even when mixed with clay particles). Silt is a common material, making up 45% of average modern mud. It is found in many river deltas and as wind-deposited accumulations, particularly in central Asia, north China, and North America. It is produced in both very hot climates (through such processes as collisions of quartz grains in dust storms) and very cold climates (through such processes as glacial grinding of quartz grains.) Loess is soil rich in silt which makes up some of the most fertile agricultural land on Earth. However, silt is very vulnerable to erosion, and it has poor mechanical properties, making construction ...

Sandstone
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]   |

Shale
Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2 Si2 O5( OH)4) and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite.Blatt, Harvey and Robert J. Tracy (1996) ''Petrology: Igneous, Sedimentary and Metamorphic'', 2nd ed., Freeman, pp. 281–292 Shale is characterized by its tendency to split into thin layers ( laminae) less than one centimeter in thickness. This property is called '' fissility''. Shale is the most common sedimentary rock. The term ''shale'' is sometimes applied more broadly, as essentially a synonym for mudrock, rather than in the more narrow sense of clay-rich fissile mudrock. Texture Shale typically exhibits varying degrees of fissility. Because of the parallel orientation of clay mineral flakes in shale, it breaks into thin layers, often splintery and usually parallel to the otherwise indistinguishable beddin ...
