Fort Simpson Formation
The Fort Simpson Formation is a stratigraphical unit of Devonian age in the Western Canadian Sedimentary Basin.

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 ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alberta
Alberta ( ) is one of the thirteen provinces and territories of Canada. It is part of Western Canada and is one of the three prairie provinces. Alberta is bordered by British Columbia to the west, Saskatchewan to the east, the Northwest Territories (NWT) to the north, and the U.S. state of Montana to the south. It is one of the only two landlocked provinces in Canada (Saskatchewan being the other). The eastern part of the province is occupied by the Great Plains, while the western part borders the Rocky Mountains. The province has a predominantly continental climate but experiences quick temperature changes due to air aridity. Seasonal temperature swings are less pronounced in western Alberta due to occasional Chinook winds. Alberta is the fourth largest province by area at , and the fourth most populous, being home to 4,262,635 people. Alberta's capital is Edmonton, while Calgary is its largest city. The two are Alberta's largest census metropolitan areas. More tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Woodbend Group
The Woodbend Group is a stratigraphical unit of Frasnian age in the Western Canadian Sedimentary Basin. It was first described in the ''British American Pyrcz No. 1'' well by Imperial Oil geological staff in 1950. Lithology The Formation is composed of crystalline and dolomitized limestone ( Cooking Lake Formation) in off-reef areas, bituminous shale and argillaceous limestone, detrital limestone (reef fallout), stromatoporoid calcarenite ( Duvernay Formation), gray shale, argillaceous limestone, argillaceous dolomite, crystalline dolomite ( Ireton Formation). In reef build-ups, it consists of massive limestone and dolomite with porosity (Leduc Formation). Hydrocarbon production Oil is produced from the Leduc Formation in central Alberta since the early 1950s. Shale gas and liquids are extracted from the Duvernay Formation using horizontal drilling and multi-stage hydraulic fracturing. Several project test the economic viability of extracting bitumen from the Grosmont ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Imperial Formation is the name of two distinct and unrelated geologic formations in North America, of different geologic Eras. Separate formations Canadian Paleozoic Era formation The older Imperial Formation occurs in the Northwest Territories of Canada. It preserves fossils dating back to the Devonian period of the Paleozoic Era. Californian Cenozoic Era formation The younger Imperial Formation occurs in the Colorado Desert, in Imperial County of Southern California.

Liard River
The Liard River of the North American boreal forest flows through Yukon, British Columbia and the Northwest Territories, Canada. Rising in the Saint Cyr Range of the Pelly Mountains in southeastern Yukon, it flows southeast through British Columbia, marking the northern end of the Rocky Mountains and then curving northeast back into Yukon and Northwest Territories, draining into the Mackenzie River at Fort Simpson, Northwest Territories. The river drains approximately of boreal forest and muskeg. Geography The river habitats are a subsection of the Lower Mackenzie Freshwater Ecoregion. The area around the river in Yukon is called the ''Liard River Valley'', and the Alaska Highway follows the river for part of its route. This surrounding area is also referred to as the ''Liard Plain'', and is a physiographic section of the larger Yukon–Tanana Uplands province, which in turn is part of the larger Intermontane Plateaus physiographic division. The Liard River is a crossing ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
