Pine Point Formation
The Pine Point Formation is a stratigraphical unit of Givetian age in the Western Canadian Sedimentary Basin. It takes the name from Pine Point, a promontory (and former townsite) on the south shore of the Great Slave Lake, west of Fort Resolution, and was first described in outcrop on the shore of the lake between Pine Point and Fort Resolution by A.E. Cameron in 1918.Cameron, A.E., 1918. Explorations in the vicinity of Great Slave Lake; Geological Survey of Canada, Summary Report 1917, Part C, pp. 21-28.

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 ...

Fitzgerald Formation
The FitzGerald/FitzMaurice Dynasty is a noble and aristocratic dynasty of Cambro-Norman, Anglo-Norman and later Hiberno-Norman origin. They have been peers of Ireland since at least the 13th century, and are described in the Annals of the Four Masters as having become "more Irish than the Irish themselves" or Gaels, due to assimilation with the native Gaelic aristocratic and popular culture. The dynasty has also been referred to as the Geraldines and Ireland's largest landowners. They achieved power through the conquest of large swathes of Irish territory by the sons and grandsons of Gerald of Windsor (c. 1075 – 1135). Gerald of Windsor ( Gerald FitzWalter) was the first Castellan of Pembroke Castle in Wales, and became the male progenitor of the FitzMaurice and FitzGerald Dynasty ("fitz", from the Anglo-Norman ''fils'' indicating "sons of" Gerald). His father, Baron Walter FitzOther, was the first Constable and Governor of Windsor Castle for William the Conqueror, and was ...

Stratigraphy Of British Columbia
Stratigraphy is a branch of geology concerned with the study of rock layers (strata) and layering (stratification). It is primarily used in the study of sedimentary and layered volcanic rocks. Stratigraphy has three related subfields: lithostratigraphy (lithologic stratigraphy), biostratigraphy (biologic stratigraphy), and chronostratigraphy (stratigraphy by age). Historical development Catholic priest Nicholas Steno established the theoretical basis for stratigraphy when he introduced the law of superposition, the principle of original horizontality and the principle of lateral continuity in a 1669 work on the fossilization of organic remains in layers of sediment. The first practical large-scale application of stratigraphy was by William Smith in the 1790s and early 19th century. Known as the "Father of English geology", Smith recognized the significance of strata or rock layering and the importance of fossil markers for correlating strata; he created the first geologic map o ...

Keg River Formation
The Keg River Formation is a stratigraphic unit of Givetian age in the Western Canada Sedimentary Basin.

Law in 1955. Lithology The Keg River Formation is composed of dark dolomite with intercrystalline or vuggy porosity and wackestone limestone. The Rainbow Member and upper Keg River Member are reef formations deposited in the Rainbow, Zama and Bitscho sub-basins.

Horn River Formation
The Horn River Formation (also ''Horn River Shale'') is a stratigraphic unit of Devonian (early Givetian to late Frasnian) age in the Western Canadian Sedimentary Basin. It is a thick sequence of marine sediments that was first described in outcrop on the banks of the Horn River, a tributary of the Mackenzie River, in the Northwest Territories (at the time District of Mackenzie) by Whittaker in 1922, and it takes its name from that river. In 1963 it was redefined in the subsurface of the Fort Nelson area of British Columbia (well Fort Nelson a-95-J/94-J-10) by F.F. Gray and J.R. Kassube. It is significant for its shale gas resources. Lithology The Horn River Formation is composed of dark siliceous and calcareous shale, and argillaceous bituminous limestone. Stratigraphy The Horn River Formation is included in the Beaverhill Lake Group. It is subdivided into the following members, from top to base: * Muskwa Member: bituminous, mildly radioactive shale * Otter Park Member ...

Northwest Territories
The Northwest Territories (abbreviated ''NT'' or ''NWT''; french: Territoires du Nord-Ouest, formerly ''North-Western Territory'' and ''North-West Territories'' and namely shortened as ''Northwest Territory'') is a federal territory of Canada. At a land area of approximately and a 2016 census population of 41,790, it is the second-largest and the most populous of the three territories in Northern Canada. Its estimated population as of 2022 is 45,605. Yellowknife is the capital, most populous community, and only city in the territory; its population was 19,569 as of the 2016 census. It became the territorial capital in 1967, following recommendations by the Carrothers Commission. The Northwest Territories, a portion of the old North-Western Territory, entered the Canadian Confederation on July 15, 1870. Since then, the territory has been divided four times to create new provinces and territories or enlarge existing ones. Its current borders date from April 1, 1999, when the ...

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] |

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] |
