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 ...

Edmonton
Edmonton ( ) is the capital city of the Canadian province of Alberta. Edmonton is situated on the North Saskatchewan River and is the centre of the Edmonton Metropolitan Region, which is surrounded by Alberta's central region. The city anchors the north end of what Statistics Canada defines as the " Calgary–Edmonton Corridor". As of 2021, Edmonton had a city population of 1,010,899 and a metropolitan population of 1,418,118, making it the fifth-largest city and sixth-largest metropolitan area (CMA) in Canada. Edmonton is North America's northernmost large city and metropolitan area comprising over one million people each. A resident of Edmonton is known as an ''Edmontonian''. Edmonton's historic growth has been facilitated through the absorption of five adjacent urban municipalities ( Strathcona, North Edmonton, West Edmonton, Beverly and Jasper Place) hus Edmonton is said to be a combination of two cities, two towns and two villages./ref> in addition to a series ...

Geological Unit
A stratigraphic unit is a volume of rock of identifiable origin and relative age range that is defined by the distinctive and dominant, easily mapped and recognizable petrographic, lithologic or paleontologic features (facies) that characterize it. Units must be ''mappable'' and ''distinct'' from one another, but the contact need not be particularly distinct. For instance, a unit may be defined by terms such as "when the sandstone component exceeds 75%". Lithostratigraphic units Sequences of sedimentary and volcanic rocks are subdivided the basis of their shared or associated lithology. Formally identified lithostratigraphic units are structured in a hierarchy of lithostratigraphic rank, higher rank units generally comprising two or more units of lower rank. Going from smaller to larger in rank, the main lithostratigraphic ranks are Bed, Member, Formation, Group and Supergroup. Formal names of lithostratigraphic units are assigned by geological surveys. Units of formation or hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rimbey
Rimbey is a town in central Alberta, Canada. It is located at the junction of Highways 20 and 53 in the Blindman River valley area approximately northwest of Red Deer and southwest of Edmonton. Provincially, Rimbey is part of the Rimbey-Rocky Mountain House-Sundre electoral district and federally in the Wetaskiwin riding. History Officially made a community in 1902, the first name given to the settlement at the turn of the century was Kansas Ridge as many of the settlers originated from the American state of Kansas. Among them were the three Rimbey brothers (Sam, Ben, and Jim) for whom the town was officially named after in 1904. The Rimbeys moved to Canada from Scott County, Illinois having moved to Illinois in the 1830s from Maryland. They were born in Pennsylvania. In 1919 the Lacombe and Blindman Valley Electric Railway (later part of the Canadian Pacific Railway) reached Rimbey, and there was much enthusiasm for the "new town" by the tracks (now Highway 20).

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] |
Peace River Arch
Peace is a concept of societal friendship and harmony in the absence of hostility and violence. In a social sense, peace is commonly used to mean a lack of conflict (such as war) and freedom from fear of violence between individuals or groups. Throughout history, leaders have used peacemaking and diplomacy to establish a type of behavioral restraint that has resulted in the establishment of regional peace or economic growth through various forms of agreements or peace treaties. Such behavioral restraint has often resulted in the reduced conflict, greater economic interactivity, and consequently substantial prosperity. "Psychological peace" (such as peaceful thinking and emotions) is perhaps less well defined, yet often a necessary precursor to establishing "behavioural peace." Peaceful behaviour sometimes results from a "peaceful inner disposition." Some have expressed the belief that peace can be initiated with a certain quality of inner tranquility that does not depend upo ...

Pembina Oil Field
The Pembina oil field is one of the largest and most prolific conventional oil fields in the province of Alberta, Canada. The mature field is centered on Drayton Valley and is named for the Pembina River, which crosses the region from southwest to northeast. It taps reservoirs in the Cretaceous formations of the Western Canada Sedimentary Basin for oil and gas production. The main hydrocarbon-bearing unit is the Cardium Formation. Production also comes from the Viking Formation and sandstone beds of the Fernie Formation such as the Rock Creek Member. History The first oil was discovered by Mobil Oil in February 1953, and it started a boom that saw the investment of $900 million in the area.

Petroleum
Petroleum, also known as crude oil, or simply oil, is a naturally occurring yellowish-black liquid mixture of mainly hydrocarbons, and is found in geological formations. The name ''petroleum'' covers both naturally occurring unprocessed crude oil and petroleum products that consist of refined crude oil. A fossil fuel, petroleum is formed when large quantities of dead organisms, mostly zooplankton and algae, are buried underneath sedimentary rock and subjected to both prolonged heat and pressure. Petroleum is primarily recovered by oil drilling. Drilling is carried out after studies of structural geology, sedimentary basin analysis, and reservoir characterisation. Recent developments in technologies have also led to exploitation of other unconventional reserves such as oil sands and oil shale. Once extracted, oil is refined and separated, most easily by distillation, into innumerable products for direct use or use in manufacturing. Products include fuels such as gasol ...

Reef
A reef is a ridge or shoal of rock, coral or similar relatively stable material, lying beneath the surface of a natural body of water. Many reefs result from natural, abiotic processes— deposition of sand, wave erosion planing down rock outcrops, etc.—but there are also reefs such as the coral reefs of tropical waters formed by biotic processes dominated by corals and coralline algae, and artificial reefs such as shipwrecks and other anthropogenic underwater structures may occur intentionally or as the result of an accident, and sometimes have a designed role in enhancing the physical complexity of featureless sand bottoms, to attract a more diverse assemblage of organisms. Reefs are often quite near to the surface, but not all definitions require this. Earth's largest coral reef system is the Great Barrier Reef in Australia, at a length of over . Biotic There is a variety of biotic reef types, including oyster reefs and sponge reefs, but the most massive and widely ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anhydrite
Anhydrite, or anhydrous calcium sulfate, is a mineral with the chemical formula CaSO4. It is in the orthorhombic crystal system, with three directions of perfect cleavage parallel to the three planes of symmetry. It is not isomorphous with the orthorhombic barium ( baryte) and strontium ( celestine) sulfates, as might be expected from the chemical formulas. Distinctly developed crystals are somewhat rare, the mineral usually presenting the form of cleavage masses. The Mohs hardness is 3.5, and the specific gravity is 2.9. The color is white, sometimes greyish, bluish, or purple. On the best developed of the three cleavages, the lustre is pearly; on other surfaces it is glassy. When exposed to water, anhydrite readily transforms to the more commonly occurring gypsum, (CaSO4·2H2O) by the absorption of water. This transformation is reversible, with gypsum or calcium sulfate hemihydrate forming anhydrite by heating to around under normal atmospheric conditions. Anhydrite is comm ...
