Muskwa Formation

	Muskwa Formation The Muskwa Formation is a stratigraphic unit of Frasnian age in the Western Canadian Sedimentary Basin. It takes the name from Muskwa River, and was first described in the Western National Gas Fort Nelson a-95-J/94-J-10 well by F.F. Gray and J.R. Kassube, in 1963. Lithology The Muskwa Formation is composed of bituminous shale. Pyrite is a common accessory mineral. Gas production Gas is produced from the Muskwa Formation shales in the Horn River Basin in the Greater Sierra oil field in north-eastern British Columbia. Horizontal drilling and fracturing techniques are used to extract the gas from the low permeability shales (see ''Shale gas''). Distribution The Muskwa Formation occurs in northern Alberta, north-eastern British Columbia and in the southern part of the Northwest Territories, and typically has a thickness of . Relationship to other units The Muskwa Formation is a sub-unit of the Horn River Formation; it is conformably overlain by the Fort Simpson Formation and ...

picture info	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 (geology), 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Devonian British Columbia The Devonian ( ) is a geologic period and system of the Paleozoic era during the Phanerozoic eon, spanning 60.3 million years from the end of the preceding Silurian period at million years ago ( Ma), to the beginning of the succeeding Carboniferous period at Ma. It is the fourth period of both the Paleozoic and the Phanerozoic. It is named after Devon, South West England, where rocks from this period were first studied. The first significant evolutionary radiation of life on land occurred during the Devonian, as free- sporing land plants (pteridophytes) began to spread across dry land, forming extensive coal forests which covered the continents. By the middle of the Devonian, several groups of vascular plants had evolved leaves and true roots, and by the end of the period the first seed-bearing plants ( pteridospermatophytes) appeared. This rapid evolution and colonization process, which had begun during the Silurian, is known as the Silurian-Devonian Terrestrial Revolu ...

picture info	Natural Gas Fields In Canada Nature is an inherent character or constitution, particularly of the ecosphere or the universe as a whole. In this general sense nature refers to the laws, elements and phenomena of the physical world, including life. Although humans are part of nature, human activity or humans as a whole are often described as at times at odds, or outright separate and even superior to nature. During the advent of modern scientific method in the last several centuries, nature became the passive reality, organized and moved by divine laws. With the Industrial Revolution, nature increasingly became seen as the part of reality deprived from intentional intervention: it was hence considered as sacred by some traditions (Rousseau, American transcendentalism) or a mere decorum for divine providence or human history (Hegel, Marx). However, a vitalist vision of nature, closer to the pre-Socratic one, got reborn at the same time, especially after Charles Darwin. Within the various uses of the word t ...

picture info	Geologic Formations Of Alberta Geology (). is a branch of natural science concerned with the Earth and other astronomical objects, the rocks of which they are composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology. It is integrated with 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. Geologists study the mineralogical composition of rocks in order to get insight into their history of formation. Geology determines the relative ages of rocks found at a given location; geochemistry (a branch of geology) determines their absolute ages. By combining various petrological, crystallographic, and paleontological tools, geologists are able to chronicle the geological history of the Earth as a whole. One aspect is to demonstrate the age of the Earth. Geology provides evidence for plate tectonics, the evolutionar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

At a land area of approximately and a 2021 census population of 41,070, it is the second-largest and the most populous of Provinces and territories of Canada#Territories, the three territories in Northern Canada. Its estimated population as of the first quarter of 2025 is 45,074.

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. At first, it was named the North-West Territories. The name was changed to the present Northwest Territories in 1906. Since 1870, the territory has been divided four times to create new provinces and territories or enlarge existing ones.

	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 2023, the region had a population of approximately 374,572. Geography Various definitions exist of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
