Ehagay Nakoda (/ eɪ ˈ h ɑː ɡ eɪ n ə ˈ k oʊ d ə / ay-HAH-gay nə-KOH-də; Stoney Nakoda variants include Ehage Nakoda and Îhage Nakoda IPA: [e'hage, ĩ'hage na'koda] [a]) is a multipeaked massif located immediately south of the town of Canmore just east of the Spray Lakes road in Alberta's Canadian Rockies.
Mountain formation occurs due to a variety of geological processes associated with large-scale movements of the Earth's crust (tectonic plates). [1] Folding , faulting , volcanic activity , igneous intrusion and metamorphism can all be parts of the orogenic process of mountain building. [ 2 ]
Mamelon – Rock formation created by eruption of relatively thick or stiff lava through a narrow vent; Mid-ocean ridge – Basaltic underwater mountain system formed by plate tectonic spreading; Pit crater – Depression formed by a sinking or collapse of the surface lying above a void or empty chamber
Magmatism is one of the main processes responsible for mountain formation. The nature of magmatism depends on the tectonic setting . [ 1 ] For example, andesitic magmatism is associated with the formation of island arcs at convergent plate boundaries while basaltic magmatism is found at mid-ocean ridges during sea-floor spreading at divergent ...
The Tunnel Mountain Formation is present in the front ranges of the Canadian Rockies of western Alberta, and reaches a maximum thickness of about 200 metres (600 ft). It unconformably overlies the Etherington Formation or the Todhunter Formation of the Mississippian Rundle Group, and is conformably overlain by the Late Pennsylvanian Kananaskis Formation.
The Mist Mountain Formation is part of the Kootenay Group, an eastward-thinning wedge of sediments derived from the erosion of newly uplifted mountains to the west.The sediments were transported eastward by river systems and deposited in a variety of fluvial channel, floodplain, swamp, coastal plain and deltaic environments along the western edge of the Western Interior Seaway.
The Cedar Mountain Formation is the name given to a distinctive sedimentary geologic formation in eastern Utah, spanning most of the early and mid-Cretaceous.The formation was named for Cedar Mountain in northern Emery County, Utah, where William Lee Stokes first studied the exposures in 1944.
The Sulphur Mountain Formation was first described as a member of the Spray River Formation by P.S. Warren in 1945, [3] who named it for Sulphur Mountain in Banff National Park. It was later raised to formation status. [1] Its type section is located in the Spray River gorge at the southern end of Sulphur Mountain. [1]
