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
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 ]
Unlike the high mountain ranges found in places like the Rockies (highest peak 4,401 m (14,439 ft)), the European Alps (highest peak 4,808 m (15,774 ft)) or the Himalayas (highest peak 8,848 m (29,029 ft)), the Australian Alps were not formed by two continental plates colliding and pushing up the Earth's rocky mantle to form jagged, rocky peaks.
Table Mountain is the northernmost end of a 50-kilometre-long (30 mi) and roughly six-to-ten-kilometre-wide (4 to 6 mi) Cape Fold Mountain range that forms the backbone of the Cape Peninsula, stretching from the Cape of Good Hope in the south to Table Mountain and its flanking Devil's Peak (to the east) and Lion's Head and Signal Hill (to the ...
The Dockyard Shale Formation is an undescribed variegated shale of unknown age that lies buried beneath the Gibraltar's dockyard and coastal protection structures. [ 6 ] Although these geological formations were deposited during the early part of the Jurassic Period some 175–200 million years ago, their current appearance is due to far more ...
The Great Dividing Range, also known as the East Australian Cordillera or the Eastern Highlands, is a cordillera system in eastern Australia consisting of an expansive collection of mountain ranges, plateaus and rolling hills.
The Sandias were uplifted in the last ten million years as part of the formation of the Rio Grande Rift. They form the eastern boundary of the Albuquerque Basin. The core of the range consists of Sandia granite, with a U-Pb age of 1453±12 million years. There is also some metamorphic rock of age 1.60 billion years. [11]
