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 ]
Orogeny (/ ɒ ˈ r ɒ dʒ ə n i /) is a mountain-building process that takes place at a convergent plate margin when plate motion compresses the margin. An orogenic belt or orogen develops as the compressed plate crumples and is uplifted to form one or more mountain ranges. This involves a series of geological processes collectively called ...
Seamount – Mountain rising from the ocean seafloor that does not reach to the water's surface Shield volcano – Low-profile volcano usually formed almost entirely of fluid lava flows Stratocone – Type of conical volcano composed of layers of lava and tephra Pages displaying short descriptions of redirect targets
Orogenic uplift is the result of tectonic-plate collisions and results in mountain ranges or a more modest uplift over a large region. Perhaps the most extreme form of orogenic uplift is a continental-continental crustal collision. In this process, two continents are sutured together, and large mountain ranges are produced.
As the basin fills up, shallow-water sandstones and continental deposits form. [3] [4] Most of the resulting rocks have little deformation, but near the edge of the mountain chain they can be subject to folding and thrusting. [3] After the basin fills up, continental sediments are deposited on top of the flysch. [4]
[1] [2] The extension results in the thinning and deformation of the upper crust, causing it to fracture and create a series of long parallel normal faults. This results in block faulting, where the blocks of rock between the normal faults either subside, uplift, or tilt. The movement of these blocks results in the alternating valleys and ...

The model of a sub-crustal source is similar to the middle-crustal model. In both cases fluids and metals formed from volcanic and sedimentary products in tectonic processes, but also show differences in the origin of the source and the processes involved. [26] This model is associated with fluid ascent from devolatilization of a subducting ...
