  2. Diastrophism - Wikipedia

    en.wikipedia.org/wiki/Diastrophism

    Diastrophism is the process of deformation of the Earth's crust which involves folding and faulting. Diastrophism can be considered part of geotectonics. The word is derived from the Greek διαστροϕή diastrophḗ 'distortion, dislocation'. [1]

  3. Detachment fault - Wikipedia

    en.wikipedia.org/wiki/Detachment_fault

    View of Doso Doyabi, Snake Range, Nevada, which was formed by detachment faulting. A detachment fault is a gently dipping normal fault associated with large-scale extensional tectonics . [ 1 ] Detachment faults often have very large displacements (tens of km) and juxtapose unmetamorphosed hanging walls against medium to high-grade metamorphic ...

  4. Epeirogenic movement - Wikipedia

    en.wikipedia.org/wiki/Epeirogenic_movement

    Such plate convergence forms orogenic belts that are characterized by "the folding and faulting of layers of rock, by the intrusion of magma, and by volcanism". [5] [6] Epeirogenic movements may divert rivers and create drainage divides by upwarping of the crust along axes.

  5. Mountain formation - Wikipedia

    en.wikipedia.org/wiki/Mountain_formation

    Illustration of mountains that developed on a fold that thrusted. 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 ...

  6. Detachment fold - Wikipedia

    en.wikipedia.org/wiki/Detachment_fold

    The basic geometries of detachment faulting of a symmetric detachment fold are shown in Figure 4. Refer to Mitra [4] [15] for an evolutionary model of faulted detachment folds in the asymmetric and symmetric settings. Faulting may occur in a symmetric or asymmetric fold, yielding fault geometries that are both alike and dissimilar.

  7. Fold mountains - Wikipedia

    en.wikipedia.org/wiki/Fold_mountains

    Fold mountains form in areas of thrust tectonics, such as where two tectonic plates move towards each other at convergent plate boundary.When plates and the continents riding on them collide or undergo subduction (that is – ride one over another), the accumulated layers of rock may crumple and fold like a tablecloth that is pushed across a table, particularly if there is a mechanically weak ...

  8. Tilted block faulting - Wikipedia

    en.wikipedia.org/wiki/Tilted_block_faulting

    Tilted block faulting, also called rotational block faulting, is a mode of structural evolution in extensional tectonic events, a result of tectonic plates stretching apart. [ 1 ] [ 2 ] When the upper lithospheric crust experiences extensional pressures, the brittle crust fractures, creating detachment faults . [ 3 ]

  9. Décollement - Wikipedia

    en.wikipedia.org/wiki/Décollement

    Two different types of folding may occur at a décollement. Concentric folding is identified by uniform bed thickness throughout the fold, and is necessarily accompanied by detachment or a décollement as part of the deformation that occurs with a thrust fault. [15] Disharmonic folding does not have uniform bed thickness throughout the fold. [16]
