Extensional tectonics is associated with the stretching and thinning of the crust or the lithosphere.This type of tectonics is found at divergent plate boundaries, in continental rifts, during and after a period of continental collision caused by the lateral spreading of the thickened crust formed, at releasing bends in strike-slip faults, in back-arc basins, and on the continental end of ...
The word "tectonic" comes from Ancient Greek: τεκτων, "carpenter, builder" that eventually led to master builder, ἀρχιτέκτων (now architect).First application to modern architecture belongs to Karl Otfried Müller, in Handbuch der Archaologie der Kunst (Handbook of the Archeology of Art, 1830) he defined the art forms that combine art with utility (from utensils to dwellings ...
The Vasquez Rock formations, located in the Sierra Pelona Mountains, were formed by tectonic activity along an offshoot of the San Andreas Fault.. Morphotectonics (from Ancient Greek: μορφή, morphḗ, "form"; [1] and τεκτονικός, tektonikos, "pertaining to building" [2]), or tectonic geomorphology, is a branch of geomorphology that studies how landforms are formed or affected by ...
It is important to know if the tectonic phase was a longer event or if it was local or regional. Tectonic phases can be important events that affected large areas. The Alleghenian orogeny in North America (during the Carboniferous period) for example can be found as an angular unconformity between rock layers in large parts of that continent.
Tectonophysics is concerned with movements in the Earth's crust and deformations over scales from meters to thousands of kilometers. [2] These govern processes on local and regional scales and at structural boundaries, such as the destruction of continental crust (e.g. gravitational instability) and oceanic crust (e.g. subduction), convection in the Earth's mantle (availability of melts), the ...
Deformations are numbered according to their order of formation with the letter D denoting a deformation event. For example, D 1, D 2, D 3. Folds and foliations, because they are formed by deformation events, should correlate with these events. For example, an F 2 fold, with an S 2 axial plane foliation would be the result of a D 2 deformation.
With crustal extension, a series of normal faults which occur in groups, form in close proximity and dipping in opposite directions. [4] As the crust extends it fractures in series of fault planes, some blocks sink down due to gravity, creating long linear valleys or basins also known as grabens, while the blocks remaining up or uplifted produce mountains or ranges, also known as horsts.
Tectonic uplift is the geologic uplift of Earth's surface that is attributed to plate tectonics. While isostatic response is important, an increase in the mean elevation of a region can only occur in response to tectonic processes of crustal thickening (such as mountain building events), changes in the density distribution of the crust and ...
