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 ...
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 ...
"Neotectonics is the study of young tectonic events which have occurred or are still occurring in a given region after its orogeny or after its last significant tectonic set-up [...] The tectonic events are recent enough to permit a detailed analysis by differentiated and specific methods, while their results are directly compatible with ...
Plate tectonics (from Latin tectonicus, from Ancient Greek τεκτονικός (tektonikós) 'pertaining to building') is the scientific theory that Earth's lithosphere comprises a number of large tectonic plates, which have been slowly moving since 3–4 billion years ago.
Structural basin: a syncline-like depression; a region of tectonic downwarping as a result of isostasy (the Hawaiian Trough is an example) or subduction (such as the Chilean Central Valley). Graben or rift valley: fallen and typically linear depressions or basins created by rifting in a region under tensional tectonic forces.
A tectonic window, or fenster (lit. "window" in German), is a geologic structure formed by erosion or normal faulting on a thrust system. In such a system the rock mass (hanging wall block) that has been transported by movement along the thrust is called a nappe.
Geologic tension is also found in the tectonic regions of divergent boundaries. Here, a magma chamber forms underneath oceanic crust and causes sea-floor spreading in the creation of new oceanic crust. [3] Some of the force that pushes the two plates apart is due to ridge push force of the magma chamber. [4]
Slab pull is a geophysical mechanism whereby the cooling and subsequent densifying of a subducting tectonic plate produces a downward force along the rest of the plate. In 1975 Forsyth and Uyeda used the inverse theory method to show that, of the many forces likely to be driving plate motion, slab pull was the strongest. [1]
