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 ...
The Hanging Hills of Connecticut (Metacomet Ridge range); upfaulting visible from right to left. Horizontal movement between blocks along a strike-slip fault. Fault blocks are very large blocks of rock, sometimes hundreds of kilometres in extent, created by tectonic and localized stresses in Earth's crust.
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.
Typical examples include the development of calderas and resurgences, pit craters, dikes, sills, laccoliths, magma chambers, eruptive fissures, volcanic rift zones and any type of volcano flank dynamics, including sector collapses. In the second case, the process controlling the magma may have a regional extent, also outside the volcanic area.
Type locality, also called type area, is the locality where a particular rock type, stratigraphic unit or mineral species is first identified. [1] If the stratigraphic unit in a locality is layered, it is called a stratotype, whereas the standard of reference for unlayered rocks is the type locality.
The Eurasian plate is a tectonic plate that includes most of Eurasia (a landmass consisting of the traditional continents of Asia and Europe), with the notable exceptions of the Arabian Peninsula, the Indian subcontinent, and the area east of the Chersky Range in eastern Siberia.
Solidified lava flow in Hawaii Sedimentary layers in Badlands National Park, South Dakota Metamorphic rock, Nunavut, Canada. Geology (from Ancient Greek γῆ (gê) 'earth' and λoγία () 'study of, discourse') [1] [2] is a branch of natural science concerned with the Earth and other astronomical objects, the rocks of which they are composed, and the processes by which they change over time.
