Craton - Wikipedia
Having often survived cycles of merging and rifting of continents, cratons are generally found in the interiors of tectonic plates; the exceptions occur where geologically recent rifting events have separated cratons and created passive margins along their edges.
Craton - Simple English Wikipedia, the free encyclopedia
A craton is the oldest part of a continental plate. It is an old and stable part of the continental lithosphere. After surviving cycles of merging and rifting of continents, cratons are usually found in the interiors of tectonic plates. They are composed of ancient crystalline basement rock, which may be covered by younger sedimentary rock.
Craton Formation and the Onset of Plate Tectonics
Apr 1, 2018 · Cratons are anomalously-strong regions of the continents that have largely resisted tectonic forces for billions of years. How such strong zones could be forged in a hot, low-viscosity, low stress, early-Earth has been a long-standing puzzle for geologists.
Craton | Structure, Shield, Platform | Britannica
craton, the stable interior portion of a continent characteristically composed of ancient crystalline basement rock. The term craton is used to distinguish such regions from mobile geosynclinal troughs, which are linear belts of sediment accumulations subject …
North China Craton - Wikipedia
The North China Craton is a continental crustal block with one of Earth's most complete and complex records of igneous, sedimentary and metamorphic processes. [1] . It is located in northeast China, Inner Mongolia, the Yellow Sea, and North Korea. [1] .
Cratons, Why Are You Still Here? - Eos
Mar 25, 2021 · Deciphering this evidence reveals information about the origins of plate tectonics, which are closely related to craton formation, as well as about the conditions that favor life on the planet.
Cratons – old and strong - Metageologist - All-geo
Dec 19, 2012 · Cratons are pieces of continents that have been stable for a over a billion years. As earth's plates drift along, mountains periodically rise and fall, plate boundaries appear and disappear.
4.11: Ancient Parts of Continents- Cratons and Shields
Feb 15, 2021 · These ancient shield are part of the stable parts of continents (cratons) and in many places are partially covered by younger sedimentary rocks (such as in the Great Plains and Midwestern Low Plateau regions of North America). Figure 4.34. Formation of Pangaea by closing of the "proto-Atlantic" Iapetus Ocean about 300 million years ago.
Plate tectonics - Wikipedia
Plate tectonics (from Latin tectonicus, from Ancient Greek τεκτονικός (tektonikós) 'pertaining to building') [1] 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.
Creating Continents: Archean Cratons Tell the Story
Continent-continent collisions are a hallmark of modern plate tectonics. These collisional events produce thrust-oriented deformation zones that join terranes of distinctive ages, lithologies, and metamorphic grade.
