That's Crouton
A craton (/ˈkreɪtɒn/, /ˈkrætɒn/, or /ˈkreɪtən/;[1][2][3] from Greek: κράτος kratos "strength") is an old and stable part of the continental lithosphere. Having often survived cycles of merging and rifting of continents, cratons are generally found in the interiors of tectonic plates. They are characteristically composed of ancient crystalline basement rock, which may be covered by younger sedimentary rock. They have a thick crust and deep lithospheric roots that extend as much as several hundred kilometres into the Earth's mantle.
The term craton is used to distinguish the stable portion of the continental crust from regions that are more geologically active and unstable. Cratons can be described as shields, in which the basement rock crops out at the surface, and platforms, in which the basement is overlaid by sediments and sedimentary rock.
The word craton was first proposed by the Austrian geologist Leopold Kober in 1921 as Kratogen, referring to stable continental platforms, and orogen as a term for mountain or orogenic belts. Later authors shortened the former term to kraton and then to craton.
Examples of cratons are the Slave Craton in Canada, the Wyoming Craton in the United States, the Amazonia Craton in South America, the Kaapvaal Craton in South Africa, and the Gawler Craton in South Australia.
Nothing made me happy today! But I was happy yesterday when I got a strange Mite out of my skin that has been in there since 2011 It Hurt Pulling it out though!
