A craton (/ ˈ k r eɪ t ɒ n / KRAYT-on, / ˈ k r æ t ɒ n / KRAT-on, or / ˈ k r eɪ t ən / KRAY-tən; [1] [2] [3] from Ancient Greek: κράτος kratos "strength") is an old and stable part of the continental lithosphere, which consists of Earth's two topmost layers, the crust and the uppermost mantle.
The volcanic area of this rift covers the surface interface between the Mozambique orogenic fold belt and the Tanzania Craton. [1] A superplume exists beneath the craton. [4] [5] An indirect effect of rift and plume associated volcanism in the Tanzania Craton is the high levels of soil nutrients in Serengeti provided by volcanic ash from Ol ...
The craton is named after the country of Zimbabwe where the majority of the craton is. The rocks of the Zimbabwe Craton are separated from the rocks of the Kaapvaal Craton to the southeast by the 250 kilometres (160 mi) wide Limpopo Belt of granulite facies tectonites. The Limpopo belt formed contemporaneously with the Zimbabwe and Kaapvaal ...
The Kalahari Craton is a craton, an old and stable part of the continental lithosphere, that occupies large portions of South Africa, Botswana, Namibia and Zimbabwe. It consists of two cratons separated by the Limpopo Belt : the larger Kaapvaal Craton to the south and the smaller Zimbabwe Craton to the north.
The Slave Craton drifted for approximately 200 million years before its accretion with the Rae Craton around 2.0–1.8 Ga in the Taltson–Thelon orogeny. [ 15 ] [ 18 ] The orogenic belt accreted smaller exotic terranes before the Slave was eventually subducted eastward under the Rae, resulting in a continental magmatic arc known as the Taltson ...
Cambrian blue clay outcrop at beach of Gulf of Finland in Voka Estonia is part of the East European Craton , with an average continental crust thickness between 40 and 64 kilometers. The crust consolidated during the Svecofennian Orogeny in the late Paleoproterozoic , nearly two billion years ago.
