West of Sarandí del Yí ShearZone the Río de la Plata Craton is intruded by the Late Paleoproterozoic Florida dyke swarm.[4].
The oldest rocks onEarth are found in the North American craton of Canada.
It is not known fromother nickel sulfide gossans within the Yilgarn Craton, potentially due to many of these existing within areas of laterite cover, deeper regolith development or less favorable rainfall conditions.
The West African Craton.
The Congo craton, covered by the Palaeozoic-to-recent Congo basin, is an ancient Precambrian craton that with four others(the Kaapvaal, Zimbabwe, Tazania, and West African cratons) makes up the modern continent of Africa….
There are many microcontinents that are built of continental crust but do not contain a craton.
The Acasta Gneiss is a tonalite gneiss in the Slave craton in Northwest Territories, Canada.
The prominent ring-like topographic feature, easily seen in satellite images, lies onthe boundary between the Palaeoproterozoic Earaheedy Basin and the Archaean Yilgarn Craton.
The West African Craton(WAC) is one of the five cratons of the Precambrian basement rock of Africa that make up the African Plate, the others being the Kalahari craton, Congo craton, Saharan Metacraton and Tanzania Craton.
The thermal activity was caused byexcessive mantle heat that had built up below the craton, insulated by the lithosphere.
Another model proposes that the upwelling in the Iceland region is driven by lateral temperature gradients between the suboceanic mantle andthe neighbouring Greenland craton and therefore also restricted to the upper 200- 300 km of the mantle.[24] However, this convection mechanism is probably not strong enough under the conditions prevailing in the north Atlantic, with respect to the spreading rate, and it does not offer a simple explanation for the observed geoid anomaly.
Baltica was a late-Proterozoic,early-Palaeozoic continent that now includes the East European craton of northwestern Eurasia.
Some geologists restrict the term'continent' to portions of the crust built around stable Precambrian"shield", typically 1.5 to 3.8 billion years old,called a craton.
For the sake of their study, the team considered the distinctive layers of spherule beds that have been discovered in the Pilbara craton in Australia and the Kaapvaal craton in South Africa.
By this definition, Eastern Europe, India and some other regions could be regarded as continental masses distinct from the rest of Eurasia because they have separate ancient shield areas(i.e. East European craton and Indian craton).
Another model proposes that the upwelling in the Iceland region is driven by lateral temperature gradients between the suboceanic mantle andthe neighbouring Greenland craton and therefore also restricted to the upper 200- 300 km of the mantle.
Baltica was created as an entity not earlier than 1.8 billion years ago. Before this time,the three segments/continents that now compose the East European craton were in different places on the globe.
