| The basin is separated from the craton by a major tectonic flexure known as the Redstone arch. |
| A large area of northern and central Canada is underlain by a huge craton, which forms the nucleus of the North American continent. |
| However, this mode of emplacement is contradictory to well-established ideas for Archaean granites in the Zimbabwe craton. |
| These rocks are also of biogeographic interest because unlike truly allochthonous terranes they are parautochthonous with respect to the craton. |
| Much of the craton remained stable up to Triassic time, with sedimentary sequences dominated by shallow-water and subaerial sediments. |
| The currently accepted name for this part of the craton is the Murehwa batholith. |
