 The Archaean-Palaeoproterozoic Grunehogna Craton in Dronning Maud Land, East Antarctica, formed the eastern part of the Kalahari Craton for at least a billion years.Grunehogna collided with the rest of East Antarctica during the Mesoproterozoic assembly of the supercontinent Rodinia and the Grenville orogeny.The Neoproterozoic Pan-African orogeny and the assembly of Gondwana/Pannotia produced large shear zones between Grunehogna and Kalahari.
