Pilbara Craton

From Simple English Wikipedia, the free encyclopedia

The Pilbara Craton is one of only two unntouched Archaean 3.8–2.7 Ga (billion years ago) crusts identified on the Earth.[1]

The other is the Kaapvaal Craton in South Africa. The youngest rocks are 1.7 Ga old in the historic area assigned to the Craton.[2] Both locations may have once been part of the Vaalbara supercontinent or the continent of Ur.
