Pilbara Craton

From Simple English Wikipedia, the free encyclopedia
(Redirected from Pilbara craton)

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.
