Review of the Pilbara Craton and Fortescue Basin, Western Australia: crustal evolution providing environments for early life
AH Hickman - Island Arc, 2012 - Wiley Online Library
The oldest part of the Pilbara Craton is 3.80–3.55 Ga crust. Between 3.53 and 3.22 Ga,
mantle plume activity resulted in eight successive volcanic cycles forming the Pilbara …
