North of the Pilbara looking south at the range. At least two important but differing definitions of "the Pilbara" region exist. Administratively it is one of the nine regions of Western Australia defined by the Regional Development Commissions Act 1993; the term also refers to the Pilbara shrublands bioregion (which differs in extent) under the Interim Biogeographic Regionalisation for ...
The Pilbara Craton is an old and stable part of the continental lithosphere located in the Pilbara region of Western Australia. The Pilbara Craton is one of only two pristine Archaean 3.8–2.7 Ga (billion years ago) crusts identified on the Earth, along with the Kaapvaal Craton in South Africa .

The primary source for Tindale's thesis lies in a single reference to the Kau'arndhäri [a] in a 1914 paper by Daisy Bates, [5] where Bates names it as one of four western Pilbara tribes – the others being the Ngarluma, the Kariera, and the Martuthinira – whose class system, governing marriages, is, she claimed, identical.
North West Cape forms the western end of the Pilbara Coast. According to the ICMRA, the Pilbara Coast ends at Cape Keraudren, a rocky headland that forms the western end of Eighty Mile Beach. Others end it further east at Wallal. [4] Lagoons protected by barrier islands, embayments, river deltas, and rocky headlands are the main coastal features.
The Eastern Pilbara Craton is geologically significant due to its age and the types of lithology found within it. Within the Eastern Pilbara Craton there are 2 distinct lithologic divisions: (1), early Earth crust (3.8–3.53 Ga); (2), intrusive granitic domes along with greenstone belts (3.53–3.23 Ga). [3]
