The Pilbara (/ ˈ p ɪ l b ər ə /) is a large, dry, sparsely populated region in the north of Western Australia. It is known for its Aboriginal people; its ancient landscapes; the prevailing red earth; and its vast mineral deposits, in particular iron ore. It is also a global biodiversity hotspot for subterranean fauna. [1]
The Pilbara shrublands is bounded on the north by the Indian Ocean, and on the west, south, and east by other deserts and xeric shrubland ecoregions - the Carnarvon xeric shrublands to the west, the Western Australian mulga shrublands to the south, and the Great Sandy-Tanami desert to the east and northeast.
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 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]

The Pilbara Craton, which underlies the Hamersley Range, dates back to around 3.4 billion years, but the range itself is younger than that. The deformation that began uplift of the region and created the tightly folded rocks of the range began around 2.2 billion years ago, during the Ophthalmia Orogeny.
