In the historic period, Cuddie Springs was known to both Aboriginal and European people as a palaeontological site. A Dreaming story about Mullyan the eaglehawk is associated to the formation of the bone deposits at the site and the formation of the Macquarie Marshes to the south and the site is also part of a Dreaming track tied to the Macquarie Marshes and the Geera waterhole on the Barwon ...
Rare earths are contained in secondary phosphates and aluminophosphates, presumably derived from weathering of the Proterozoic Mount Weld carbonatite. [4] The primary commercial interest at the site is targeted towards oxides as well as further niobium and tantalum deposits within the intrusive pipe of the Mount Weld carbonatite, which is approximately three kilometers (1.9 mi) in diameter.
Quartz-pebble metaconglomerate (Jack Hills Quartzite), the rock type that contains Earth's oldest dated mineral grains (detrital zircon) Detrital zircons with ages greater than 4 billion years old have been found in these rocks, and a 4,404 ± 8 million year old zircon was found at Erawandoo Hill; [4] this is the oldest dated material originating on Earth; the date is in the Cryptic era of the ...
Metasomatic effects include re-equilibrating isotopic systematics of the lead-zinc sulfides and wall-rocks, and introduction of rare elements into the sulfide bodies to form one of the most diverse mineralogical assemblages in the Earth's crust, with 1500 or more mineral species recognized at Broken Hill, including several dozen not reported ...
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]
[2] [3] Rare earth minerals are rare because rare earth elements have unique geochemical properties that prevent them from easily forming minerals, [4] and are therefore not normally found in deposits large or concentrated enough for mining. [4] This is the reason they are called "rare" earths.

The rare-earth elements (REE), also called the rare-earth metals or rare earths, and sometimes the lanthanides or lanthanoids (although scandium and yttrium, which do not belong to this series, are usually included as rare earths), [1] are a set of 17 nearly indistinguishable lustrous silvery-white soft heavy metals. Compounds containing rare ...
