Mount Weld REE deposit; Mount Weld deposit
Carbonatitic REE deposit with additional Nb, Ta, Zr, Ti contents ('Crown deposit' - apparently a separate part of the carbonatite).
Discovered in 1988; owned by Lynas Corp.
Located about 30 km south of Laverton and 120 km east of Leonora.
Rare earths are contained in secondary phosphates and aluminophosphates, presumably derived from weathering of the Proterozoic Mount Weld carbonatite, an intrusive pipe approximately three kilometers in diameter.
One of the references describes churchite as a fragile secondary mineral of microcrystalline acicular radiating crystals. It is found as void filling in crandallite group minerals, and as encrustations on limonite aggregates, weathered magnetite, on crandallite group grains, and sometimes as fine grained intergrowths with limonite
Carbonatite Complex is roughly circular in plan, 4km in diameter and intrudes Archean greenstone sequence consisting essentially of basic and ultrabasic volcanic rocks and metasediments (Duncan & Willett 1990; Middlemost 1990). Carbonatite dikes have been intersected in drilling up to 5 km from the complex, but there is no associated alkaline silicate rock.
Rare earth element (REE) deposit, is one of the largest of its type on Earth. Current mining exploits the high-grade weathered goethite-bearing resource that lies above, and which represents the weathering product of a subjacent carbonatite.

Geochronology
Mineralization age: Paleoproterozoic : 2064 ± 13 MaImportant note: This table is based only on rock and mineral ages recorded on mindat.org for this locality and is not necessarily a complete representation of the geochronology, but does give an indication of possible mineralization events relevant to this locality. As more age information is added this table may expand in the future. A break in the table simply indicates a lack of data entered here, not necessarily a break in the geologic sequence. Grey background entries are from different, related, localities.
