Mount Weld Mine, Mount Weld Station, Laverton Shire, Western Australia, Australia

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
