Zircon Fields
Zircon is generally found intermixed with Sapphire on the sapphire fields; the fields near the township of Sapphire are typical of this. One outstanding Zircon field is found in the Northern Territory, here, there is a great deposit of Zircon mixed with Apatite, Mica and Vermiculite. This is the area known loosely as the Harts Range; specifically the Mud Tank Zircon field.
