Abstract
This map portrays metallic and related industrial mineral deposits with a known commodity endowment (past production and global resources). Sites with a known commodity endowment <A$10,000 are not shown. No attempt is made to indicate the potential of an area. The map displays:
- metallic mineral deposits shown as a symbol indicating the mineral system type, the relative A$ value, dominant commodity and for those deposits with an endowment ≥ A$10 million, a reference number;
- related industrial mineral deposits shown by a symbol indicating the mineral system type, the relative A$ value, dominant commodity and, for those deposits with an endowment ≥ A$10 million, a reference number.
The reference number next to a symbol relates to the Table of Deposits, which gives the deposit name (where known) and the major–(minor) commodities.
Hard rock metallic and industrial mineral deposits shown on the map generally relate to Permian submarine volcanism that resulted in volcanic-associated massive sulfide and epithermal vein mineralisation; the emplacement of late Permian to Middle Triassic fractionated plutons resulting in wide spread Sn–W and Au mineralisation; and structurally controlled Au, Au–Sb and Sb vein systems that formed during the Permian and Triassic (see Geological History on the reverse side of the map).
Younger cover units are shown as a semi-transparent overlay on the basement units. Some of these units host metallic and related industrial mineral deposits that are also shown on this map.
