Abstract
This map portrays deposits of a range of commodity types. They include metallic, industrial and selected construction material sites with a known commodity endowment (past production and global resources). Sites with a known commodity endowment
<A$10,000 are shown as a point only. No attempt is made to indicate the potential of an area. The map displays:
- metallic mineral deposits shown as a symbol indicating the mineral system type, the relative A$ value, dominant commodity and a reference number;
- industrial mineral deposits shown by a symbol indicating the mineral system type (where applicable), the relative A$ value, dominant commodity and a reference number; and
- selected construction material sites with commodity type, relative A$ value and a reference number.
The reference number given to each symbol relates to the table next to the map. This table 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 the Ordovician Girilambone Group, late Silurian to Early Devonian Cobar Supergroup, Silurian to Early Devonian granites that intrude both units, and subsequent deformational and metamorphic events including the Tabberabberan Orogeny (see Geological History on the reverse side of the map). Younger cover units are shown as a semi-transparent overlay on the basement units.
