Abstract
This map portrays deposits for 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$10 000 are shown as a point. No attempt has been made to indicate the potential of an area. The map displays:
- metallic mineral deposits shown as a symbol indicating the
mineral system type, the relative A$ 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 of Deposits. This table gives the deposit name (where known) and the major–[minor] commodities present. Hard rock metallic and industrial mineral deposits shown on the map generally relate to the Palaeoproterozoic Willyama Supergroup, the Neoproterozoic Adelaide Rift Complex and subsequent deformational and metamorphic events including the Olarian Orogeny and Delamerian Orogeny. Younger cover units are shown as a semi-transparent overlay on the basement units.
