spacerProject Details

This project aims to establish a tectono-metallogenic model for an important suite of structurally-hosted gold and gold-polysulphide deposits located in the Adelaide Fold Belt of the Delamerian Orogen in South Australia. By understanding the parameters that controlled the mineralising process and the broad geologic environment in which the mineral system operated a geological framework for continuing mineral exploration will be established in this under explored, but potentially well-endowed mineral province.

The specific research questions addressed by this project are:

  • What was the nature of the hydrothermal system and how did it evolve, including pressure-temperature conditions and composition of the mineralising fluids from source to site of deposition?
  • What were the source(s) of metals in the hydrothermal fluids?
  • What was the timing of mineralising events with respect to other key magmatic, metamorphic and deformational events within the orogen; and following from this,
  • What are the key aspects of the geology and tectonic setting that influenced the metallogenic system?
  • How can this information be used to constrain search models and increase the likelihood of exploration success in the Delamerian Orogen?

By answering these questions both a conceptual framework and a process driven (as opposed to empirically driven) rationale will be provided for continuing mineral exploration in the Delamerian Orogen.
