Alteration/diagenesis studies

Exploration criteria and tools are developed through the characterisation of alteration footprints of mineral system types to assist with area and target selection.

Sandstone petrography, including thin section petrography, scanning electron microscopy of thin sections and rock chips, is compared with sandstone porosity and permeability in order to understand the effect and timing of sandstone diagenesis.

Sandstone alterations associated with intrusions and/or faults are equally important since they may affect the reservoir properties, but may also provide important information about the activity of hydrothermal fluids. Alteration of heavy minerals has been applied to understand the redox conditions during sandstone diagenesis.
