Many mineral deposits lie under thick accumulations of post-mineral cover, making exploration expensive and risky. Exploration targeting is thus often focussed mainly on various combinations of gravity and magnetic anomalies. In the case of IOCG styl

Iron oxide–Cu–Au (IOCG) deposits encompass a range of ore body shapes, including strata-bound replacement ores and hydrothermal breccias. We use the implicit method to make a detailed three-dimensional geological model of a strata-bound IOCG in t

The Mt Isa–McArthur region is renowned for a range of commodities and deposit types of world-class proportions. The region is described here in the context of a ‘mineral system,’ through consideration of processes that operate across a range of

The Late Archean Sunrise Dam gold deposit (~10 Moz) is hosted within greenschist-facies rocks and is characterized by extreme structural complexity, resulting from a protracted deformation history with evidence of structural reactivation and multiple

article i nfo Extreme heat flow of 750 mW/m 2 recorded in the central Taupo Volcanic Zone (TVZ) is manifest mostly by convective upwelling of meteoric water in a very hot, thin rift. Despite the very high local heat fluxes and episodic normal faultin

Deformation and focused fluid flow within a mineralized system are critical in the genesis of hydrothermal ore deposits. Dilation and integrated fluid flux due to coupled deformation and fluid flow in simple strike–slip fault geometries were examin

Numerical modelling using a discrete element technique is employed here to examine the response of a fracture system in the eastern Mount Isa Inlier to an applied stress regime. Model scale, parameters and boundary conditions were varied to test whic

The migration of basinal brines into basement material has been proposed as a means of scouring or leaching metals for subsequent ore deposition. Here we address this issue by numerically examining competing processes, namely deformation, fluid flow

The mechanical feasibility of focusing both surface- and basinal-derived fluids towards sites of iron ore genesis during Proterozoic deformation in the Hamersley Province is tested here by computer simulation. Finite difference modelling of porous me

Numerical modelling of deformation and fluid flow on a regional scale was utilised to test recent models for deep (≥ 5 km)penetration of surface fluids involved in genesis of Whaleback style microplaty hematite ores in the Pilbara, Western Australi
