WMS This web map service provides visualisations of the datasets used as inputs into the analysis of potential for tholeiitic intrusion-hosted Ni-Cu-PGE sulfide deposits in Australia, and the resulting outputs. The datasets included in this service cover the four mineral system components incorporated in the conceptual model for the formation of tholeiitic intrusion-hosted Ni-Cu-PGE sulfide deposits: (1) energy sources or drivers of the ore-forming system; (2) crustal and mantle lithospheric architecture; (3) sources of ore constituents (i.e., Ni, PGE, Cu, S in magmatic systems); and (4) gradients in ore depositional physico-chemical parameters. The results of the analysis are published in the report 'Potential for intrusion-hosted Ni-Cu-PGE sulfide deposits in Australia: A continental-scale analysis of mineral system prospectivity. http://dx.doi.org/10.11636/Record.2016.001'.
