Abstract
<div>Maps showing the potential for carbonatite-related rare earth element (REE) mineral systems in Australia. Each of the mineral potential maps is a synthesis of three or four component layers. Model 1 integrates three components: sources of metals, energy drivers, and lithospheric architecture. Model 2 integrates four components: sources of metals, energy drivers, lithospheric architecture, and ore deposition. Both models use a hybrid data-driven and knowledge driven methodology to produce the final mineral potential map for the mineral system. An uncertainty map is provided in conjunction with the mineral potential map for Model 2 that represents the availability of data coverage over Australia for the selected combination of input maps. Uncertainty values range between 0 and 1, with higher uncertainty values being located in areas where more input maps are missing data or have unknown values. An assessment criteria table is provided and contains information on the map creation.</div>

Purpose
Maps showing the mineral potential for carbonatite-related rare earth element mineral systems in Australia. Each mineral potential map is a synthesis of different component layers: sources of metals, energy drivers, lithospheric architecture, and ore deposition. One model incorporates the first three component layers and excludes any surficial datasets to focus on targeting under cover. A second model incorporates all four component layers, however includes surficial datasets to map the ore deposition component. A hybrid data- and knowledge-driven approach has been used to weight each of the mappable criteria and integrate them to produce the final mineral potential maps. An uncertainty map is provided in conjunction with the mineral potential map for the second model that represents the availability of data coverage over Australia. An assessment criteria table is provided and contains information on the map creation.

Lineage
<div>A large number of published datasets were individually transformed to summarise our current understanding of the spatial extents of key mineral system mappable criteria. These individual layers were integrated using statistically derived importance weightings combined with expert reliability weightings within a mineral system component framework to produce national-scale mineral potential assessments for Australian carbonatite-related rare earth element mineral systems.</div>
