Abstract:
We integrate seismic tomographic models and filtered gravity anomaly maps to investigate the compositional variations in the SCLM of Australia. We find zones of relative enrichment and depletion coinciding with the spatial extent of major thermal events. Anomalous regions of enrichment may represent subduction metasomatism of the lithospheric mantle, or refertilisation due to asthenospheric upwelling. Regions of apparent depletion signify high-degree melt extraction from a previously more enriched lithosphere.
