Investigation of source-to-sink relationships using the detrital record is frequently reliant on zircon and thus biased toward high-temperature magmatic processes. In contrast, rutile, which grows or recrystallizes under lower-temperature conditions, allows reconstruction of the metamorphic history of source terranes. Here, we present the first rutile double-dating analysis, integrating U-Pb geochronology and (U-Th)/He thermochronology on individual grains to refine provenance understanding. Results from heavy mineral−enriched Neogene siliciclastic sediments of the Murray Basin in southeast Australia fingerprint an exotic central Australian source, implying long-distance multicycle sediment dispersal via intermediate sedimentary basins. Source-to-sink relationships support the billion-year influence of radiating pulses of sediment dispersal across the Australian continent from its denuding core.
