Forging Earth’s Hotspots: Proterozoic melts that powered giant ore systems

Go to Paper

  • Pb isotopes link Curnamona Province and Gawler Craton magmas to a common source—tying together the Olympic Dam and Broken Hill deposits.
  • Heat-producing elements (U, Th, K) fueled a positive feedback loop of melting, forming a long-lived chemical hotspot.
  • Thick crust from Nuna’s assembly trapped heat, enabling extreme fractionation and metal enrichment over millions of years.
