Europe’s supply of critical raw materials depends on finding them in its own geology. In this two-year research program, fully funded by the TDS group and run with the earth sciences department of a leading Italian university, AuroraTech investigates carbonate rocks enriched in critical metals along fault zones of the Peri-Tyrrhenian area on both sides of the Italian–French border. The work combines structural and geological mapping of the fault systems, sampling and laboratory characterization of the mineralized carbonates, and the geophysical and geochemical signatures that would allow similar bodies to be recognized elsewhere, with the aim of a transferable exploration model for fault-hosted critical-metal carbonates in southern Europe.
