Hidden architecture shapes world‑class sediment-hosted mineral systems

The long‑lived Proterozoic sedimentary basins of this region host significant copper and gold resources, and are viewed as an increasingly important domain for exploration. This new study reveals that inherited crustal structures strongly influenced the extension and subsequent inversion of these basins, controlling key aspects of basin geometry, faulting, and fluid pathways while the systems evolved towards increasingly focused rift geometries under elevated heat flow conditions. Geophysical imaging further uncovers deep lithospheric corridors tied to major mineral belts, offering a powerful framework for targeting concealed deposits in future exploration.
