Fig. 12. In-situ soft-sediment deformation and sandy gravity flows are the main mechanisms forming the Weissliegend facies. Mass flows transport material into interdune areas (A) and create a more symmetrical topography, with the Weissliegend facies thinner on the dune crests and thicker

Economic mineralization also occurs locally where no black shale has been deposited at all, for example, above Weissliegend sand dunes at the basin margin of the Kupferschiefer Sea that were never covered by the black euxinic mud.

On both horizons, the mineralogical change passing upward corresponds to increasing copper depletion. Considering the impermeability of the horizons and the low...
