Figure 7

Sedimentary facies and ferruginous deposits observed in (a) the Sarah paleovalley at S5SA. (b) Ferruginous surfaces at the base of the paleovalley are present in a localized area and cover (c) a large spherical shape, possibly dropstone. (d) Undeformed and parallel layers of sandstone with millimeter-scale ferruginous (Fe) concretions. (e–h) Defamed ferruginous layers in very coarse-grained sandstones and diamictites. (i) A ferruginous pipe was found in the diamictites facies of S5SA.
