(a) Sedimentary logs in Goult and the Murs Graben. Color coding for sedimentary facies and facies associations displayed on Figure 7. The stage-IV caliche that can be found close to the top of the siliciclastic deposits at both sections is highlighted with a red dashed line. (b) Alternations of facies Fmr (in red) and Spi (in white) in Goult; trees for scale. (c) bed of clast-supported conglomerates of facies Gt with erosive, channelizing base and large trough cross-beddings. (d) Caliche developed in massive, clast-supported conglomerates with normal grading in Murs (facies Gmc).
