(a) Top: present-day NW-SE trending ff’ cross-section (map trace on Fig. 5). The tie points with sections aa’ and cc’ are indicated. This section shows the DNCO emplaced over the Mouthoumet massif. It also shows the Boutine-Roc Traucat inverted rollover, and the segmentation of the DNCO in a series of NE-SW trending fault blocks whose strata truncate downward onto Liassic Marls and Keuper detachments. Bottom: restoration of section ff’ to end of Jurassic showing the thin skinned extension of the supra-salt cover decoupled from basement Cevenole faulting along the Keuper evaporites. The lateral equivalent to the SW of the Terres Noires fold pair (Figs. 5, 10a and 13a, b) is framed in black on both present day and restored sections. (b) Uninterpreted and interpreted ENE-ward field view of the Roc Traucat growth strata (Fig. 5a). Blocks of sub- and supra-salt strata lie along the Keuper and Lias Marls detachment levels. (c) Zooms of the lateral equivalent to the SW of the Terres Noires fold pair (framed in black in (a)), showing the activity of NE-SW oriented normal faults within the DNCO during the Jurassic that is demonstrated with the Terres Noires fold pair study (Sect. 4.9, Figs. 5, 10a and 13a, b).
