Basin evolution model for the Apt Basin before its hydrological connection with the Forcalquier Basin for (a) the Ypresian (?) − Lutetian lacustrine phase, (b) the Bartonian (?) −Priabonian lacustrine phase, (c) the base of the lower Rupelian phase, and (d) the later part of the lower Rupelian phase. Location of main sections displayed on subfigure d (see Fig. 6a for caption). The Coquillade Limestones and Doa Formation are the new lithostratigraphic names introduced in Section 5.2 for the Eocene red limestones and Eocene-lowermost Oligocene (?) siliciclastic deposits. Light green color indicates areas of fluvio-lacustrine deposition, dark green color indicates area of alluvial fan deposition, intermediate green color indicates emerged areas without deposition.
