Planches - Figures:
Figure 5 - A 26 cm sand bed near the base of the section at Combe de la Poya
Figure 6 - A 4 cm sand bed with well-preserved internal cross-stratification from the upper part of the section at Villarnet
Figure 7 - The same bed shown in Fig.5 at a smaller scale
Figure 8 - Feathe-edge sand ripples represent final deposition at the distal end of a traction-load lamina
Figure 9 - View perpendicular to the bedding surface showing the scalloped arrangement of ripple-drift cross-laminae
Figure 10 - A 2 cm fine sand layer overlying a discontinuous, lobate silt bed which has been deformed downward into the underlying clay by compaction and/or remobilization of the unconsolidated sediment
Figure 11 - Penecontemporaneous deformation of a silty-clay bed with 30 cm thick near the base of the section at Combe de la Pouya
Figure 13 - Examples of the various types of simple, complex and drainage varves described in the text
