Fig. 5.  Late Quaternary sea-level curve (modified from Kershaw & Guo 2006) showing pathways of uplift of the relevant components. The four sloping lines at 0.23 mm a represent the averaged uplift (from Leeder et al. 2005) of the surface on which mounds sit, the MIS 5e terrace top, the proposed MIS 7a/c terraces and the mound near Heraion lighthouse (up to their current positions of at c. +15 m, c. +25 m, proposed c. +40 m and c. +55 m, respectively). Uplift of late Quaternary marine sediments in the Isthmus of Corinth (IC) and two interpretations of the behaviour of the Rion Sill (RS) are shown. The interplay between these two barriers probably created a lake in the Gulf during MIS 6. The inset map shows the locations of IC, RS and the Perachora Peninsula (PP). The significance of the various possible pathways of terrace uplift is discussed in the text.
