Map of the Balearic Islands. Sketch map of the Balearic Archipelago (W Mediterranean) and of Mallorca and Menorca islands, showing the current relief and location of sampling sites. Contour lines of +90 and +110 m roughly outline palaeogeography during the main Plio-quaternary sea-level transgressive phases, assuming little or no geological uplift or subsidence.
