Figure 13. Tectonic map of the westernmost Mediterranean (Alboran and South Balearic seas). Note that the limits of the Messinian salt diapirs in the South Balearic Basin seem to fit with the inferred anomalous continental or oceanic crust as shown in Figure 14A. A, B, C mark the position of cross-sections in Figure 14. Black circles show location of Leg 161 sites and ODP Site 121 as in Figure 4.
