Figure 1. Regional geological sketch map of the Betic-Rif orogen indicating major geological features in the Alboran Basin (simplified from Comas et al., 1997), and location of ODP Leg 161 sites. A conjugate set of strike-slip fault systems marked in black lines crosses the entire basin. EAB = Eastern Alboran Basin; SAB = South Alboran Basin; SBB = South Balearic Basin; WAB = Western Alboran Basin; YB = Yusuf Basin. Box marked with grey line is the area in Figure 2.
