Figure 2. Geologic sketch of the Alboran Sea basin showing the location of main sedimentary depocenters, DSDP Site 121, and Leg 161 sites. Betic Neogene Basins outcrops (mainly Miocene to Pliocene marine sediments) onshore are indicated for Spain. Sedimentary depocenters in the Alboran Sea: 1 = depocenters consisting of lower Miocene to Pleistocene deposits; 2 = depocenters consisting of middle Miocene to Pleistocene deposits; 3 = depocenters consisting of Messinian/Pliocene to Pleistocene deposits. Black triangles = outcrops of lower Miocene marine sediments; white triangles = outcrops of Middle Miocene marine sediments. A = Almeria basin, EAB = Eastern Alboran Basin, GB = Granada Basin, GX = Guadix basin, GH = Guadalhorce basin, R = Ronda basin, S = Sorbas basin, SAB = Southern Alboran Basin, V = Vera basin, and WAB = Western Alboran Basin.
