Betic part of the Alboran Domain (Fig. 2 for location). A: Overall map of the Betic Internal Zones, basically made up of the nappe stack formed at the expense of the Alboran Domain basement, strongly thinned during its Miocene eastward extension (after Martín-Algarra et al., 2019). B: Enlarged map of the western Betics showing the Frontal units (Dorsale Calcaire) and peridotites massifs (after Balanyá et al., 1997). C: Longitudinal cross-section (after Platt et al., 2013) emphasizing the westward thrusting and thinning of the nappe stack, which is separated from the External Zones by a major, dextral compressional strike-slip (Iberian-Betic Shear Zone). D: Two stratigraphic columns from the Frontal Units (after Jabaloy Sánchez et al., 2019). See (B) for location. Lithologies: Norian: red pelites, gypsum, dolostones; Rhaetian: alternating dolostones/limestones; Hettangian: dolomitic coarse breccia; Sinemurian-Toarcian: cherty/marly limestones; Middle-Upper Jurassic: cherty/marly limestones, radiolarites; Berriasian to Barremian: varicolored claystones and marls, carbonate breccias, neptunian dykes; Aptian-Albian: sandstones, shales; Campanian-Maastrichtian: varicolored claystones and marls, carbonate microbreccias, fine-grained sandstones.
