## 2 Geological Setting  
The Betic Cordillera (Figure 1) is one of the mountain ranges surrounding the westernmost Mediterranean (Figure 1a) and, together with the Rif Cordillera, forms the Gibraltar Arc (Figure 1b). It is divided into two main domains separated by the Flysch Unit (Figure 1) [48]. To the north, the South-Iberian Domain is formed by the External Thrust and Fold Belt affected by thin-skinned tectonics, being composed of sediments from the extended continental margin [49; 50; 51]. The Prebetic Zone, currently outcropping better in the east, corresponds to the continental platform [18], while the Subbetic Zone, now \begin{table}

To the south and southeast, the Alboran Domain is mainly formed by three metamorphic complexes distinguished by their stratigraphy, metamorphism, and structural position [52]. From top to bottom, these complexes are the Malaguide Complex; the Alpujarride Complex, including the Ronda Peridotities [53]; and the Nevado-Filabride Complex [18]. The Neogene-Quaternary sediments are located above these domains (Figure 1b).
