Evidence of slab tearing on an inherited Mesozoic rift transfer fault in the Betic Cordillera.

ABSTRACT: The Western Mediterranean has undergone complex subduction and collision between the African and Iberian plates, influenced by slab segmentation and melt generation. Despite numerous studies aimed at understanding these connections, the style of subduction remains controversial. Utilizing a compilation of geophysical data and a new map of magmatic suites along the Western Betic Cordillera, along with geochemical and geochronological analyses, this paper presents a 3D reconstruction of a segmented subducting slab beneath the Gibraltar Arc, with a focus on the nature and timing of slab tearing and magmatism. Results suggest that magmatism was coeval with the retreating of subduction and slab tearing along the Antequera Fault Zone, a reactivated Mesozoic rift transfer fault. Slab tearing faci
