- Tethys–Atlantic interaction along the Iberia–Africa plate boundary: The Betic–Rif orogenic system
- 1. Introduction
- 2. The Pyrenean orogenic system
- 3. The Betic–Rif orogenic system
- 4. Geological and geophysical key constraints on the kinematic model for the Betic–Rif orogenic system
- 4.1. Large-scale plate reconstructions addressing the Africa–Iberia boundary during the Mesozoic and Cenozoic
- 4.2. Spatial distribution of HP/LT metamorphic complexes related to the Alboran and Algerian basins
- 4.3. Role of the mechanical stratigraphy in separating the external from the internal Betic–Rif units
- 4.4. Timing for the onset of the compressional deformation along the Betic–Rif system
- 5. Betic–Rif kinematic evolution model
- 5.1. Stage 1 — model set-up at the onset of the northern convergence of Africa during Late Cretaceous at ~85Ma
- 5.2. Stage 2 — SE-dipping subduction and related HP/LT metamorphism during middle Eocene at ~47–42Ma
- 5.3. Stage 3 — onset of slab roll-back and exhumation of Ligurian–Tethys HP/LT metamorphic rocks after middle Oligocene at ~30–25Ma
- 5.4. Stage 4 — shift to E-dipping subduction, opening of the Alboran back-arc basin and collision of the orogen during late...
- 5.5. Stage 5 — end of major Alboran extension during the middle Miocene at ~18–16Ma
- 5.6. Stage 6 — tightening of the Betic–Rif orogenic system during the late Miocene after 9–8Ma
- 5.7. Stage 7 — Pliocene–Quaternary evolution of the Betic–Rif orogenic system
- 6. Discussion
- 7. Conclusions
