What is Alboran Domain Geodynamics?

Alboran Domain Geodynamics studies the crustal thinning, lithospheric delamination, and convective removal driving Miocene extension in the Alboran Sea region between Iberia and North Africa.

Researchers use gravity modeling, receiver function analysis, and petrological studies of volcanic rocks to reconstruct back-arc basin formation. Key processes include subduction rollback and slab segmentation as described by van Hinsbergen et al. (2014, 340 citations) and continental-edge delamination evidenced by Duggen et al. (2005, 525 citations). Over 10 major papers from 1995-2018 analyze these mechanisms.

Key Challenges

Why It Matters

Alboran geodynamics explains back-arc basin formation linked to mantle processes, informing tectonic models for the western Mediterranean. Duggen et al. (2005) connect post-collisional magmatism to lithospheric delamination, revealing uplift mechanisms on Iberian and African margins. Van Hinsbergen et al. (2014) detail subduction rollback and slab segmentation, clarifying Oligocene extension initiation and forearc dispersal. These insights guide seismic hazard assessment in the Gibraltar arc and resource exploration in thinned crust basins.

Key Research Challenges

Reconciling Collision with Extension

Explaining extensional basin formation amid continental collision remains paradoxical. Docherty and Banda (1995, 143 citations) propose delamination via subsidence analysis, but timing conflicts persist. Integrating petrological and geophysical data is needed.

Quantifying Lithospheric Delamination

Distinguishing delamination from convective removal requires precise mantle imaging. Duggen et al. (2005, 525 citations) provide magmatic evidence, yet depth and rate estimates vary. Receiver functions and gravity modeling yield inconsistent slab geometries.

Modeling Subduction Rollback Dynamics

Simulating slab retreat and back-arc extension faces scaling issues in analogue models. Faccenna et al. (1996, 244 citations) experiment on Tyrrhenian opening, analogous to Alboran. Numerical models must incorporate tectonic inheritance per Rollet et al. (2002).
