Multichannel seismic data imaging of inversion tectonics of the Alboran Ridge (western Mediterranean Sea)

摘要

The Alboran Ridge is an anticlinorium structure trending N65°E bounded by two main right lateral strikeslip fault systems, one north and one south. These transpressional features connect westward to a pull-apart zone where massive diapirism occurs. The orientation of the diapiric zone is N150°E. That orientation and the right lateral motion along the Alboran Ridge fit a N150°E convergent motion between African and Iberian plates. We suggest that the southern Alboran Basin evolved as an extensional stage from Burdigalian to Langhian and as a transpressional stage during Tortonian to present ti
