Abstract
Palaeomagnetic and rock-magnetic studies were carried out on samples from thirteen volcanic and nine sedimentary
sites of Late Miocene to Pliocene age from the Internal Zone of the eastern Betic Cordilleras. After comparing
palaeomagnetic results with the expected Pliocene/Miocene direction, rotated and unrotated areas can be recognized,
rotations being clockwise and counter-clockwise. Some rotations are of great magnitude. Unlike deformation in the
External Betics, Late Miocene to Present block rotations in the Internal Betic Zone are non-systematic, and related to the
movement of faults as local responses to the Late Miocene-Present regional stress field, due to the N140 convergence of
Africa and the Iberian Peninsula.
