Evolución tectónica de la Falla de Socovos desde el Mioceno hasta la actualidad
2012
The Socovos fault is the northeastern dextral transfer zone of the Cazorla Arc. With a trace of
more than 80 km and a minimum displacement of 35 km, the fault is one of the better defined structures
within the Betic remains understudied. In fact, the intrusion into the fault zone of several tens of
lamproite dikes, some of them with several kilometers of continuity, has gone unnoticed until our
research. The Fault determines both the style of deformation and the orientation of the structures in each
of the blocks, which are for the same age almost orthogonal. This strain partitioning has not satisfactory
explained by the current tectonic models. Most of the activity of the fault appears to be concentrated in
lower-middle Miocene, although the analysis of successive sedimentary bodies from upper Miocene to
present shows sometimes significant deformations. Moreover, paleomagnetic analysis of volcanic dykes
indicates shear rotations in the fault zone younger than ca. 7 Ma. The Socovos Fault can be considered
currently as a potentially seismic fault.
