Resumen
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.
