20 volcanic and 3 sedimentary sites of upper Miocene age were sampled in the Cabo de Gata region in southeastern Spain. Palaeomagnetic and rockmagnetic investigations yielded useful results in 15 volcanic and 1 sedimentary site. Clockwise and anticlockwise block rotations of adjacent blocks could be observed. The age of these rotations is younger than Tortonian. Deformation in the eastern part of the Betics seems to follow a different pattern than in the central and western part of the Subbetic. This behaviour can be related to the crustal structure in the eastern Betics.
