Previous palaeomagnetic studies performed in the Western Interna/ Subbetics revealed the presence of a widespread neogene remagnetizalion in these units. In this work we analyze the hypothesis of a thermoviscous remagnetization to explain this phenomena. We use the palaeomagnetic data to obtain palaeotemperature information. Experiments about viscous and thermoviscous magnetization have been carried out to determine the adequate thermal activation of magnetization theory. This theory estimates palaeotemperature va/ues of about 250ºC far the jurassic limestones of the Western Subbetics.
