El paleomagnetismo como indicador de paleotemperaturas. Aplicación a las Cordilleras Béticas

Sumario:Previous palaeomagnetic studies performed in the Western Internal Subbetics revealed the presence of a widespread neogene remagnetization 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 values of about 250°C for the jurassic limestones of the Western Subbetics.
