Magnetoestratigrafía y origen de la remanencia del Triásico en la Cordillera Ibérica

Abstract

Detailed palaeomagnetic sampling has been made of two units of the Middle Triassic in the western Cordillera Ibérica in Central Spain. Thermal demagnetization reveals the preservation of characteristic Triassic remanence. A recent overprint is also present, but it is almost completely removed after 5000 C. A magnetostratigraphic section was constructed based upon the isolated stab/e components related to the higher unblocking temperature
