Two magnetisation components could be isolated by thermal cleaning: a secondary syntectonic component of always normal polarity unblocking at intermediate temperatures up to 450 °C/475 °C (A component) and a high temperature unblocking component up to 575 °C (B component). The B component passes fold and reversal tests and is considered the characteristic remanent magnetisation of primary origin. The first Toarcian palaeomagnetic pole for Iberia has been obtained: Plat = 77.4°, Plon = 241.3°E (dm = 5.4° dp = 6.0°). Five pairs of normal and reversed polarity zones were calibrated to regional ammonite subzones. The pattern can be calibrated to other Toarcian magnetostratigraphic studies, but provides a more detailed biostratigraphic framework. A refined magnetic polarity time scale is proposed for the Lower–Middle Toarcian.engjournal article1385-013Xhttps://doi.org/10.1016/j.epsl.2007.04.048restricted access537.6:551.7(460)551.762magnetostratigraphyEarly JurassicbiostratigraphyIberian PlateGeología estratigráfica2507.01 Geomagnetismo y Prospección Magnética2506.19 Estratigrafía
