Abstract
An archaeomagnetic study in the archaeological site of El Castillón in Santa Eulalia de Tábara, Zamora (Spain) has been carried out studying samples from four ovens, two bricks and a tile. These structures have been dated from between 5th and 7th centuries A.D. New information for that period is really valuable because of the scarcity of data for Iberian Peninsula between 5th and 10th centuries. The study consisted of thermal demagnetization of 51 specimens, including anisotropy corrections and rock magnetism measures. Two directional and three intensity values were obtained: at the end of 5th century the intensity was 53.7 ± 5.6 μT; at the beginning of 6th century the intensity was 52.0 ± 6.94 μT and the direction was D = 2.7º, I = 59.5º (k=209.2; α95=6.4º); fi nally, in the 7th century the intensity was higher, 61.1 ± 3.1 μT, and the direction D = –7.2º, I = 63.5º (k=1926.2; α95=5.7º). These results have been compared with previous databases and Palaeosecular Variation Curves for Iberian Peninsula and Western Europe. For Iberian Peninsula, the new data are consistent, but for Western Europe the secondary relative maximum around 600 A.D. is not observed in the present study. This fact may mean that there is an error in the dates for the structures analysed in this study or in the French study which shows that maximum.
