Resumo

This contribution reports an archaeomagnetic study carried out on burnt samples from the hut 1 of El Cerro de San Vicente (Salamanca). This is an archaeological site dated by relative methods around the end of Iron Age I, a problematic period to apply radiocarbon dating. In order to assess its suitability for archaeomagnetic dating, various samples were collected for directional, magnetic properties and absolute archaeointensity analyses. Samples from the central hearth showed a stable and reproducible NRM behaviour, yielding a mean direction (D = 15.1°; I = 52.5°; k = 477.1; α95 = 5.6°). Abso- lute archaeointensity experiments were performed comparing Thellier-Coe (Thellier and Thellier 1959; Coe et al., 1978) and multispecimen methods. Values of 72.7 ± 4.3 μT (central hearth) and 48.2 ± 2.0 μT (slag samples) were obtained. The archaeomagnetic dating using the SHA.DIF.4k model (Pavón-Carrasco et al., 2021) and archaeologically most plausible, resulted in ca. VII-VI centuries BCE. We associate these high intensity values with the Levantine Iron Age anomaly.
