Description:
In this work, we present 16 directional and 27 intensity high-quality values from Iberia.
Moreover, we have updated the Iberian archeomagnetic catalogue published more than 10 years ago
with a considerable increase in the database. This has led to a notable improvement of both temporal and
spatial data distribution. A full vector paleosecular variation curve from 1000 BC to 1900 AD has been
developed using high-quality data within a radius of 900 km from Madrid. A hierarchical bootstrap method
has been followed for the computation of the curves. The most remarkable feature of the new curves is a
notable intensity maximum of about 80 μT around 600 BC, which has not been previously reported for the
Iberian Peninsula. We have also analyzed the evolution of the paleofield in Europe for the last three
thousand years and conclude that the high maximum intensity values observed around 600 BC in the
Iberian Peninsula could respond to the same feature as the Levantine Iron Age Anomaly, after travelling
westward through Europe.
