Earth’s Magnetic Field: Recent Discoveries from Archaeology and Its Use as a Dating Tool

The geomagnetic field, one of the most enigmatic phenomena in Earth Sciences, is constantly changing. Our knowledge about it in periods prior to instrumental recording is based on geological and archaeological materials, the latter provide the highest resolution for the last 10,000 years. In this talk we will demonstrate how archaeology helps to better understand the geomagnetic field, including the discovery of the “Levantine Iron Age geomagnetic Anomaly” (LIAA), and how in turn our information on regional changes in the field helps to develop an efficient dating tool for archaeology.
