Abstract

This study presents the potential of multi-frequency electromagnetic induction (EMI) in archaeology. EMI is currently less employed for archaeological prospection respect to other geophysical techniques. It is capable of identifying shallow subsurface relics by simultaneously measuring the apparent electrical conductivity (ECa) and apparent magnetic susceptibility (MSa). Moreover, frequency sounding is able to quantify the depths and vertical shapes of buried structures. In this study, EMI surveys with five frequencies were performed in two heritage sites with different geological conditions: Han Hangu Pass characterized cinnamon soil, and Xishan Yang by sandy loams. In the first site high ECa values were observed with variations in depth correlated to archaeological remains. Moreover, electromagnetic anomalies related to an ancient road and five kiln caves were identified. In the second site an ancient tomb, indicating extremely low ECa and high MSa, was discovered. Its electromagnetic properties is attributed to the cavity and ferroferric oxides
