Multi-frequency EMI in archaeological prospection: case studies of Han Hangu Pass and Xishan Yang in China

Abstract

Among geophysical techniques applied toarchaeological sites , the multi-frequency EMI methodis capable of identifying shallow subsurface relics bysimultaneously measuring the apparent electricalconductivity (ECa) and apparent magneticsusceptibility (MSa).In this study, multi-frequencyEMI technologies were performed in two heritagesites with different geological conditions. In the site ofHan Hangu Pass, high ECa values were measured dueto the cinnamon soil. Variations of ECa from thesurface to shallow subsurface with different depthsindicate a correlation with archaeological excavations.Whereas, electromagnetic anomalies related to anancient road and five kiln caves were identified. In theXishan Yang, sandy loams result into lower ECavalues. An ancient tomb, indicating extremely lowECa and high MSa, was discovered. Itselectromagnetic properties is attributed to the cavityand ferroferric oxides. Afterwards, the depths ofinvestigation (DOI) in conjunction with theperformance of signal frequencies were assessed andanalyzed.
