Delineation of the Acemhöyük settlement mound in Turkey using 2-D and pseudo-3-D VLF imaging

In this study, we aimed to determine the boundaries, locations, and depths of some buried archaeological remains of service buildings belonging to Hatipler Palace in Acemhöyük Settlement Mound from the Assyrian Trade Colony Period (2000–1750 BC) using the very low frequency (VLF) method. After geophysical VLF measurements of the mound, the VLF tipper data were filtered, as is common practice, by Karous and Hjelt (K&H) and Fraser filters. The 2-D VLF inversion technique was also applied to the data, which is a relatively modern procedure for VLF. The 2-D resistivity models obtained after the inversion enabled the construction of 2-D and pseudo-3-D subsurface resistivity images. These imaging techniques revealed two main distinguishing zones of mud-brick walls and stone foundations (moderate resistive zones > 13-Ω m) and surrounding materials (relatively low resistivity zones
