Abstract

The current study was carried out in the southern part of the old Meroe city in Sudan. A magnetic gradient reconnaissance survey revealed the presence of fairly clear archaeological building structures, with small dipole anomalies in the magnetic image due to the presence of fired-brick buildings. 10 closely spaced (1 m) parallel resistivity imaging sections in profiles selected on the basis of magnetic results were used to confirm the magnetic anomalies and to provide complementary information about the variation of the sandstone anomalies in depth. Resistivity imaging profiles were also used to demonstrate the feasibility and reliability of combining 2D resistivity profiles in a 3D data set for inversion using a 3D resistivity inversion code. Inversion results of the 3D resistivity data set are displayed in form of horizontal slices, vertical slices and a 3D block diagram.
