Re-interpretation of Geophysical Data for the Archaeological Hill “Malta” at Duhok City – Iraqi Kurdistan Region

Two geophysical methods (gravity and resistivity) are used to investigate the Malta archaeological
hill in Duhok City-Iraqi Kurdistan Region. 200 gravity observation points were occupied covering
the southern half of the flat-top of the hill. Precise Bouguer anomaly map and its regional, residual
and Second Vertical Derivative anomalies are constructed to show the anomalous remains. High
precision altitudes and accurate positioning of the stations guaranteed reasonable reductions. Beside gravity,
six resistivity traverses are executed along selected directions. A total of 84 Vertical Electrical Sounding
resistivity measurements along traverses were taken to show variations with depth. A final model of the
subsurface was derived by the integration of both geophysical approaches. The two geophysical methods
revealed the presence of wall remains distributed in a systematic manner under the surface. Their
depth ranges from 0.5m to 1.5m. They are mostly built of limestone rocks of high resistivity and
positive gravity anomalies.
