The qualitative interpretation of anomalies of the gravity and the magnetic fields at the west of Tikrit City and surroundings, Iraq, was carried out. According to the tectonic framework of Iraq, the study area is classified as a part of the stable shelf unit. The polynomial technique was employed to separate the residual-regional anomalies as a first step in the qualitative interpretation.
