The Huraimah fault zone (HFZ) is a conjugate shear zone to the NW-SE-trending Maradi fault zone (MFZ). It is located in the foothills of the Northern Oman Mountains to the east of the Natih and Fahud anticlines, southwest Salakh Arch. Its structural evolution, however, is not well-constraint and rarely documented in previous publications of Northern Oman geology.

This paper presents an in-depth analysis of the structural evolution of the HFZ, using 3-D seismic data, physical analogue models and field data. A 25 x 25 km 3-D seismic survey was analysed firstly to understand the sub-surface geometry of the structure. Then, sand-box models were constructed in a 10 x 90 x 150 cm deformation “rig” to simulate the structure observed in the seismic survey. In addition, field works were done to check the validity of the remote sensing interpretation of the satellite images of the surface exposure of the Huraimah fault zone.
