مستخلص المنشور

A procedure for a dip angle determination of a fault plane from gravity field data is presented to
constrain a seismic profile interpretation. This procedure is applied on Mahjouba normal fault at the
western border of Kalaa Khesba graben (Central Tunisian Atlas Province, North Africa). Seismic and
detailed gravity data, in this region, were analyzed to provide more constraints on the geometry of the
fault dip angle. The Mahjouba fault is mapped as three major parallel lineaments extended for 2 kmwith
a NW-SE to N-S trend. The dip of the Mahjouba fault is estimated from the gravity modeling data to be
45E. This study reveals that integrating gravity and seismic data provides accurate mapping of faults
geometry and such result provides useful information and constraints on the exploration of natural
resources.
