For highlighting the potential of gravity method in predicting subsurface geology, the experimentation was done in Sur area lying between Qalahat and Al Kamel in Sultanate of Oman. The area spreads over 1000 sq.kms (50x20 km) and comprises rocks of varied lithology and density. Since the gravity technique is based on lateral density contrasts, it was expected that varied lithostructures of the area will generate sharp to mild density contrasts. Hence, the gravity data were collected along four north-south lines and one east-west oriented orthogonal line from Sur to Al Kamel. The Bouguer anomaly gravity map prepared from the collected data reveals interesting patterns of gravity distribution. shows a gravity decreasing trend towards southwest, and suggests the thickening of sediments. The gravity modeling of all the five lines in combination exposes the presence of four basins (Sur basin, Abat basin, Tahwah basin and AlKamel basin) from northeast to southwest. The thickness of sediments in Abat basin is roughly 2 km, whereas in other basins it is more than 4 km. Abat basin is a pop-up structure controlled by two reverse faults, i.e Jaalan fault and the Qalahat fault. Miocene compressional deformations observed in Sur area are responsible for this positive inversion of Tertiary Abat basin to a pop-up structure.
