الملخص الإنجليزي

The available data includes a Bouguer anomaly map prepared by the IPC in the fifties with a scale of 1:200000 and contour interval of one mgl .The data also includes a total field aeromagnetic map of Ghada area prepared by the CGG company in 1974 .

The available data also includes the geological successions of the above mentioned wells as well as physical properties of these rocks succession obtained from these wells and previous research on the area.

.

Interpretations have shown that the gravity highs of Swab in Syria and Ghada in Iraq are related to two basic igneous masses that outcrop at the basement surface and are connected at a depth of 12.5km .

Interpretation of the magnetic anomaly over Ghada area has shown the source to be the same igneous mass and has the same properties , dimensions and depth as the gravity source of Ghada .

Two solutions are given for the gravity low (the saddle) between Swab high and Ghada high.

Thick accumulation of U.Cretaceous (low density) caused by block faulting within Anah graben is one solution.

The other is caused by thinner accumulation of these rocks and also by down faulting of the Paleozoic assuming that the graben faults have deep seated origion.

.

The data on thickness distribution of the sedimentary column accumulated for the present study as well as for previous studies are considered sufficient to produce a structure contour map on top of the basement.
