interval of 2 m. Gal (**Figure 7a**). The Abu Roash-1well, after [22], was used for the interesting formations' depths and corresponding densities were summed in **Table 5** and were used for building the two hypothetical models 1 and 2 for the Abu Roash Dome Area, with heterogeneous and homogeneous formations' densities

distributions, as respectively, as shown in **Figures 8** and **9**. For the two models, the theoretical calculations were carried out for thicknesses, averages' vertical densities the averages' vertical densities-contrasts, gravity effect, and calculated thicknesses corresponding to each of the selected five formations, that consists of the Abu Roash Dome area, and were summarized in **Tables 6** and **7**.

A digitizing profile along line AA' was carried out for Bouguer gravity anomaly map for Abu Roash Dome Area (**Figure 7b**), with equal intervals 2.09 km., then saved as Excel's file (AbuRoash\_aa\_slab.xlsx), of two coordinates (x, gB). This file
