*3.2.3 Interpretation of data results*

From **Table 12**, it was found that the range of formations thicknesses (minimum to maximum) varying along the profile direction AA' (**Figure 16**), as follows:


**Table 12.**

*Humble salt dome and theoretical calculation parameters for model (2).*


#### **Table 13.**

*The thickness of formations along profile AA' in kilometers (*H *= Σh(*i*),* i *= 1, 2, 3, 4, and 5), humble salt dome.*

**Figure 16.** *The resulted inversion formation' thicknesses along profile AA' of bouguer map (Figure 13).*

**Figure 17.** *The resulted inversion basement rock along profile AA' of bouguer map (Figure 13).*


From **Table 13**, the basement depth along the profile line AA' (**Figure 9**), was determined as follows:

The maximum value of average depth (last column in **Table 13**), equal to 4.70952 km, corresponds to the Bouguer anomaly value of about 22.437979 m. Gal (near the center of Salt Dome anomaly), and the minimum value of the last column, equal to 2.06245 km, corresponds to the Bouguer anomaly value of about 9.826328 m. Gal (near the edges of bounded the Salt Dom anomaly). Therefore, the average depth to the center of the Humble Salt Dome is about 3.386 km, corresponds to the Bouguer anomaly of about 16.128 m. Gal.

The Humble Salt Dome depth of value about 4.71 km is obtained by proposed method, that was agrees very well with the results obtained from drilling, seismic information (4.97 km; after [27]), and a simple method of depth determination by using shape factor (4.85 km; after [21]).
