The present study deals with the geophysical processing and transformation of the available potential field data in the area to study the extensions of the existing sedimentary ridges and basins and their relations to the operating swells and ridges of the basement, to delineate and establish the workable tectonic deformations of area.
Qualitative and quantitative interpretations have been executed utilizing several methods, not only in space domain but also in frequency domain. Regarding the gravity and magnetic analysis, a lot of transformation and enhancement techniques have been executed. Filtering and emphasizing the near surface (local) anomalies from or at the expense of the deep seated (regional) ones, using five orders polynomial surface and their corresponding residuals, as well as the low pass and high pass filters throughout the moving average and the Laplacian operators.
The effective features and the directional elements in the 3-D topographic shape utilizing the edge enhancement and sun-shading technique was made.
Also, the derivatives (i.e. 1st, 2nd and 3rd ) of the field data and their related complex gradients and analytical signal components have a valuable influence in the quantitative analysis. Moreover, the strike filtering techniques is applied to remove the geologic noises cutting across a feature of interest.
Finally, the tectonic elements and structural map of the study area was constructed.
