The present study dealt with the geophysical processing and interpretation of the available magnetic data in
the area of study. the extensions of the existing sedimentary ridges and basins and their relations to the operating
swells and ridges of the basement, as well as delineated the workable tectonic deformations of the considered
area. Multi-discipline system of interpretations has been executed utilizing several methods, not only in the
space domain, but also in the frequency domain. Filtering and emphasizing the near-surface (local) anomalies on
the expense of the deep-seated (regional) ones were done, using five orders polynomial surfaces and their
corresponding residuals, as well as the low-pass and high-pass filters through out the moving average operator.
The effective features, and the causative sources, as well as their corresponding depths were delineated through
the first and second derivatives of the field data and their related complex gradients. Also, the strike filtering
technique was applied at specific directional trend and five kms to remove the geologic noises cutting across the
implications of interest through the enhancement and suppression processes .Moreover, the magnetic field was
upwarded and downwarded at consecutive levels to follow the geologic signatures at the five kms. Finally,
integration was done for the results of the fore-mentioned techniques to delineate the structural features and
tectonic inferences characterizing the concerned area. |
