processing magnetic data. During this project work an aeromagnetic map was digitized, pr-ofiles
were extracted from the digitized map after which I carried out reduction to the poles and
filtering. Finally the approximation
to the depth, amplitude and wavelength of the seleeted
profiles were estimated using computer programs.
This work validates previous works done on the area that shows that the area is a
sedimentary region and contains subsurface deposits that are of economic importance.
