Qualitative and Quantitative interpretation ofhand-digitized aeromagnetic data from Idah has beencarried out by applying forward and inverse modelingtechnique. Qualitatively, wavelength and amplitudes ofsource bodies reveal lithologic contrast, basementstructure and sedimentary magnetization contrast. Themaximum depth to top of the magnetic source bodyobtained is 16.8m and minimum depth is 0.5m. Theanomalous bodies’ total magnetic intensity ranges from aminimum negative peak value of -153.5nT to maximumvalue of 162.7nT. Susceptibility values obtained reveals thepresence of rocks such as granite, diabase, olivine-diabase,basalt/gabbro, quartzite and diorite. Results obtainedshows that hand-digitized data competes favorably with computer digitized data
