Abstract

Qualitative and Quantitative Interpretation of Hand-digitized Aeromagnetic Data from Idah

Robert Bassey Umera, Odong Peter

Qualitative and Quantitative interpretation of hand-digitized aeromagnetic data from Idah has been carried out by applying forward and inverse modeling technique. Qualitatively, wavelength and amplitudes of source bodies reveal lithologic contrast, basement structure and sedimentary magnetization contrast. The maximum depth to top of the magnetic source body obtained is 16.8 m and minimum depth is 0.5 m. The anomalous bodies’ total magnetic intensity ranges from a minimum negative peak value of -153.5 nT to maximum value of 162.7 nT. Susceptibility values obtained reveals the presence of rocks such as granite, diabase, olivine-diabase, basalt/gabbro, quartzite and diorite. Results obtained shows that handdigitized data competes favorably with computer digitized data.
