Demonstration of the Effectiveness of Hand-Digitized Aeromagnetic Data: A Case Study of Naraguta

Robert Bassey Umera*, Peter Odong

This work confirms the effectiveness of hand-digitized aeromagnetic data as shown in different works by the authors. A qualitative and quantitative approach was used to demonstrate the viability of hand-digitized aeromagnetic data. Forward and inverse modelling technique was applied. Results show a NW-NE trending of the anomalous bodies characterized by high and low magnetization. It ranges from -65 nT to 87 nT. The profiles indicate the presence of magnetic anomaly in the study area. Amplitudes of profiles 1-4 show lithological contrasts. Summary of quantitative analysis of the data is presented in results. The modelled depth was multiplied by a factor f=1000 due to the fact that data used was Hand-digitized. New depth obtained ranges from -0.3 km to -1.1 km indicating shallow and deep seated structures. Susceptibility values reveal the presence of diamagnetic rocks and suggested rocks and minerals such as gabbro, quartzite, Diabase, and Peridotite. Profile 2 suggests the presence of intrusive bodies in the area.
