dc.description.abstractThe Magnetic Intensity data of aeromagnetic survey, as conducted by Nigerian Geological Survey Agency, were acquired from sheets 200 and 201 for qualitative and quantitative interpretation purposes. The area is bounded by latitudes 8.5°N–9.0°N and longitudes 3.5°E–4.5°E covering an area of about 6150.50 km2. The data were reduced off the regional field to obtain the residual field. Upward continuation and analytical signal were employed for qualitative interpretations. In addition to Euler and Werner Deconvolutions, spectral depth analyses were carried out to estimate the depth to causative geologic structures and basement of the target marble deposit. The residual field contour shows an intensity ranging from −63.05 to 52.65 nT, indicating series of magnetic highs and lows. The obtained positive residual anomalies could stand as responses to the outcrops common in the area, while the negative field could be associated with the presence of granitoids and felsic volcanic rocks or major fault zones. The reached result prove to reveal minimum and maximum depths of 1.07 and 3.79 km, suggesting an expected thickness extent of the deposit. Further Depth estimate around the current mining appears to range from 2.0 to 2.2 km.en_US
