dc.description.abstractThe work is aimed at estimating depth to the bottom of a magnetic source (DBMS) using spectral analysis of high-resolution aeromagnetic (HRAM) data over Sokoto Basin in the North Western part of Nigeria. The area is bounded by latitude 10.000 to 14.000N and longitude 3.500 and 7.000E with a total area of 111,925 km2. The HRAM data, acquired from the Nigerian Geological Survey Agency (NGSA), were divided into twenty-two (22) overlapping blocks of the size of, 110 × 110km. In the centroid method of estimating DBMS, two power spectrum plots were plotted for each of the twenty-two overlapping blocks. The high-wavenumber part whose slopes lead to the depth to the top of magnetic sources (Zt) and the low-wavenumber part whose slopes lead to the centroid depth of the magnetic sources (Z0). These depth values were subsequently used to determine, DBMS obtained from Zb = 2Z0 – Zt. The results show a variation in DBMS between 11.13 and 27.83 km with an average of 18.57km. The study is found to have geothermal potential in the northcentral part of the study area owing to shallow values of DBMS.en_US
