Upward continuation of total magnetic field intensity data over Sokoto basin, north-western Nigeria

High-resolution aeromagnetic data covering the Sokoto basin, north-western Nigeria were acquired and analyzed using regional enhancement techniques, upward continuation second order regional. The objective was to delineate major geological structures. data, which are in form of a grid, knitted Oasis Montaj software obtain magnetic total field intensity map. composite grid reduced equator align peaks anomalies over center their causative bodies. continued at various planes observation understate due shallow features. 10 km, 20 30 40 50 70 100 km above surface. Upward maps produced greatly enhanced long-wavelength (low wavenumber) associated with deeper subsurface revealed high anomaly western parts area low eastern parts. part is interpreted as sedimentary deposit. residual removed from second-order least square method get field. analysis agrees result.
