Abstract
The Curie Point Depth (CPD) estimation of the Eastern sector of Central Nigeria was conducted from the spectral analysis ofresiduals of the total magnetic intensity dataof the eastern sector of central Nigeria. The radially averaged power spectrum of twenty-five blocks of the broadband data were obtained from which differences in frequency characteristics between the magnetic effects from the top and bottom of the magnetized layer in the crust wereidentified. The magnetic effects at the two depths were separated and analysed to determine the Curie depth isotherm. The plots of the spectral energies revealed that the magnetic depths are detectable and the result shows a variation of between 2 and 8.4km in the Curie point depths of the study area. The high prospect areas are found around Atsuku, Takum and Wukari areas in the south-west parts of the study area.
