Discussion on ‘Spectral analysis of aeromagnetic data for geothermal energy investigation of Ikogosi Warm Spring - Ekiti State, southwestern Nigeria’

Abstract

Background: The recent paper by Abraham et al. (2014) ‘Spectral analysis of aeromagnetic data for geothermal energy investigation of Ikogosi Warm Spring - Ekiti State, southwestern Nigeria’ applied spectral analysis in the interpretation of aeromagnetic data for estimation of curie-point depths using a data window of 55 × 55 km; however, the employment of such small window may not be consistent with derived curie-point depth results. Discussion: Here, I would like to clarify and point out the possible errors in the paper. Summary: It is suggested that the curie-point depth results be re-computed with appropriate window width. This would tremendously assist researchers in appropriate spectral calculation and curie-point depth investigations.
