This study investigates the distribution of potential kimberlitic pipes in the Kafur-Masari-Malumfashi region of northwestern Nigeria from satellite gravity and regional aeromagnetic data beyond the Kafur kimberlite pipe discovered previously. The interpretation indicates the presence of some roughly circular to oval shaped analytical signal anomalies which coincide with locations of concealed kimberlitic pipes. These results confirm the Kafur kimberlite and delineate six other suspected kimberlitic pipes. The integrated 2D model images and the signatures of the anomalies obtained allow us to interpret and confirm the field responses as possible multiple kimberlitic pipe intrusions within the basement. Thus suggesting that the region is a potential kimberlite field and represents targets for follow-up surveys.
