| Popis: | This paper presents an integrated geophysical and geochemical data exploration for assessing the potential presence of gold in Lokoja Sheet 247, Ajaokuta L.G.A of Kogi State, Nigeria by using interpretation of varying derivatives to delineate structural features, with a specific focus on the NE – SW direction, aligning with the regional trend. Additionally, x-ray fluorescence analysis was employed to examine samples from the study area. The interpreted aeromagnetic data unveiled a high anomalous area, prompting further geochemical investigation. X-ray fluorescence analysis indicated gold concentrations ranging up to five parts per million in certain samples, signifying potential high-grade gold mineralization in the study area. Based on the integrated geophysical and geochemical findings, it is recommended that more detailed exploration efforts be concentrated in the eastern half and northwestern portion of the study area. Notably, this research utilized x-ray fluorescence analysis, which proved effective at this stage; however, for more robust information, future exploration endeavors should incorporate advanced geochemical analyses. Moreover, follow-up ground geophysical surveys, including Induced Polarization, ground magnetic, and electromagnetic methods, are deemed necessary. |
