Measurement of Magnetic Susceptibility on Some Rock Samples in Parts of Kuje Area, Abuja-Nigeria

Abstract

Magnetic Susceptibility values are important in interpreting regional magnetic anomalies and in crustal modeling. In this study, Magnetic Susceptibility has been measured on rock samples from the sedimentary succession of Kuje Area in FCT. Variation of susceptibility for the different samples has been analyzed and confirm in the study. According to the measured susceptibility values based on the selected samples, the minimum susceptibility value for sedimentary rocks was found to be 0 which was the minimum value obtained for Dolomite and the maximum susceptibility value for sedimentary rocks was found to be 1480cgs which was the maximum value obtained for shales. For metamorphic rock, the minimum susceptibility value was found to be 25cgs which was the minimum value obtained for schists and its maximum susceptibility value was found to be 3,000cgs which was the maximum value obtained for slate. Finally, the minimum susceptibility value for igneous rocks was found to be 20cgs which was the minimum value obtained for rhyolite and its maximum susceptibility value was 14500cgs which was the maximum value obtained for basalts
