Abstract

The crustal thickness within the Southern Bida Basin has been determined using Bouguer Gravity Data. This study focuses on a region situated in the southern part of the Bida Basin, a significant inland sedimentary basin in North Central Nigeria. Two distinct methods were employed to estimate crustal thickness from Bouguer anomaly values: (i) an empirical relationship between crustal thickness and Bouguer anomaly, and (ii) spectral analysis of the radial wave number. The average crustal thickness was derived by averaging results obtained from both methods. Additionally, a linear equation (HC = 34.39 – 0.17BG) was formulated for the study area, enabling straightforward determination of crustal thickness from any given Bouguer anomaly value. The estimated crustal thickness in the study area ranges from 32 km to 40 km, aligning closely with the overall crustal thickness of Nigeria as reported by Daniyan et al. (2002). The tectonic stability of the study area, situated on the stable African plate, further underscores its significance within the broader geological context of Nigeria.
