Granulometric Analysis Of Bima Sandstone Around Chekole In Gombe Sub-Basin Of The Upper Benue Trough, Nigeria
Keywords: Granulometric analysis, Bima sandstone, Upper Benue Trough, Nigeria
Abstract—The study investigates the grain size distribution of Bima sandstone formation exposed around Chekole in North-eastern Nigeria and determines the condition of their deposition. This has been achieved by collecting sediment samples from the exposed outcrops of Bima sandstone formation in various locations across the study area. The granulometric analyses suggest that the texture of the Albian sedimentary formation ranged from gravely to coarse grained sand. Other components include medium and fine grained sands. Statistical parameters indicate that the sorting of these sediments ranged between moderate and poorly-sorted, the skewness values show that over 90% the samples analysed are positively skewed. Kurtosis values ranged from platykurtic to leptokurtic.
