Abstract

The objective of this paper is to investigate the physical and mineralogical characteristics of the Quaternary formation of the Chad basin. This has been achieved by systematic collection of sediment samples at the depth of 5 and 10 metres respectively in two different locations (sites 1 and 2) in ascertaining the grain size distribution, mineral composition and grain morphology between January and March 2013. Granulometric analyses result showed that particle size distribution ranged from 2 mm to 6 µm across the area suggesting heterogeneous distribution of sandstone and siltstone units. Also, grain morphology results for site1 showed that very angular grains are dominant in both sandstone and siltstone units, while well rounded grains are totally absent. In site 2, sub-rounded grains are dominant in both sandstone and siltstone units. Mineral content analyses result showed that plagioclase and orthoclase feldspars are the most dominant minerals in sites 1 and 2; with about 38.7% and 36% total composition respectively, while zircon is having the least proportion (2.5%) in site 1 and iron oxide with 6% in site 2.
