Abstract:
Ten sediment samples were collected from the lbai River estuary. The sediments were
analyzed to determine the clay mineral contents and to study the sediment texture in the
lbai River estuary surface sediment. The mineralogy was analyzed using the X-ray
diffractometer (XRD) while the texture analysis was determined using the wet sieving
method. Generally, the sediments in Ibai River are low in clay mineral contents, where
quartz is dominant in the area, which was over 70%. Thus, the study also indicates that
the study area, is dominated by primary minerals. In addition, trace amount of other
minerals such as feldspar kaolinite micas and chlorite also revealed in this study. Texture
analysis shows that the dominant texture in the sediment is clay especially at stations 6, 7,
8, 9 and IO. However, sand texture was dominant the sediment at the river mouth of the
estuary.
