This study investigated the forms and distribution of Iron (Fe) oxide in soils developed from four different parent materials in Nigeria, and their relationship with some soil physical and chemical properties. Composite soil samples were collected at soil depths of 0–30cm, 30–60cm, 60–90cm and 90–120cm from Idanre (Basement complex) in Ondo State. Koko (Alluvium) in Delta State, Nigeria Institute for Oil Palm Research (NIFOR) (Coastal Plain Sands) and Uhonmora (Shale) both in Edo State, Nigeria. The soils were analyzed for the physical and chemical properties, using standard laboratory techniques. The concentrations and forms of Fe were extracted using the total Ammonium Oxalate Extract (Amorphous forms), Citrate – Bicarbonate Dithionite Extract (Crystalline forms) and the Pyrophosphate solution (Amorphous organic forms). Data obtained were subjected to statistical analysis and the mean separation was carried out using the Duncan Multiple Range Test (DMRT). Results showed that the concentrations of iron oxides in the soils were higher than those of aluminum and manganese in all the locations. The crystalline free oxides dominated the soils in Shale, Hydromorphic, Coastal plain sand and Basement Complex. They had mean concentrations ranging from 1.46–5.71mgkg-1 (mean of 3.40mgkg-1). The Amorphous forms of Fe oxides were generally lower than other oxides in the four locations. The lowest mean concentration for all the oxide forms were found in Coastal plain sand compared to shale which had the highest concentration. Correlation studies showed that there was a positive and significant (p>0.5) correlation between clay and other parameters, suggesting that the oxide concentration increased with the prevalence of clay in all the location studied.
