Abstract :This paper emphasized on the geochemistry of sedimentary iron ore of Shendi- Atbara Basin, River Nile State, Sudan. The main geological units in the study area are composed of Basement Complex insert ignore into journalissuearticles values(Pre-Cambrian);, Nubian Sandstone Formation insert ignore into journalissuearticles values(upper Cretaceous);, Hudi Chert insert ignore into journalissuearticles values(Oligocene); and Quaternary superficial deposit in ascending chronological order. The aim of this study is to investigate the geochemical behavior and geochemical conditions affecting precipitation of sedimentary iron ore. The methodologies have been used to realize the objectives of this study included; fieldwork, geochemical data analyses. Geochemical investigation of studied samples includes chemical analysis such as major oxide analysis insert ignore into journalissuearticles values(Fe2O3, SiO2, Al2O3, CaO, K2O and Na2O); and trace element analysis insert ignore into journalissuearticles values(Cr, Co, Cu, Zn, Mn and Ni); using Atomic Absorption Spectrometry insert ignore into journalissuearticles values(AAS);. The results showed that the origin of iron ore is formed by chemical precipitation during chemical weathering of the rocks from surrounding areas. The study of iron ore showed that, the environmental conditions under which iron ore are formed were lacustrine environment and warm temperature. Concentration of Fe2O3 in the study area ranges between maximum 79.52% in Goz Alhaj area to minimum 27.22% in Alkarbican area and the average is 53.37% indicate that the quality of iron ore is good according to international standards. All these results have been to construct isoconcentration maps of the iron ore distribution in study area and potentiality for future mining works.
