Abstract

In order to study the effect of sedimentary environments on the iron and manganese crystallization indices. Six districts were selected in al-Anbar governorate, including al-Baghdadi, Heet, Abu Tayban, Ramadi, Khalidiya and Falluja district. Two pedons were taken for each region and two different environments, one was for the sedimentary and the other was for desert laid in a vertical direction on Euphrates River. The total iron, manganese, available iron , manganese, Crystalline Free Iron, manganese Oxides, and Amorphous iron, manganese oxides have been measured as well as calculation of crystallization indices for iron and manganese. The Results showed that the over the crystallization of iron and manganese index in desert soils was superior sedimentary soil, as well as the iron crystallization index compared with the manganese crystallization index with a presence in pattern distribution in the desert soil compared to the sedimentary soil affected by the movement and the transfer of clay from the surface horizons to sub horizons. The percentage of organic matter was effected negatively on the percentage of crystallization index in the surface horizon and for all environments .
