Pedogenesis distribution of mineral sands in the Babylon governorate soils, Iraq

Abstract

The area of ​​Al-Rarangiyah, located in the province of Babylon, was chosen within the sedimentary plain, with an area of ​​9540.36 hectares, which is confined between within longitudes 44⁰12'0" to 44⁰30'0" east and latitudes 32⁰12'0" to 32⁰24'0" north. Prospects are described morphology and sampling The results of the mineral analysis of light sand minerals showed that the percentage of light sand minerals ranged between 90.40 - 97.80%. Quartz is the dominant mineral in light sand minerals, followed by lime and rock pieces.

the decrease in the values ​​of the weathering index is due to the weak weathering of minerals and the high percentage of feldspar, while the increase in the weathering index is due to the decrease The percentage of feldspar and the high percentage of quartz and the possibility of exposure to something of weathering, as it is noted that the weathering index is higher for some horizons soils than it is in the horizons above or below it.
