Statistical Analysis of Sedimentology and Sedimentary Geochemistry Data of Aeolian Sediments in Khuzestan Province

The Khuzestan plain is located in south western of Iran and is covered about 3.9 percent of the country area. Khuzestan plain is mostly covered by the Quaternary deposits. The thickness of these deposits exceeds 300m in some areas .Sedimentology and geochemistry of sand dunes producing centers are not only important for determining sedimentary and geochemical features of the particles possible origin, but also is important for determining the environmental geochemistry characteristics of these particles and their role in environment and air pollution. In this study, based on standard sampling methods of surface sediments, 35 samples, for sedimentary and sedimentary geochemistry analyses were taken from sand dunes in five areas of the Khuzestan plain. The samples were investigated by sedimentary grain size and chemical analyses in  Geological Survey of Iran laboratories. The results indicate that the deposits size distribution is classified as sand, muddy sand and minor amount of gravel. Statistical parameters of sedimentology and morphoscopic studies often indicate wind source influenced by fluvial processes sources. Sedimentary geochemistry data, and statistical analysis i.e. factor and cluster analysis (using SPSS software), indicate  two main sources of elements in the Khuzestan plain aeolian sediments includes geogenic (Cu, Li, Nb, Ni, Th, V, Zn, La, Pr); and anthropogenic sources (Zr, Ba, U, Sr) . The main anthropogenic sources are chemical pollution and petroleum industrial activity.
