Abstract

Today, the Environmental studies on the Quaternary regions of sediment are becoming increasingly for various purposes. In this study first Lithological units including the Ophiolite zone of Nosrat-Abad were separated by Remote sensing. Then, using geochemical data of drainage sediments (350 specimen), in order to better identify the contaminated or exposed areas of heavy metals elements of Nickel, Lead, Zinc, Copper and Molybdenum beginning to preparing maps distribution of pollution index (Igeo) and contamination factor (CF). Also, the method of correlation coefficient and cluster analysis, which is a multivariate statistical method, was used in this study for the statistical analysis of the elements. For this purpose, first developed the appropriate change model theory for each of the calculated indices, the Kriging method was used. In order to identify pollution regions on a local scale, especially high and low density, the inverse weighting method of IDW distance is more appropriate. For each of the indices calculated in this study, the inverse distance method (IDW) was used in the GIS environment and the statistical parameters of SPSS software were used. The results showed that the region of Nosrat-Abad has a high contamination in the presence of nickel in the southeast, and the lead element also has a moderate pollution in the south. As a result of separation the Ophiolite units of the region were identified by Remote sensing of the rocks with the nature Basic (Gabbros and Basalts) as the source and inclusive Ni and Cu Elements Available in the region.
