Geochemical Exploration of drainage Sediments and Heavy Minerals in Sheet 1: 25,000 of the Qazvin

The case study of present project is located in northeast of Qazvin sheet 1:100000 and south of Javaherdeh 1:100000 sheet, in the Hir region. The present study aims to geochemically explorethe Hir region in scale of 1:25000 using stream sediments and heavy minerals exploration method. for this purpose, all data and information of the case study were collected and then, the proper data such as geological map, topography, alteration map, airborne geophysical map and satellite image of digital elevation model, sampling network of the best potential streams as well as heavy mines from potential areas, such as contacts and adjacent intrusions and alterations, was prepared. Then, sampling was carried out and the specimens were transferred to the laboratory for the element analysis. After data analysis, an analysis was performed on them and the errors were resolved by removing the censored data and then, they were normalized by statistical method. Then, the data were statistically analyzed in order to find the areas with mineral potential.
