Abstract :
The purpose of this study is to identify the favorable areas for mineralization based on hierarchical cluster analysis of stream sediment geochemical data in the western part of the 1:100,000 Tafresh geological sheet in the Urmia-Dokhtar structural zone of Iran. The geochemical data used in this research come from 520 stream sediment samples gathered and analyzed by the Geological Survey of Iran. The samples were chemically analyzed for 19 elements. The elemental correlation coefficients and para genesis were found by applying Pearson correlation and Ward cluster analysis. In the first cluster: Copper, Zinc, Mercury, Antimony, Cadmium, Cobalt, Bismuth, Strontium, Yttrium and Tungsten and in the second cluster: Arsenic, Silver, Tin, Lead, Nickel, Chrome, Vanadium, Barium and Scandium were placed. Anomaly contour maps showed that the elements in a category have confirmed each other anomalies and the elements with high correlation coefficient have good overlap anomaly maps. Field observations have verified Copper and Zinc mineralization in the study area.
