Abstract: 

Pariz area is located in south-west of Kerman province, within the Urmia-Dokhtar volcano-plotonic belt and copper mineralization belt of Iran. The aim of this study is to identify the Cu high-potential areas in Pariz using stream-sediment geochemical studies. In this regard, 392 stream-sediment samples were used and they were analyzed by ICP-MES instrumental analysis for 15 elements. After applying the necessary pre-processing including replacement of censored data, remove the syngenetic component, outlier data correction and normalization; multivariate statistical processes were applied on data. Considering the vector origin of the stream-sediment samples, the network estimation method was used to produce geochemical maps. The geochemical maps were validated by the Cu occurrences in the region. According to the ratio of “percentage of overlay of the occurrences to the percentage of desirable area”, it can be stated that the enrichment index method has the best performance for identification of high-potential areas.
