Abstract
This study is an investigation on geochemical exploration and economic geology of Qare-Naz 1:50,000 sheet, western Zanjan province. The scope of the study is to presentation of mineral pomissing area in a regional scale. For this reason, geochemical sampling was initially performed. The samples were analyzed by emission spectrometry, polarography and ICP methods. Then the results were processed using statistical methods. Anomaly samples were separated by method. In the control phase, the geochemical anomalies were studied using heavy mineral and economic geology studies viewpoint (field observation, study of polish and thin sections prepared from the mineralized zone as well as the analytical results for samples obtained from these zones). Combination of these results with geochemical anomalies the mineral promissing areas were defined, As follows: A) North – Northeast area has elements anomalies Au, Pb, Zn, Cu. B) Northwest area has elements anomalies Cu, Au, Fe, Mo, Bi and W. C) South – Southwest area has elements anomalies Cu, Pb, Zn, Mo, Mn and S.
