Abstract

The studied area is located in the east of Haji - Abad village, Markazi Province, central Iran. The oldest geological units of this area are volcanic and volcanic-sedimentary rocks with Eocene age. Geochemical and heavy mineral systematically Explorations were applied in the area and during it, 141 silt samples and 59 heavy mineral samples were collected. Data from chemical analysis of samples were subjected to data processing with (Spss) such as correlation factor analysis and cluster analysis. To calculate background and anomaly value, the non-structural method and structural method (fractal method - area) were used and maps were drawn by IDW (Inverse Distance Weighted) method with ArcGis software and compared with each other. In the following, five ranges were selected for field control and it shows the effects of copper mineralization in andesite rocks on andesite basalt porphyry located in the north of the range. The maximum amount of copper in the rock samples taken from this unit was 3.57%. Copper minerals in three phases. Sulfide copper minerals are chalcopyrite, bornite, chalcocite, digenite, covellite, and oxide copper minerals are tenorite and cuprite, and also carbonate copper minerals are azurite and malachite. Cooper mineralization's textures are replacement, filling open space and veins. Eventually can be said that the copper mineralizations observed in this area have a significant similarity with Manto-type deposits
