Anomaly Separation of Elements, Based on the Surface Soil Geochemical Data in Kahang Porphyry Copper - NW of Esfahan

The kahang Copper porphyry deposit on Urumieh-Dokhtar magmatic arc, is located in NE of Esfahan. Around of this deposit, Eocene volcanics and pyroclastic rocks ranging in composition from basaltic trachy-andesitic to dacitic are exposed. Granitoids subvolcanic and volcanoplutonic, the causes of alteration and mineralizaton, replacement in Eocene rocks assemblage in afew puls from Oligocene to Miocene. This plutons ranging in composition from monzodiorite quartzdiorite granodiorite to granite with porphyroeidal texture. Alteration and mineralization is classically developed in this deposit. Samples from surface soil were collected in 50m profiles gridding which the distance samplings in along the profile are 25m. The total numbers of samples are 2564 which are analyzed by ICP OES method for 43 elements. In geochemical anomaly maps, activating of faults with another tectonic factors, environmental conditions alteration and erosion in moving and concentration this anomaly are illustrated. Same as the litho geochemical anomalies the most amountdistribution of Cu in the eastern and center of the region, Au in the west and center and Mo in all three region are depicted. In elemental correlation graphs suitable correlation is for Copper and Gold.
