Abstract :
Kahang Cu Porphyry deposit is situated in the central part of a major Iranian magmatic belt, Urumieh-Dokhtar, in central Iran.
There are several sub-volcanic stocks (e.g., porphyric granitoids rocks, quartz monzonite, diorite and monzodiorite-monzogranite)
within Eocene volcanic and pyroclastic rocks consisting of basaltic, trachy-andesite and dacitic rocks. Hydrothermal alterations at the
Kahang deposit have an extended range and exhibit a concentric zoning pattern including potassic, phyllic, argillic and propylitic
from the center to the margin. The aim of this study was to identify geochemical particulars by geochemical applications in 184 rock
samples in these potassic, phyllic and argillic alteration zones. The results of this study show that there are high values of K, Mg and
Cu in the potassic zone (located in the central part), main Mo anomalous parts and high Cu values can be found in the phyllic zone
(eastern part), and high values of Au, Ti and Al are concentrated in the argillic zone (western part) . Overall, the Kahang deposit
hosts Cu, Mo and Au mineralization in these three zones.
