Abstract :

Kuh Zar (study area) is located 40 Km west of Torbet Hydarieh and about 5 Km south of . Fadiheb. The study area is part of Tertiary volcanic plutonic belt north of Daruneh fault Vobcanic rocks are mainly intermediate to acid pyroclastic type. They formed during early tertiary time. CaIc-alkaline granodiorite-monzonite-synogranite are intruded some time .mid- tertiary time Mineralization is mainly control by fault system. Several mineralized faults are being discovered. Open space filling features are abundant. In central Kuh Zar, stockwork .mineralization is abundant. The main minerals are: quartz, hematite (specularite),gold barite, siderite, and in some areas some sulfides such as pyrite and chalcopyrite arc noticed. Ancient working is present in the area. Cliloritic and silicification are the mair alteration typcs. Minor argillic is found in some areas. Stream sediment geochemical study show a very broad and high level of gold anomaly. Rock geochemical show very high level of Fe, Au, W, Ag , Cu, Pb, Zn, Ba, andMn. Kuh Zar is an Fe-Oxide Cu-Au typt deposit. The ore bearing fluid was very oxidizing The Au ore grade is between 4 to 10 ppm.
