Abstract

Samakhon prospect area is located NW of Torbat-e-Jam in Khorasan Razavi Province. Lithology of the area includes volcanic, sedimentary and subvolcanic granitoids rocks. One type of mineralization identified in this area is vein-veinlet that hosted by basaltic to andesitic tuff in contact with limestone. Primary minerals are chalcopyrite, pyrite, and bornite and secondary minerals includes malachite, chalcocite, covellite, hematite, goethite and azurite. The most important gangue mineral with mineralization is quartz that is observed as filling open space and veinlet. Mineralization has anomaly of Cu (4.5 %) and other elements have no economic value. Based on fluid inclusion studies in quartz mineral, temperature during the formation of mineralization is 178 to 345ºC with 13.7 to 20.6 wt. % salinity. According to the geological and mineralization evidence, mineralization zones in the Samakhon area represent the Cu hydrothermal vein-type deposits.
