Samakhon prospect area is located in Khorasan Razavi province and NW of Torbat-e-Jam. Lithology of the area includes volcanic, sedimentary and subvolcanic granitoids rocks. One type of mineralization in this area, is vein-veinlet mineralization that hosted by basaltic to andesitic tuff and its 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 formation of mineralization is 178 to 345ºC with 13.7 to 20.6 wt. % salinity. According to the geological and mineralization evidence, a type of mineralization zones of Samakhon area represent the Cu hydrothermal vein-type deposits.
