Abstract The Sangan iron ore deposit is located approximately 300 Km southeast of Mashhad, in the Khorasan Razavi province. It is the biggest Iron mine in Eastern Iran. Sangan iron mine comprised of several ore body such as Dardway, Baghak, A, A , B, C, C North. Dardway ore body is located in the southern marginal of the Upper Eocene Sar Nowsar granite (biotite-amphibole granite) and occur in east-west trending sequence of Upper Mesozoic sedimentary rocks. Magnetite skarn, formed in black limestone and dolomite (Jurassic- Lower Cretaceous). They are massive and in some localities they have about 200 meter thickness. Mineral paragenesis are: magnetite ± hematite ± pyrite and some chalcopyrite ± garnet (andradite) ± actinolite ± chlorite ± phlogopite calcite ± dolomite. Dardway is Mg-skarn the Mg content of magnetite is about 1.22-1.26% . At least four stages of skarn formation and ore deposition have been recognized at area (stage I, II, III and IV a, b). Based on the satellite images and field observation, Dardway was displaced by strike slip fault more than one Km from Baghak deposit. Also exploration drill holes and ground magnetic surveys in the study area confirm this motion and dips of mineralization zone are declination towards in South (80°-85°). The recognition of fault system and structural feature are important because it may implication in assessment and exploration of other segment of hidden ore body.
