the late eocene-early oligocene sarnowsar granitic rocks and many dacitic to rhyolitic dykesintruded in metamorphosed and metasomatized shale, sandstone, calcite and dolomite marbles andvolcaniclastic and pyroclastic rocks. as a result several million tons of iron ores formed within carbonaterocks in the sangan area. the sarnowsar granitic rocks are mainly granite to granodiorite, metaluminous,...
The Dardvey iron deposit, central part of the Sangan mining area, is located in 300 Km southeast of Mashhad and structural zone of eastern Iran. The Dardvey ore deposit is a typical magnetite-rich skarn developed along the contact of Sarnowsar granite with high magnesium carbonate. Skarn zones of Dardvey deposit comprises of exoskarn, endoskarn and ore zones. The exoskarn zone includes, sub-zon...
Dardvey iron skarn ore deposit is located in the central part of the Sangan mininig area, northeastern Iran. In this study, silicate geothermometr were used to estimate the formation temperatures of skarn zones in Dardvey Fe-skarn deposits. The main metamorphic minerals in prograde and retrograde skarn zones are garnet-clinopyroxene-tremolite/actinolite-amphibole-chlorite-epidote-feldspar-phlog...
