eastern iran has great potential for porphyry copper deposits, as a result of its past subduction zone tectonic setting that lead to extensive alkaline to calc-alkaline magmatic activity in tertiary time. maherabad is the first porphyry cu-au prospecting area which is discovered in eastern iran. this is related to a succession o f monzonitic to dioritic porphyries stocks that were emplaced with...

introduction two main principal aspects for the genesis of porphyry copper deposits have been determined. the first genetic model concerns the petrologic and geochemical processes and the other relates the genesis to crustal deformation and geodynamic conditions (kesler, 1997). recent studies (e.g., padilla garza et al., 2001) show that the generation and emplacement of porphyry copper deposits...

The Qin-Hang Metallogenic Belt (QHMB), an important metallogenic belt in South China, hosts Cu and W–Sn polymetallic deposits. Tongshanling ore field the QHMB is characterized by coexistence of Cu- W-bearing deposits, which are related to granodiorite granite porphyry. This study examined whole-rock geochemistry, geochronology, Sr–Nd–Hf isotopes determine genetic relationship between diverse or...

Abstract Porphyry copper deposits, the principal source of and molybdenum, form at convergent margins. Copper is precipitated from fluids associated with cooling magmas that have formed in mantle evolved mid- to lower crustal levels, before rising toward surface where they saturate exsolve an aqueous fluid copper. Despite advances understanding their formation, there are still underexplored asp...

Studies of three selected sulfide-silicate assemblages from ore samples from the Sar Cheshmeh porphyry copper deposit led to some ore genetic conclusions. The presence of chalcopyrite blebs in the groundmass orthoclase and quartz from the stock suggests liquid immiscibility in a cooling late-magmatic melt. This is in favor of the orthomagmatic model proposed for porphyry copper deposits. Th...
