SOME SULFIDE-SILICATE ASSEMBLAGES FROM THE SAR CHESHMEH PORPHYRY COPPER DEPOSIT, KERMAN, IRAN

چکیده
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. The presence of
bornite grains suggests a partly derivation of copper from biotite. This further
supports the results obtained from the electron microprobe studies of the textural
varieties of biotite. The presence of pyrite in the sericitized parts of biotite grains
suggests a hydrothermal origin for the sericitized biotite enclosed pyrite grains.
