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 pr...

• A petrogenetic framework for textures in the archetypal Yerington porphyry system. textural toolkit deposit exploration. Formation of pegmatitic pods, USTs and massive silica bodies due to undercooling. Thermometry aplite dykes indicates intrusion hotter melts from depth. Miarolitic cavities record timing fluid exsolution mineralisation. Porphyry-type deposits are spatially temporally associa...

The magmatic-hydrothermal evolution of porphyry-style mineralization in the shallow crust that is linked to magmatic processes at depth has been extensively studied using bulksample isotopic analysis combined with relative timing constraints. However, a lack of evaluation of the fluid evolution process against an absolute time frame limits further understanding of the ore-forming process. Here,...

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...

Numerical analysis of geophysical data to uncover Precambrian belts and probably enclose mineral deposits is becoming once more communal in mining activity. The method founded on typifying zones branded comprehend looking for analogous areas. proposed work outlines a semi-automatic image processing system the structural investigation Bou Azzer inlier, which varies from preceding approaches as i...
