Abstract Porphyry-type deposits are the world’s main source of copper and molybdenum provide a large proportion gold other metals. However, mechanism by which mineralising fluids extracted from magmas transported upwards into ore-forming environment is not clearly understood. Here we use field, micro-textural geochemical techniques to investigate field relationships samples circa 8 km deep cros...

Porphyry systems supply most copper and significant gold to our economy. Recent studies indicate that they are frequently associated with high Sr/Y magmatic rocks, but the meaning of this association remains elusive. Understanding the association between high Sr/Y magmatic rocks and porphyry-type deposits is essential to develop genetic models that can be used for exploration purposes. Here we ...

molybdenite occurs in five forms in the sar cheshmeh porphyry copper deposit, namely, (1)-veinlets with quartz-molybdenite, (2)-veinlets with quartz-molydenite that were filled with pyrite, (3)-veinlets with quartz-molybdenite-pyrite–chalcopyrite, (4)-molybdenite veinlets with very low quartz and (5)-disseminated molybdenite grains. because of their large size, the veinlet-related molybdenite g...

The Sungun  copper  porphyry deposit is hosted by a Tertiary magmatic complex in  the  Azarbayjan province , northwestern Iran. The  Sungan mine  in its southern and eastern parts is limited  by early Miocene volcanic and by Late Cretaceous limestone rocks in northern and eastern parts respectively . The Sungun  deposit is associated with a suite of porphyritic granitoids and late dikes intrudi...

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...
