PGE can be hosted in dif ferent types of rocks f ormed in dif ferent epochs. T he ore- forming condit ion of PGE is also quite special due t o their part icular chem ical charact erist ics such as stable chemical behaviors and refractory of common acid and alkali solutions. P GE m ineralizat ion in porphyry copper deposits belongs to one of the unconvent ional PGE mineralizations and is sig nificant for the underst anding of t he problem how PGE w ere transported f rom lit hosphere t o granite and t hen concent rated in sulfides. T his paper describes t he current status of t he st udy of PGE in porphyry copper deposits in the follow ing f ive aspects: PGE dist ribution, PGE mineralizat ion , platinum g roup minerals, fluid inclusions, and enrichment mechanism. T he main exist ing problems in PGE st udy for por phyry copper deposits, such as unclear influencing f act ors on P GE dist ribut ion , inadequate syst emat ic st udy of fluid inclusions, insuf ficient researches on t he enrichment m echanism of P GE in porphyry c
