Au-Pd and Bi-Se bearing pyrite and chalcopyrite from the Buchim Copper Mine, Eastern Macedonia

In the Buchim porphyry copper deposit, we determined several representative rare mineral phases, comprising metals from gold-palladium group as well those bismuth-selenium (Cu-Bi-Se-Te-As) group. The phases are represented by new in bismuthinite, galenobismutite, krupkaite, friedrichite, emplectite, laitakarite and native bismuth of gold-palladium, including gold palladium with their elemental mixtures. It should be stressed that both types were pyrite chalcopyrite major ore paragenesis deposit. related to quartz-pyrite-chalcopyrite paragenesis, while a slightly higher temperature, oxido-sulphide parageneses such magnetite-pyrite-chalcopyrite (Mt-Py-Cp) pyrite-chalcopyrite (Py-Cp).
