The Kalmakyr deposit in Uzbekistan is one of the world’s largest gold-rich porphyry Cu deposits, and mineralization was proposed to be closely associated with emplacement latest intrusive phases, that is, granodiorite porphyry. However, it still unclear which features these ore-bearing intrusions are crucial for enormous metal enrichment how they correlate magmatic fertility. In this study, we ...

With a focus on the Cu isotope geochemistry of chalcopyrite, this paper analyzed Qibaoshan crypto-explosive breccia-type Cu–Au polymetallic ore district in Wulian, Shandong Province, North China Craton (NCC). Combined with results situ sulfur analysis sulfides, certain reference and evidence for study genetic mechanism epithermal-porphyry metallogenic system were provided. The show that δ34S va...

Porphyry Cu-Mo deposits are among the world’s largest source of Cu, Mo, and Re, also an important other trace elements, such as Au Ag. Despite fact that chalcopyrite, bornite, pyrite most common sulfides in this deposit type, their element content remains poorly constrained. In particular, little is known about minor elements partitioning into Cu-(Fe) a function temperature pH hydrothermal flui...

the study area is a part of cenozoic magmatic belt of central iran, which is located in the west of yazd porovince. contact metamorphism and skarn occurred in conglomerate part of sngestan formation. the oligocene intrusion bodies of ali-abad-darreh zereshk are leucocerate and have the chemical composition of granite to granodiorite with calc-alkaline affinity from volcanic arc geological setti...
