Porphyry Indicator Zircons (PIZs): Application to Exploration of Porphyry Copper Deposits
Ore Geology Reviews, 2020 Abstract Magmas with a high oxidation state (FMQ +1 to +2), a high-water content (≥ 4 wt % H2O) and a high degree of fractionation are necessary to form porphyry copper deposits (PCDs). Different proxies, such as Fe3+/Fe2+ ratio of whole-rock, minerals indicative of high oxygen fugacity (fO2) and water content as well as geochemical signatures of ...

Ore Geology Reviews, 2014 Abstract A 418 Ma albite porphyry dike emplaced in a 429 Ma granite pluton in the Hersai porphyry copper deposit (Nom, East Junggar, China) consists of euhedral and pale-orange luminescing albite phenocrysts and groundmass, zircons, blue-violet luminescing apatites and chalcopyrite–sphalerite-rich miarolitic cavities.

Contrasting mineralized and barren porphyries in the Zhongdian Arc, insights from biotite and apatite compositions and halogen fugacity [PDF]
Scientific ReportsCopper mineralization in the Pulang (PL) porphyry deposit, Langdu (LD) porphyry-skarn deposit and Songnuo (SN) porphyry prospect in northwestern Yunnan, China, is closely related to the emplacement of quartz monzonite porphyries.

A zircon case for super-wet arc magmas [PDF]
Nature CommunicationsArc magmas have higher water contents (2-6 wt.% H2O) than magmas generated in other tectonic environments, with a growing body of evidence suggesting that some deep arc magmas may be ‘super-wet’ (>6 wt.% H2O). Here, we use thermodynamic modelling to show
