Oceanic anoxic events, subduction style and molybdenum mineralization

Solid Earth Sciences, 2016
Nearly half of the world's Mo resources are hosted in Cenozoic porphyries along the east Pacific margin. In contrast, there are essentially no large Mo porphyry deposits along the west Pacific.

Petrogenesis of barren versus mineralized porphyries at the Yechangping deposit, east Qinling: Implications for magmatic controls on Mo–W mineralization

Solid Earth Sciences
The Yechangping Mo–W deposit in the East Qinling Orogen is a giant porphyry-skarn system, but the differences in genesis between its barren monzogranitic porphyry and mineralized granitic porphyry remain poorly defined.

Sulfide saturation in evolving porphyry systems: El Abra porphyry Cu deposit, northern Chile, and the Grasberg-Ertsberg porphyry-skarn Cu-Au district, Papua, Indonesia [PDF]

, 2019
Sulfide saturation during the magmatic evolution of porphyry systems is emerging as an important control on chalcophile element fertility. Platinum group elements (PGE) have extreme sulfide melt-silicate melt partition coefficients that make them ...

Determination of geospatial criteria and prediction of potential areas for porphyry copper deposits in Kazakhstan

Frontiers in Earth Science
Determining spatial parameters related to mineral deposits is crucial for analysing mineral prospectivity. These spatial parameters, called Geospatial Criteria (GC), can serve as input data for modelling mineral prospectivity.

Trace elements and melt inclusion in zircon within the Qunji porphyry Cu deposit: Application to the metallogenic potential of the reduced magma-hydrothermal system

Open Geosciences
The Qunji porphyry copper (Cu) deposit, located within the Awulale metallogenic belt (AMB) in the western Tianshan orogenic belt, exhibits distinct geochemical and mineralogical characteristics that have not been fully understood.

Imperial Porphyry in Roman Britain

, 2018
Imperial porphyry was greatly admired during the Roman and Byzantine periods because the deep purple of the stone was closely associated with the chosen colour of the Emperor. Outcrops of this hard volcanic rock are extremely restricted and only found in

Magmatic-hydrothermal evolution and post-ore modifications of the Halilağa porphyry cu-au deposit, NW Turkey

, 2017
The Biga Peninsula of northwest Turkey is an emerging copper-gold province characterized by numerous epithermal and porphyry-type deposits and prospects associated with Eocene to Oligocene calc-alkaline post-collisional magmatism.
