Geophysics of the Elang Cu-Au porphyry deposit, Indonesia, and comparison with other Cu-Au porphyry systems [PDF]
ASEG Extended Abstracts, 2012 SUMMARY Elang is a large porphyry Cu-Au deposit situated about 70 km east of Batu Hijau on Sumbawa Island, Indonesia. The deposit is associated with a series of tonalite porphyry intrusions that are hosted by andesitic volcanics. Mineralisation is associated with potassic alteration (chlorite-magnetite±biotite) that produces a discrete magnetic high of

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 ...

Magnetite chemistry in the Dalli porphyry Cu-Au deposit, central Urumieh-Dokhtar Magmatic Arc (UDMA)
Journal of Economic Geology, 2023 The Dalli porphyry Cu-Au deposit is located in the central parts of Urumieh –Dokhtar Magmatic Arc (UDMA). This deposit is formed via the emplacing of Miocene intrusions mainly containing diorite and quartz diorite within the Eocene andesite and ...
