Porphyry-Cu Deposits of Turkey
, 2019 Turkey, located within the western Tethyan-Eurasian Belt contains numerous porphyry copper deposits formed by the subduction, collision and post-collisional events during the closure of NeoTethys Ocean between the latest Cretaceous and late Miocene. These porphyry systems and associated epithermal and skarn deposits are associated with the subduction ...

Supergiant porphyry copper deposits are failed large eruptions
Communications Earth & Environment, 2022 Monte Carlo-based mass balance simulations suggest that the formation of porphyry copper deposits requires fast accumulation of large magma volumes, which are also capable of destroying those deposits if magmas erupt.

Intrusives associated with porphyry copper deposits [PDF]
Bulletin of the Geological Society of Malaysia, 1977 Porphyry copper deposits and their associated intrusives are widespread throughout the world and particularly abundant in the circum-Pacific region, although not all parts contain porphyry copper deposits.

Geochemistry of Porphyry Deposits
, 2014 Porphyry ore deposits typically form in convergent plate margin or postsubduction settings at depths of 1-6 km. Oxidized hydrous melts derived from the metasomatized mantle wedge transport Cu, Au, Mo, and other metals to upper-crustal magma chambers ...

Assessing the role of tectono-magmatic setting in the precious metal (Au, Ag, PGE) and critical metal (Te, Se, Bi) endowment of Porphyry Cu deposits [PDF]
, 2021 Porphyry Cu deposits commonly contain critical and precious metal by-products, including the chalcophile and siderophile elements, Au, Pd, Pt, Ag, Te, Se, and Bi.

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.

Geosciences, 2014 Porphyry Cu–Au–Pd±Pt deposits are significant Au resources, but their Pd and Pt potential is still unknown. Elevated Pd, Pt (hundreds of ppb) and Au contents are associated with typical stockwork magnetite-bornite-chalcopyrite assemblages, at the central
