Supergiant porphyry copper deposits are failed large eruptions

open access: yesCommunications 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.

Porphyry Cu(Mo) deposits of the Urals: insights from molybdenite trace element geochemistry [PDF]

open access: yes, 2019
The first data on EMPA and LA-ICPMS study of molybdenite from four porphyry deposits of the South and Middle Urals (Tomino, Mikheevskoe and Benkala porphyry Cu and Talitsa porphyry Mo deposits) are presented.

Contrasting apatite geochemistry between ore-bearing and ore-barren intrusions of the giant Kalmakyr gold-rich porphyry Cu deposit, Tien Shan, Uzbekistan

open access: yesFrontiers in Earth Science, 2023
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 the emplacement of the latest intrusive phases, that is, granodiorite porphyry.

Geology and mineralization of the Tiegelongnan supergiant porphyry-epithermal Cu (Au, Ag) deposit (10 Mt) in western Tibet, China: A review

open access: yesChina Geology, 2022
The Tiegelongnan Cu (Au, Ag) deposit in central Tibet contains more than 10 Mt of copper ranking 29th in the world. It is characterized by typical porphyry-epithermal alteration and mineralization.

Oceanic anoxic events, subduction style and molybdenum mineralization

open access: yesSolid 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.

Critical Factors Controlling Pd and Pt Potential in Porphyry Cu–Au Deposits: Evidence from the Balkan Peninsula

open access: yesGeosciences, 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
