FAHLORES FROM PORPHYRY Cu-(Mo) DEPOSITS OF THE URALS [PDF]
Минералогия, 2022 The paper describes chemistry of tetrahedrite-tennantite group minerals from three porphyry deposits of the Urals: Mikheevskoe and Tomino porphyry copper deposits on the South Urals and Talitsa Mo porphyry deposit on the Middle Urals.

Gold endowments of porphyry deposits controlled by precipitation efficiency [PDF]
Nature Communications, 2020 Porphyry copper and gold deposits are the dominant natural suppliers of these metals to our society, yet the large variations in metal endowments of porphyry Cu–Au deposits remain obscure.

Redox state of subducted sediments controls porphyry copper mineralization along the Tethyan belt [PDF]
Nature CommunicationsThe Tethyan orogenic belt hosts numerous world-class porphyry copper deposits, with most forming during the Cenozoic continental collision and fewer during earlier Mesozoic subduction.

Porphyry deposits and oxidized magmas
Ore Geology Reviews, 2015 Abstract Porphyry deposits supply most of the world's Cu and Mo resources. Over 90% of the porphyry deposits are found at convergent margins, especially above active subduction zones, with much fewer occurrences at post-collisional or other tectonic settings.

Large Igneous Provinces (LIPs) and Anoxia Events in “The Boring Billion”
Geophysical Monograph Series, Page 449-486., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

How Much Water in Basaltic Melts Parental to Porphyry Copper Deposits?
Frontiers in Earth Science, 2020 Porphyry copper deposits are formed by aqueous fluids exsolved by differentiated, mantle-derived magmas variably mixed with crustal melts. Water is essential to form porphyry Cu mineralization, and this explains why these deposits are found only at ...
