Oxidized sulfur-rich arc magmas formed porphyry Cu deposits by 1.88 Ga
Nature Communications, 2021 Tectonomagmatic conditions in the Precambrian were hypothesized to be unfavorable for porphyry Cu deposit formation. Here, the authors show that metallogenic processes typify Phanerozoic porphyry Cu deposits operated by ~1.88 Ga, reflecting modification ...

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.

Porphyry indicator zircons (PIZs): Application to exploration of porphyry copper deposits
Ore Geology Reviews, 2020 Abstract Magmas with a high oxidation state (FMQ +1 to +2), a high-water content (≥ 4 wt % H2O) and a high degree of fractionation are necessary to form porphyry copper deposits (PCDs). Different proxies, such as Fe3+/Fe2+ ratio of whole-rock, minerals indicative of high oxygen fugacity (fO2) and water content as well as geochemical signatures of ...

Petrography, geochemistry, and tectonic setting of intrusive bodies of the Seridune deposit, northeast of Sarcheshmeh mine, Kerman Province, with an emphasis on Seridune porphyry intrusive body [PDF]
پترولوژیIntroductionThe Cenozoic Urumieh–Dokhtar magmatic arc (UDMA) in Iran is a part of the Alpine-Himalayan orogenic belt hosts well-known porphyry Cu ± Mo ± Au ± Ag and epithermal Cu (± Au) deposits (McInnes et al., 2003; Hou et al., 2011; Richards et al ...

SULFUR SOURCES OF SULFIDES OF THE AK-SUG CU-AU PORPHYRY DEPOSIT, EASTERN TUVA [PDF]
Минералогия, 2019 The paper presents the S isotopic composition of sulfides from the Ak-Sug Au-Cu-porphyry deposit hosted by Early Proterozoic magmatic rocks. The S isotopic composition of sulfides varies from +1.0 to +3.2 ‰: +2.5 to +3.2 ‰ for molybdenite-I, +1.0 to +3.1

American Mineralogist, 2022 AbstractPorphyry Mo deposits have traditionally been classified into two major classes, arc-related and Climax-type, based on the tectonic setting and chemistry of associated intrusions. Although there is a consensus that porphyry Mo systems were formed by the optimal coincidence of geological processes operating at different scales, it is unclear what

Geological Journal, EarlyView.The composition of intrusive rocks suggests that the magma was likely generated in a subduction‐related setting. The arc crustal thickness in the Phnom Sro Ngam and Halo Prospects was probably < 40 km during emplacement. Zircon U–Pb age range indicates a correlation with Loei Fold Belt magmatic activity.
