Igneous breccia system of the Shand porphyry Cu-Mo deposit, Northern Mongolia

open access: yesMongolian Geoscientist, 2022
The Shand Cu-Mo deposit is located in the Orkhon-Selenge depression, Northern Mongolia. It lies near the Erdenetiin Ovoo porphyry Cu-Mo deposit, which together define one of Northern Mongolian’s most economically significant metallogenic belts.

Determination of oxygen fugacity from ore-bearing magma responsible for Gazu copper mineralization: Cerium data in zircon mineral [PDF]

open access: yesپترولوژی, 2021
Porphyry Cu deposits are typically oxidized. Oxygen fugacity (fO2) is a key factor, which controls the formation of porphyry Cu deposits. Trace element compositions of Cretaceous magmatic zircon grains (65.9-65.1 Ma) were determined from ore-bearing ...

Fahlores from Porphyry Cu–(Mo) Deposits of the Urals

open access: yesGeology of Ore Deposits, 2022
The paper describes chemistry of tetrahedrite 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. In the deposits studied tetrahedrite group minerals deposited either with late mineral assemblages of the porphyry stage or within

Oxidized sulfur-rich arc magmas formed porphyry Cu deposits by 1.88 Ga

open access: yesNature 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 ...

Diagenetic and metallogenic ages, and geological significance of the Fujiashan skarn-type(Cu-) W Deposit, southeastern Hubei Province

open access: yes地质科技通报, 2021
The Fujiashan(Cu-) W Deposit, which is discovered recently, is one of the typical skarn deposit in southeastern Hubei.The(Cu-) W mineralization is closely associated with the Fujiashan granodiorite porphyry.In order to accurately determine the diagenetic

Melt Inclusions in Veins: Linking Magmas and Porphyry Cu Deposits [PDF]

open access: yesScience, 2003
At a porphyry copper-gold deposit in Bajo de la Alumbrera, Argentina, silicate-melt inclusions coexist with hypersaline liquid- and vapor-rich inclusions in the earliest magmatic-hydrothermal quartz veins. Copper concentrations of the hypersaline liquid and vapor inclusions reached maxima of 10.0 weight % (wt %) and 4.5 wt %, respectively.

Supergiant porphyry Cu deposits are failed large eruptions [PDF]

open access: yes, 2021
Abstract Porphyry copper deposits, the principal natural source of Cu and Mo, form at convergent margins. Copper is precipitated from fluids associated with cooling magmas that have formed in the mantle and evolved at variably deep crustal levels, before raising close to the surface where they exsolve fluids and copper.

SULFUR SOURCES OF SULFIDES OF THE AK-SUG CU-AU PORPHYRY DEPOSIT, EASTERN TUVA [PDF]

open access: yesМинералогия, 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
