U-Pb zircon and Re-Os molybdenite age of the Siah Kamar porphyry molybdenum deposit, NW Iran

, 2019
The Siah Kamar porphyry Mo deposit is the newly discovered deposit of this type in the Neo Tethys-related Urumieh–Dokhtar magmatic arc, northwest Iran. Mineralization occurs as stock-work quartz–molybdenite and mono-mineralic molybdenite veinlets within ...

Magmatic process recorded in plagioclase at the Baogutu reduced porphyry Cu deposit, western Junggar, NW-China

, 2014
Despite the fact that porphyry Cu deposits contain large amounts of Cu in one or more small stocks, few studies have discussed evidence for significant magma recharge in porphyry Cu deposits.

Asynchronous formation of the adjacent epithermal Au-Cu and porphyry Cu-Mo deposits in the Zijinshan orefield, southeast China

, 2018
Adjacent high-sulfidation epithermal (HSE) and porphyry deposits often have similar Cu-Au metal association, suggesting they are cogenetic and formed contemporaneously.

Magmatic Controls on Metal Endowments of Porphyry Cu-Au Deposits

, 2021
Abstract This overview illustrates the processes controlling magma fertility in the formation of porphyry Cu-Au deposits. Magma fertility means all magmatic parameters (e.g., metal and volatile contents, magma and fluid volumes) that might result in higher amounts of metals, which are exsolvable from the magma.

Major elements geochemistry of chlorite in different ore deposits and its genesis and exploration significance: a case study from Naruo porphyry Cu deposit in Duolong ore district, Tibet

Frontiers in Earth Science
Chlorite is present extensively in many types of deposits. The mechanism underlying the chemical variations in chlorite remains unclear. The Naruo porphyry deposit is a giant copper porphyry deposit in the Duolong ore district of Tibet.

Alteration Lithogeochemistry of an Archean Porphyry-Type Au(-Cu) Setting: The World-Class Côté Gold Deposit, Canada

Characterizing alteration and its geochemical signature provides critical information relevant to ore-deposit genesis and its related footprint; for porphyry-type deposits, zoned potassic-phyllic-propylitic alteration and metal enrichment are critical ...

Redox-controlled generation of the giant porphyry Cu-Au deposit at Pulang, southwest China

, 2019
Some porphyry Cu-Au deposits with relatively reduced ore assemblages, characterized by high hydrothermal pyrrhotite contents and a lack of primary hematite and magnetite, are generally considered to be associated with reduced I-type granitoids.
