Zircon Hf isotope of Iranian porphyry copper deposits: Constraints on the source of porphyry Cu magma

پترولوژی, 2016
In this research, zircon Hf isotopic ratios from Sungun, Sar Cheshmeh, Meiduk, Darreh Zar and Bondar Hoza porphyry mineralized intrusions has been studied. The Hf isotopic ratios in the studied porphyry intrusions are similar and the average of zircon eHf values from Sar Cheshmeh, Meiduk, Darreh Zar, Bondar Hanza and Sungun porphyry intrusions are +8.2,

Divergent Paradigms of Porphyry Cu Deposits in Subduction and Collision Zones

The prevailing view suggests that the formation of porphyry Cu deposits involves differentiation of water-rich, metal-bearing juvenile magmas, with subduction of oceanic slabs supplying the necessary volatiles. However, the occurrence of significant porphyry Cu deposits in continental collision zones, where such volatile sources are absent, challenges ...

Mineralogical and geochemical characteristics of the Skouries porphyry-Cu-Au-Pd-Pt deposit (Greece): Evidence for the precious metal

, 2005
SEM/EDS studies on drill core samples from the deeper parts of the Skouries deposit showed frequent association of magnetite and Cu-minerals (bornite and chalcopyrite) with inclusions of thorite, U-bearing thorite, hydroxyl-apatite and rare earth element

Magmatic-hydrothermal evolution and post-ore modifications of the Halilağa porphyry cu-au deposit, NW Turkey

, 2017
The Biga Peninsula of northwest Turkey is an emerging copper-gold province characterized by numerous epithermal and porphyry-type deposits and prospects associated with Eocene to Oligocene calc-alkaline post-collisional magmatism.
