Magmatic Evolution at the Saindak Cu-Au Deposit: Implications for the Formation of Giant Porphyry Deposits

open access: yes
The Chagai porphyry copper belt is a major component of the Tethyan metallogenic domain, which spans approximately 300 km and hosts several giant porphyry copper deposits. The tectonic setting, whether subduction-related or post-collisional, and the deep

Deep Exploration Porphyry Molybdenum Deposit in Dasuji, Inner Mongolia: Insight from Aeromagnetism and Controlled-Source Audio-Magnetotellurics

open access: yes
Porphyry molybdenum deposits hold significant potential for deep exploration. However, in the Dasuji molybdenum deposit, quartz porphyry, granite porphyry, and syenogranite are sporadically exposed beneath low mountains and hilly terrain, limiting the ...

Specificity of Ore Generation (Tin, Pegmatites, and Gems) in Trans-Porphyry Deposits

open access: yes
During the magmatic stage, base and rarer metals segregate from silicate melts to form ore deposits. The usual case is the porphyry (PD) type (Cu, Mo, and W) above subduction zones. The metal grade increases from some ppb or ppm up to percent levels.

Analysis of trace element distributions distal to porphyry copper deposits

open access: yes, 1996
Enrichment and depletion of trace elements occurs in host rocks distal to porphyry copper deposits as a result of hydrothermal metasomatism. Subtle geochemical distributions in weakly propylitized host rocks is sufficient to indicate proximity to a ...
