Pulsed magmatic fluid release for the formation of porphyry deposits; tracing fluid evolution in absolute time from the Tibetan Qulong Cu-Mo deposit

The magmatic-hydrothermal evolution of porphyry-style mineralization in the shallow crust that is linked to magmatic processes at depth has been extensively studied using bulk-sample isotopic analysis combined with relative timing constraints. However, a lack of evaluation of the fluid evolution pro...
