Volatile-rich intermediate to silicic magmatic systems can feed devastating volcanic eruptions but also generate valuable magmatic-hydrothermal ore deposits that supply most of the world's copper. Understanding geometry, dynamics and timescales these is critical in developing models for predicting occurrence future large eruptions. Here, we use zircon petrochronology from an equigranular monzon...

Abstract At the Exótica deposit, south of giant porphyry copper deposit Chuquicamata (Atacama Desert, Chile), Cu-rich groundwater seeped out at several locations in open pit (Mina Sur) during sampling 2009–2011. their outflows, these solutions formed blueish and greenish copper-bearing gel-like precipitates. These gels contained atacamite sulfate hydroxides such as devilline, spangolite, posnja...

The Sungun porphyry copper deposit that intruded Eocene volcano sedimentary and Cretaceous carbonate rocks hosted by a diorite/granodioritic to quartzmonzonitic stock. Copper mineralization is essentially associated more with potassic and less phyllic alteration. Therefore separating these two kinds of alteration is so important. In this paper, by applying the discriminant, it was attempt to se...
