5 de nov. de 2016 · Porphyry deposits form at depths of 2–4 km (Sillitoe 2010). Thicker overriding continental crust means longer distance for the porphyry to penetrate. Moreover, the difference between 30–35 km and 45–55 km in thickness has no effect on SO 2 degassing, because high pressure experiments show that SO 2 is not stable under the pressures, temperatures and oxygen fugacity of porphyry deposit ...

26 de ene. de 2021 · We tested this hypothesis through an integration of all the relevant data available from the main Andean porphyry copper deposits. This region was selected because it constitutes by far the largest known Cu concentration in the planet (985 Mt of Cu; Sillitoe, 2012) and individual deposits of the belts include the largest known concentrations of Cu and Mo in the Earth’s crust (Sillitoe, 2010).
Preamble. The Talapoosa district is underlain by the Kate Peak Formation, a sequence of volcanic and epiclastic rocks of mid-Miocene age. The sequence is dominated by andesitic to dacitic flows, breccias and tuffs, but also includes volcanic domes and shallowly emplaced minor intrusions. The Bear Creek and nearby gold-silver zones, 2-3 km ...
