Spatial and temporal distribution of a rhyolite compositional continuum from wet-oxidizing to dry-reducing types governed by lower-middle crustal P-T-ƒO₂-ƒH₂O conditions in the Taupo Volcanic Zone, New Zealand.
A continuum of rhyolite compositions has been observed throughout the Taupo Volcanic Zone (TVZ) over the past 550 kyr. reflecting changes in the ƒH2O, ƒO₂, and P-T conditions in a lower crustal 'hot-zone' (10-30 km) where these evolved melts are generated by crystal fractionation of succes...
