The 15 June 1991 Eruption of Mount Pinatubo. I. Phase Equilibria and Pre-eruption P-T-fO2-fH2O Conditions of the Dacite Magma
Crystallization experiments were carried out on a representative sample of the crystal-rich dacite ejected during the 15 June 1991 eruption of Mt Pinatubo, to define the pre-eruption conditions of this major volcanic event. Experiments were performed in the temperature and pressure range of 750-900[...

| Zusammenfassung: | Crystallization experiments were carried out on a representative sample of the crystal-rich dacite ejected during the 15 June 1991 eruption of Mt Pinatubo, to define the pre-eruption conditions of this major volcanic event. Experiments were performed in the temperature and pressure range of 750-900[degrees]C and 220-390 MPa, respectively. Redox conditions were varied between those of the NNO (nickel-nickel oxide) buffer and 2[middot]7 log fO |
