Genesis of Dacitic Magmatism at Batur Volcano, Bali, Indonesia : Implications for The Origins of Stratovolcano Calderas

---

Batur is an active statrovolcano on teh island of Bali, Indonesia, with a large, well-formed caldera whose formation is correlated with the erupstion about 23.700 years ago of a thick ignimbrite sheet. Our study of the volcanic statigraphy and geochemistry of Batur shows teh formation of the caldera was signalled by a change in teh composition of the erupting material from basaltic and andesitic to dacitic. Teh dacitic rocks are glassy, prossess equilibrium phenocryst assemblages, and display compositional characteristics consistent with an origin by crystal-liquid fractionation.
