Constraining fluid and sediment contributions to subduction-related magmatism in Indonesia: Ijen Volcanic Complex

Abstract:

Ijen Volcanic Complex (IVC) in East Java, Indonesia is situated on thickened oceanic crust within the Quaternary volcanic front of the Sunda arc. The 20km wide calderas complex contains around 22 post-caldera eruptive centres, positioned either around the caldera-rim (CR) or along a roughly NE-SW lineament inside the caldera (IC). The CR and IC lavas exhibit separate differentiation histories. Major element and trace element modelling shows that fractionation of olivine, clinopyroxene, Fe-Ti ...
