This thesis presents the results of a geochemical study of the Banda Arc (East Indonesia) where magma genesis is influenced by subducted source components that are controlled by an active arc-continent collision. The main objective of this study is to investigate the role of subducted continental material on the magma genesis using isotopic and chemical compositions of samples from volcanoes an…
Kelimutu is a stratovolcano that has three crater lakes containing exotic fluids. This study presents the analytical results describing the chemistry of each lake, interprets the chemistries in terms of water-rock interactions and volcanic fluxes, and derives a physical lake model that delineates the parameter-window for volcanic crater lake existence.
