Volcanic activity is one of the main agents responsible for shaping the landscape, environment and climate of planets and moons. On Earth, volcanic eruption can also have catastrophic consequences for human society.
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…
