| Zusammenfassung |
| Magmas that feed volcanoes in the Central Andes must traverse up to 70 km of continental
crust. We observe striking variability in volcano evolution with respect to compositional
range and eruption rates. These result from differences in their plumbing systems,
specifically magma stagnation depth, recharge frequency, volatile content, reservoir
sizes and complexity as well as crustal structure. We combine geochemical and
petrological studies for four end-member systems to better constrain these variables:
