Rift Zones on Volcanic Islands: Structure, Evolution, and Magmatic
Processes

The objective of this session is to highlight studies about intrusive
growth and the origin and evolution of rift zones on large volcanoes.
The accumulation of intrusions and eruptive centers along active
volcanic rifts may (1) cause deformation at the surface, (2) interact
with gravitational spreading, flank instability, and giant landslides,
(3) result in hydrothermal and structural barriers, (4) promote lateral
migration, accumulation and geochemical diversification of magmas, and
(5) be responsible for the shape of volcanoes. Dynamics of magma
reservoirs at rift zones may also change and interact with other
volcanic, tectonic, and extrinsic processes, while prevolcanic
structures and basement constitution may likewise play an important
role. Studies about the dynamic and structural significance of rift
zones and associated stress and strain, as well as studies about the
influence on petrological and geochemical processes, are welcome. Of
particular interest are comparisons of new findings to existing models
of Hawaii and Iceland. Because of the interdisciplinary nature of this
topic, we encourage contributions on all aspects of intrusion and rift
zone studies, with particular emphasis on dynamic processes, feedback
mechanisms, and petrology.
