Session ID#: 51960

Session Description:
Oceanic intraplate volcanism can be related to mantle plume activity and/or within-plate tectonic processes. The interplay between tectonic, volcano-tectonic, and igneous activity control compositional evolution, growth, and destruction of seamounts and ocean islands. These processes have been a focus of research for many years, but are only partially understood. Processes and timescales controlling the evolution of oceanic intraplate volcanoes, and their geometry and longevity, can be studied at macroscopic- to microscopic scale. The integration of these processes in a coherent holistic view, however, is key to our comprehension of ocean island volcanoes and their origins.

The aim of the session is to discuss recent research on a variety of topics on (submarine and subaerial) oceanic intraplate volcanism, to test similarities and differences between the various volcanic groups/archipelagos, and to improve our understanding of evolution and processes of oceanic intraplate volcanoes in general.
