Basaltic and kimberlitic volcanism: comparisons, contrasts and controversies
(session V18)

There have been considerable advances in our understanding of kimberlitic volcanism in recent years, driven mostly by detailed studies of recently discovered Canadian occurrences, but also by re-appraisals and new work on some of the "classic" southern African occurrences. The motivation for this session is a desire to generate a constructive debate on the similarities and differences of kimberlite and basaltic volcanoes. The session will be an ideal forum for presenting any field-based, experimental and theoretical studies that compare and contrast any aspects of the eruption mechanisms, the sub-surface and surface emplacement processes and their products at kimberlitic and basaltic centers. We particularly welcome studies that evaluate the uniqueness of kimberlitic volcanism. However, we also seek out presentations that emphasize the differences, including those that place kimberlite volcanoes in a special category.
