The central objective of this lecture in a deeper understanding of mantle interaction. Topics include: history of ocean basins, formation of MORBs and OIB's, mantle geochemistry, mantle heterogeneity; slab recycling, mantle models (e.g. layered convection model) and mantle reservoirs (e.g. various types of depleted and enriched mantle sources).
