Oceanic hotspot origin and dynamics (co-organized)
Convener: G. Helffrich  | Co-Convener: G. Laske 
Add this session to your Personal programme

The development history of hotspots in oceanic environments differ depending on their geodynamic environments. Pacific hotspots, exemplified by Hawaii, develop from seamounts, emerge to volcanic islands, and then subside to a guyot stage. Atlantic hotspots develop to an emergent volcanic island yet resist subsidence and continue uplifting. This session aims to document these differences geologically and geophysically with the aim of understanding how different evolutionary histories arise geodynamically.

Invited speakers include: R. Ramalho (U. Muenster), N. Ribe (UPMC Orsay).
