MECHANICS and TECTONICS: Mantle plumes: crustal structures, topographic expression and tectonics
To Plume or not to Plume?
A debate on fundamental questions about the dynamics of the processes that lead to plumes, LIP’s, hot spots and intra-plate volcanoes. The discussion will concentrate on processes that effect continental lithosphere, as they are relevant to the Australian continent and mineral deposits that still have questionable origin.
