The verneshot theory suggests that mantle plumes may cause heating and the buildup of carbon dioxide gas underneath continental lithosphere. If continental rifting occurs above this location, an explosive release of the built up gas may occur, potentially sending out a column of crust and mantle into a globally dispersive, super-stratospheric trajectory
