Tectonic and mantle convection regimes
Conceptual illustration of different styles (regimes) of tectonics and mantle convection, which are relevant for rocky planets.
Subduction zone initiation reconstructions
Subduction zone initiation (SZI) reconstructions for selected events since around 100 Ma. The reconstructed events are based on the whole Earth Sciences community point-of-view of the SZI database.
Puysegur trench formation
A schematic highlighting the formation of the Puysegur trench, New Zealand, where subduction zone initiation may be both horizontally and then vertically driven, according to a 4D evolution model of this margin.
Sea-level change mechanisms (sketch)
Sketches outlining the solid-Earth induced change of sea level over different time periods, covering elastic, viscous, and mantle convection time scales.
Global-scale mantle flow (sketch)
A sketch outlining the link between the viscous convection within the Earth’s mantle and tectonic surface plate motions.
Subduction zone initiation types
Illustration of the three types of subduction zone initiation (SZI) events, namely Newly destructive, Episodic subduction, and Polarity reversal.
Subduction zone initiation forcing
Illustration of the two endmember forcing states, namely vertically and horizontally driven, characterising subduction zone initiation (SZI).
Earth interior model
Simplified model of the Earth’s interior and its global dynamics featuring a solid inner and a fluid outer core, a viscous partially molten but not fluid mantle, and characteristic surface topography.
