Oceanic plate age

Colour-blind friendly global oceanic plate age maps with plate boundaries.

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.

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.
