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.

Schematic tectonic reconstruction of the Sunda-Java SZI event (modified from Hall, 2012). Subduction of the Indo-Australian plate at the Sundaland margin has been episodically ongoing since >100 Ma. The most recent episode occurred at ca. 40–60 Ma and it initiated the new Sunda-Java subduction zone. Shown are the new subduction zone (pink line), other active (solid purple lines) and inactive (dashed purple lines) subduction zones, spreading ridges (solid red lines), and transform faults (red dashed lines).

Sunda-Java subduction zone initiation

The Sunda-Java SZI event might have re-started subduction at the southern margin of Sundaland at around 60–40 Ma.
