Video: An analogue model of “slab break-off”: a process where part of the lithosphere, in this case oceanic, detaches after it has undergone subduction.

Due to the relatively high density of oceanic lithosphere, it can sink into the hot upper mantle, a process we call subduction. Subduction progresses until all oceanic material has been consumed in the upper mantle, thereby forcing adjacent lighter continental lithosphere to subduct as well. When the subduction stalls, the dense oceanic material slowly separates from the lighter continental material by breaking.
The detached plate sinks slowly into the asthenosphere, towards the upper-lower mantle boundary (here the bottom of the tank). The time scale of such a process is minutes to hours in the laboratory, but millions of years in nature.

The material that simulates the lithosphere is a mix of organic plasticine, PDMS putty, silicon oil and iron powder (called “60OPL 40PDMS 24oil” in Broerse et al., 2019), which has a stress-dependent strength (non-Newtonian). The material that is used to simulate deformation behaviour of the asthenosphere is glucose with a Newtonian rheology. The tank in this experiment has dimensions (w x l x h) 34.5cm x 44.5cm x 20cm.
