Extended Data Fig. 6: Buoyancies in a subducting slab and upwelling plume.
From: Buoyancy of slabs and plumes enhanced by curved post-garnet phase boundary
The buoyancies of a subducting slab (a) and upwelling plume (b) were calculated using the simple model shown in Extended Data Fig. 5 assuming that each mineral proportion at the phase transitions are 100%. The widths of buoyancies were estimated from the differences in the transition pressures at the ambient temperature and the slab or plume temperature. The buoyancy directed to a shallower depth is expressed to be positive.
