From: Iron diapirs entrain silicates to the core and initiate thermochemical plumes

Interior schematic of iron diapir descent and rise of thermochemical plumes. a depicting the descent of a metal−silicate diapir (stage 1) from an emulsified metal pond, second-stage descent of remaining metal droplets (stage 2) and b ascent of a thermochemical plume (stage 3) and ascent of late stage plumelets (stage 4) from a metal pile at the base of the mantle
