Faulting triggered by the phase transition of olivine

Caption

Left: Formation of lenticular packets filled with nano-crystalline olivine/wadsleyite. Right: Shear localization on the weak layer which is formed by the coalescence of the lenticular packets. This results in shear heating followed by faulting and deep-focus earthquakes.
