I would like to reveal the olivine-spinel phase transformational faulting mechanism responsible for deep-focus earthquakes. I'm studying the following topic.
Deep-focus eartquakes occur at depth from 410 km to 660 km in the slab. By geophysical observations and deformation experiments, the phase transformational... more
Metastable olivine in the slab undergoes the phase transformation to wadsleyite and ringwoodite under differential stress. It is difficult... more
Serpentinazation is important to understand the fulid transportation in the subduction zone because serpentine is hydrous mineral and the dehydration affects the mantle hydration and formation of volcanic arc... more
