This study based on compiled world-wide garnet peridotite data confirms the GST in high P and T conditions, which was obtained from Al-free experimental system (MgO-Cr~2~O~3~-SiO~2~) by Klemme (2004).

Serpentinization is potentially significant for the origin and evolution of life during the early history of Earth and possibly on other planets. The dependence of starting materials and their initial ...
