   Why is majorite called majorite?

   • Majorite is named after Alan Major, who synthesized this particular type of garnet at pressures of more than 6 GPa at the Australian National University in the late 1960s ( Ringwood and Major, 1971). Compared to normal garnets with a chemical formula of A3 B 2 Si 3 O 12, majorite contains excess Si.

   Where is majorite found?

   • Majorite is believed to be an abundant mineral in the lower transition zone and uppermost lower mantle of the Earth at depths of 550–900 km (340–560 mi). It forms complex solid solutions with other Al, Fe, and Ca-bearing garnets in this region. All of the minerals of the Earth's mantle are made of oxygen as the principal anion.

   What is majorite in physics?

   • P. Fumagalli, S. Klemme, in Treatise on Geophysics (Second Edition), 2015 Majorite is a phase in the mantle that is related to garnet. Majorite is named after Alan Major, who synthesized this particular type of garnet at pressures of more than 6 GPa at the Australian National University in the late 1960s ( Ringwood and Major, 1971).

   What are the properties of majorite?

   • All of the minerals of the Earth's mantle are made of oxygen as the principal anion. It has been reported that a significant property of majorite is that under conditions of high pressure and temperature as exist in the mantle the mineral tends to absorb and store oxygen.

   Does majorite have other phases?

   • No evidence for the presence of other phases is obtained, and the crystals exhibit an equilibrium texture with grain sizes of typically 200–300 nm. c – e, P-wave velocity (c), S-wave velocity (d) and density (e) changes of majorite with pressure and temperature.
