“RINGWOODITE is the most common mineral phase in the lower transition zone of the Earth’s mantle, at depths of 525 to 660 km. This ringwoodite crystal contains about 1% water. If the whole ringwoodite of the mantle contains this amount of water, it is estimated that there is almost three times as much water in the mantle as in all the oceans combined.”
