What Makes 30% of the Earth?

A mineral, which makes 30% of the Earth was founded in 1879, but got its name in 2014. Its name is bridgmanite, named after Percy Williams Bridgman, Nobel Prize winner. Geologists have discovered bridgmanite in the lower mantle, and supposed that it takes part in 93% of mantle composition, which makes bridgmanite the most abundant mineral on the Earth.
