Answer:
The most abundant mineral on Earth has just received a name: bridgmanite.
Scientists have known about the mineral for decades but were only able to examine it up close in the past few years. The mineral is normally found deep beneath the surface, but was identified and studied in a meteorite that collided with the Earth 135 years ago.
Formerly known by its chemical name, silicate perovskite (Mg,Fe)SiO3, the mineral was named bridgmanite this month to honor Percy Bridgman, a physicist who won the Nobel Prize in 1946.
The name recognizes Bridgman's "fundamental contributions to high-pressure physics," Chi Ma, a mineralogist at the California Institute of Technology in Pasadena, tells National Geographic.
Ma characterized the material with Oliver Tschauner, an associate research professor at the University of Nevada-Las Vegas, who led the effort.
"This fills a vexing gap in the taxonomy of minerals," Tschauner told the American Geophysical Union.
Likely the most plentiful mineral in the Earth, the mineral had been indirectly studied for decades by measuring changes in earthquake waves as they travel through the planet. The mineral is thought to be found from the bottom of the transition zone of the Earth's mantle down to the planet's core-mantle boundary, at depths between 416 and 1,802 miles (670 and 2,900 kilometers).
Formed Under Intense Heat and Pressure
Bridgmanite is formed from intense heat and pressure, as is found inside the Earth, which causes its atoms to arrange in a unique pattern.
In 2009, Tschauner and Ma started looking for it in the well-known Tenham meteorite, which hit Queensland, Australia, in 1879.
The high-pressure mineral ringwoodite ((Mg,Fe)2SiO4) was first discovered in the Tenham meteorite in the 1960s. Since then, scientists have been investigating high-pressure minerals in the meteorite and others like it, says Ma.
