Davemaoite isn’t found in nature because it can’t survive outside the high-pressure environment of Earth’s mantle.
Scientists have discovered a new mineral on the surface of the Earth. There’s just one catch: it shouldn’t be here.
Researchers say they've recovered a mineral from deep inside the Earth — one they thought would never see the light of day.
Scientists never thought such a mineral could be found at the planet's surface.
New mineral from Earth’s lower mantle surfaced as diamond inclusion.
Geochemists from UNLV have discovered a new mineral on Earth's surface that's believed to have originated 410 miles deep within the planet's lower mantle.
What looked like imperfections turned out to be a natural sample of davemaoite, a mineral that can’t hold its structure outside the high pressure of Earth’s lower mantle.
Davemaoite hitched a ride inside a diamond, traveling all the way up from the planet's lower mantle.
Scientists previously synthesized the mineral in a lab using immense amounts of pressure, but they were surprised to find it in nature.
Mineralogists from the University of Nevada, Las Vegas are reporting the surprising discovery of a new mineral. Called calcium silicate perovskite, traces of the mineral were discovered in a diamond formed deep in the earth’s mantle.
In 1823 the Scottish scientist Sir David Brewster, known at that time for his famed optical experiments, (and inventing the kaleidoscope), described a “remarkable new liquid found trapped inside cavities of crystals” and dutifully reported what he had discovered in the Transactions of the Royal Society of Edinburgh science journal.
