Davemaoite isn鈥檛 found in nature because it can鈥檛 survive outside the high-pressure environment of Earth鈥檚 mantle.
Scientists have discovered a new mineral on the surface of the Earth. There鈥檚 just one catch: it shouldn鈥檛 be here.
Researchers say they've recovered a mineral from deep inside the Earth 鈥 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鈥檚 lower mantle surfaced as diamond inclusion.
Geochemists from 性视界传媒 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鈥檛 hold its structure outside the high pressure of Earth鈥檚 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 性视界传媒 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鈥檚 mantle.
In 1823 the Scottish scientist Sir David Brewster, known at that time for his famed optical experiments, (and inventing the kaleidoscope), described a 鈥渞emarkable new liquid found trapped inside cavities of crystals鈥 and dutifully reported what he had discovered in the Transactions of the Royal Society of Edinburgh science journal.
