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 ҳ| 鶹ýӳ 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.
New mineral from Earth’s lower mantle surfaced as diamond inclusion; study led by UNLV geochemist Oliver Tschauner.
UNLV geochemists have discovered a new mineral on the surface of the Earth. But they say it shouldn’t be here.
UNLV geochemists have discovered a new mineral on the surface of the Earth. There’s just one catch: it shouldn’t be here.
‘Davemaoite’ usually only exists in the deep Earth. Plus, homicide is a top cause of maternal death in the United States, and what scientists think of the Glasgow Climate Pact.
Newly discovered mineral, named davemaoite, was found encased within a diamond.
Researchers thought the mineral was impossible to find on Earth's surface.
The rare mineral, long hypothesized but never seen, was recovered from a diamond that emerged from the Earth's lower mantle.
