For the first time, a high-pressure calcium silicate perovskite (CaSiO3) has been identified as a naturally occurring mineral from Earth’s lower mantle, researchers report.

Twenty years after their initial detection, enigmatic blasts from the sky are starting to deliver tentative answers, as well as plenty of science.

Until now, researchers believed the mineral could never be found on the earth's surface.

When Oliver Tschauner and colleagues dusted off a sample of volcano-ejected diamond found in a South African mine, they had no idea that they were holding the first-ever natural sample of a new high-pressure mineral from deep within Earth.

Study suggests that certain organic compounds in soil could make asbestos fibers more mobile.

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.

Physicist asserted scientific malfeasance in prominent result, but his paper itself is under fire.

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.
