For the first time, a high-pressure calcium silicate perovskite (CaSiO 3) has been identified as a naturally occurring mineral from Earth’s lower mantle, researchers report. The newly discovered ...

Silicon monoxide gas detected by JWST signals the sublimation and recondensation of silicate dust into crystalline minerals. These minerals combine into pebbles, the earliest building blocks of ...

"The process acts as a multiplier," Kanan said. "You take one reactive mineral, calcium oxide, and a magnesium silicate that is more or less inert, and you generate two reactive minerals." As a quick ...
