A 4.5-billion-year-old meteorite from northwest Africa has yielded one of the earliest minerals of the solar system.
Officially called krotite, the mineral had never been found in nature before, though it is a man-made constituent of some high-temperature concrete, according to study researcher Anthony Kampf, curator of Mineral Sciences at the Natural History 
"This is one that simply was not known in nature until we found it here," Kampf told LiveScience. "That's pretty dramatic."
