4.5 billion-year-old meteorite yields new mineral

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 human-made constituent of some high-temperature concrete, according to study researcher Anthony Kampf, curator of Mineral Sciences at the Natural History Museum of Los Angeles County.

"This is one that simply was not known in nature until we found it here," Kampf told LiveScience. "That’s pretty dramatic."

The meteorite containing krotite is called NWA 1934 CV3 carbonaceous chondrite. Chondrites are primitive meteorites that scientists think were remnants shed from the original building blocks of planets. Most meteorites found on Earth fit into this group.

The mineral, a compound of calcium, aluminum and oxygen, needs temperatures of 2,732 degrees Fahrenheit (1,500 degrees Celsius) to form, supporting the idea that it was created as the solar nebula condensed and the planets, including Earth, were formed, the researchers say.

The tiny mineral sample — just 0.2 inches (4 millimeters) long — came from a grain in the meteorite dubbed "cracked egg" for its appearance. In addition to krotite, the cracked egg grain contains at least eight other minerals, one of which is new to science, the researchers say.

Studying this mineral and other components of the ancient meteorite is essential for understanding the origins of the solar system, the scientists say.
