Researchers have found the oldest piece of the Earth’s crust that has been discovered yet, a 4.4 billion-year-old piece of zircon. The crystal helps confirm a theory about when the Earth’s crust formed and provides new insight into planet formation and how a planet can become habitable.
The research was led by John Valley, from the University of Wisconsin-Madison, and the crystal was pulled from the Jack Hills rock outcrop in Australia, an area well-known as a source for zircons. Valley and his team determined the mass of iron atoms in the zircon sample to determine the age and temperature history of the crystal.
