4.4 billion year old crust. (http://news.nationalgeographic.com/news/2014/02/140224-oldest-crust-australia-zircon-science/)
I remember the crust on the bread back in school. It was so old, ... it was at least 4.4 billion years old.
Zircon crystals from the Jack Hills of Australia... reveal that continents arose just 160 million years after our solar system formed, much earlier than previously thought.
Did they take a trip to the planet Zircon?
"The results show that single grains of ancient zircon can yield a rich history, the implications of which date back to the very earliest history of our planet," says MIT's Samuel Bowring, in a commentary accompanying the study.
