Confirmed: Earth's Oldest Rock In Australia 74
SpamSlapper writes "Australia's ABC Science reports that ancient zircon crystals discovered in Western Australia have been positively dated to 4.374 billion years, confirming their place as the oldest rock ever found on Earth, according to a new study. The research reported in the journal Nature Geoscience, means Earth began forming a crust far sooner than previously thought, following the giant impact event which created the Earth-Moon system 4.5 billion years ago."
Lots of Iron around there (Score:4, Interesting)
The area these are found are extremely high in Iron content. There are a number of high grade iron ore mines nearby. I wonder if there is any link between the high iron content and the formation of these rocks.
