The ancient Earth may once have been completely covered in water, new research suggests.
In a study published in Natural Geoscience, researchers examined a chunk of ocean crust located in northwestern Australia’s outback that is approximately 3.2 billion years old.
The geologic site, called the Panorama district, provided clues about the chemistry of ocean water from billions of years ago.
It could also help scientists understand how and where single-cell organisms first emerged on earth.
Lead author Benjamin Johnson and co-author Boswell Wing analysed data from more than 100 rock samples across the terrain to search for two different isotopes of oxygen trapped in the stone.
Well, we all know about a time when it had only one continent (Pangaea), but I guess this goes even further !
Anyway, if the Earth wasn't completely covered in water at one point... then, I'm curious as to how oceanic rocks ended up in the middle of the Australian outback ?
