A team of geologists from Curtin University has discovered unequivocal evidence for a hypervelocity meteorite impact 3.47 billion years ago (Archean Eon) in the center of the Pilbara region in Western Australia.
The impact of Theia would in my unscientific opinion be a far better suspect. It both tore away lots of lighter material that would have made the crust too thick for continental drift, while adding to and remixing the remainder.
