Re: World's Largest Impact Found In South Africa



This is an old story isn't it?  I have many references citing the Vredefort
as possibly an impact structure.

World's Largest Impact Found In South Africa
SpaceDaily
October 5, 1999

Johannesburg (AFP) October 5, 1999 - South African geologists have 
identified a crater in central Free State province to be the oldest and 
largest in the world caused by the impact of a comet or an asteroid, 
scientists said.

World renowned University of the Witwatersrand (Wits) 
paleo-anthropologist Philip Tobias told a public lecture on human 
evolution here that the Vredefort crater, which is between 250 and 300 
kilometers (150 and 190 miles) in diameter, was long thought to be of
volcanic origin.
