South Africa's Vredefort Crater discovery's impact echoes still today

Desmond Moser never gives up. Br>Twenty years ago, the now Western Earth Sciences professor first visited the heart of South Africa's Vredefort impact crater, locating what he believed to be some of the only remains of a magma sea created more than 2 billion years ago in a 300-kilometre-wide crater.
He published his finding in 1997 in the journal Geology and awaited praise from peers.

Earth's Oldest and Biggest Crater Yields New Secrets

Geologists say they've discovered rocks long thought vanished, the youngest remains of the oldest and biggest impact crater on Earth.
In the abraded heart of South Africa's Vredefort impact crater lurk striking green-black rocks, some of the only remnants of a magma sea that once filled the gaping crater, according to a study to be published this May in the journal Geology. Until now, geologists thought nearly all of these "impact melt" rocks were lost to time. Some 10 kilometers of Vredefort crater has worn away since it was whacked open 2.02 billion years ago.

The South African government and landowners of the Vredefort Dome, site of meteorite impact, have signed a Memorandum of Agreement, taking the site a step closer to becoming a new World Heritage Site and protected under South African law.
The signing of the Memorandum of Agreement will pave the way for the proclamation of the area as a heritage site and appointment of a management authority which will serve as a precursor for the development of an integrated management plan.

Two billion years ago a meteorite 10km in diameter hit the earth about 100km southwest of Johannesburg, creating an enormous impact crater. This area, near Vredefort in the Free State, is now known as the Vredefort Dome.

It was voted South Africa's seventh World Heritage site at Unesco's 29th World Heritage Committee meeting in Durban in July 2005.

Vredefort Dome is the world's largest and oldest known meteorite impact site.

The Free State has many geological wonders to be explored. Shaped by time, these striking features are as visually awesome as they are significant to the history of the world. Two of the Free State's top geological attractions are the cliffs of the Golden Gate Highlands National Park and the Vredefort Dome.

Most of us know that Vredefort Dome has something to do with a meteorite that hit Earth a very long time ago, but not much else. Is the crater worth a visit? Leon-Ben Lamprecht travelled to Parys, the unofficial capital of the Vredefort Dome, and found there are lots of activities to keep holidaymakers happy.

To the amazement of nature lovers, tour planners and scientists at home and abroad, there is now talk of delisting the Vredefort Dome as a Unesco World Heritage Site (WHS). The Dome is one of eight sites in SA designated by Unesco (the United Nations Educational, Scientific and Cultural Organisation), including another troubled site, Robben Island, but also including such favourites as the Drakensberg, Mapungubwe and the Cape Floral Kingdom. More are likely to be added as time goes on - unless the country embarrasses itself to such an extent that Unesco simply walks away.
