COMET TURNED SAHARA INTO GLASS 23 MILLION YEARS AGO

 

Egyptian pebble filled with DIAMONDS reveals comet that turned Sahara into glass 28 million years ago

Clues of the impact were also found in Libyan desert glass in the Sahara

Glass was created after comet heated the sands of the desert to 2,000°C

A magnificent specimen of the glass can be found in Tutankhamun's brooch

The first evidence of a comet impact on Earth has been found in a mysterious black Egyptian pebble filled with diamonds.It created huge amounts of yellow silica glass - also known as Libyan desert glass- which today lie scattered over a 6 000 square kilometre area in the Sahara.

 

‘Comets always visit our skies – they’re these dirty snowballs of ice mixed with dust – but never before in history has material from a comet ever been found on Earth,’ said Professor David Block of Wits University, who led the research.

 

As well as the glass, the impact produced microscopic diamonds.
