Why the Pilbara is unique


This is a transcript of QuickTime movie (1.6 MB) recorded in the Pilbara in 2005. Dr Bruce Runnegar, Director of the NASA Astrobiology Institute, describes why the Pilbara is unique.

Transcript:

"The Pilbara is unique. Well there are two or three places on the surface of the planet that are about as unique, but particularly South Africa, the eastern side of South Africa, and the Pilbara in Western Australia.

"Both of these places have protected ancient sedimentary rocks from all of the effects of geology over long periods of time, three and a half billion years in fact. And so here we can find the best evidence on the earth for sedimentary rocks formed 3.5 billion years ago."
