Sorry about the delay folks and I'm a bit bleary-eyed at the moment but I lifted this info from
www.pacificislandtravel.com/australia/northern_territory/uluru.html
because I am a bit tired, and I need a spell checker, missed Gondwanaland the first time around.
There is some scientific disagreement about the origins of Uluru. The most widely held theory is that both Uluru and Kata Tjuta are remnants of a vast sedimentary bed which was laid down some 600 million years ago. The bed was spectacularly tilted so that Uluru now protrudes at an angle of up to 85°. The rock is actually grey but is covered with a distinctive red iron oxide coating.
Also there is a link to my town, don't know how accurate it is, didn't get a chance to read it.
Bedtime reading for you all.
