Photographer’s Note

This is another close up of a section of Uluru (Ayers rock).
Uluru is made from sedimentary rock called arkose sandstone, which is a coarse grained sandstone and mostly cotains a mineral called feldspar. The weathering of the rock gives it its red colour. The iron minerals in the rock are weathered by water and oxygen causing it to rust. The feldspar minerals within the arkose sandstone are also weathered and form clays, which contributes to the colouring. Here you can see where a piece of the rock has fallen off and the exposed underside has started rusting. Unweathered rock ia a grey colour.
