Granite rock formations - Murphy's Haystacks, Mortana - South Australia

Eyre Peninsula's Murphy's Haystacks are among the oldest rocks in Australia but they're slowly eroding away.
They are of a tumulus form of weathered granite outcrop. They are made of a pink, massive, coarsely equigranular rock consisting mostly of quartz and orthoclase. Their appearance may be due to a combination of erosion by underground rainwater and then by subsequent weathering after they were exposed. Most of the pillars emerge without a break from the underlying granite. Their structural base may be of orthogonal or vertically-aligned sheet jointing.
The rock's shapes are believed to be 1.6 billion years old, as the rock itself was believed to be 3 billion years old.
"The actual granite itself is very ancient, but the form of the Haystacks is much more recent, so you can probably go back to the time of the dinosaurs and the weathering of the landscapes."
