Minerals

Well...sorta. It's a stone that looks a LOT like the red Mexican granite on my mum's kitchen counter. But apparently it's supercool cos it has copper embedded in it! Look closely.

This is some very special formation thingy, with three stripes...if my mum does show up and comment she'll tell us what it is.

The last is banded iron - which I think results from the iron in the ore melting in the thingy with the hot rocks...
