There were these rocks
Big and small
Living on the mountains
Short and tall


They were black,
Brown and red
Forming on the hot,
Magma bed


Conglomerate.....
Limestone and Granite
These are some of,
My favourites.

Calamine.............
Pyrite and Bauxite
Are the best friends of
Haematite....


Bauxite is the
Ore of Aluminium
Today, half the world's energy
Comes from Petroleum..
