Trap Rock: Dark igneous rocks used to make crushed stone

What is Trap Rock? Trap rock is a name used in the construction industry for any dark-colored igneous rock that is used to produce crushed stone. Basalt, gabbro, diabase, and peridotite are the most common rock types referred to as trap rock. "Trap rock" is not a geological term that you are likely to learn about in a geology course or read about in a geology textbook.

Bauxite - Sandatlas

Bauxite is a result of intense leaching in a hot and humid climate with alternating wet and dry seasons and good downward drainage. The climate promotes vegetation that provides organic acids, which help to dissolve rocks in percolating water that carries more soluble components away, leaving only aluminum and also often iron as the least mobile common ions behind.

Bauxite is an aluminium ore found in deposits around the world. Once the ore is mined out of the ground, the red bauxite rock is crushed and dissolved into a white alumina powder, using what is known as the Bayer process. This alumina powder is then smelted into aluminium metal. Australia is the world's largest producers of bauxite.
