determining the general class of rock — igneous, metamorphic, or sedimentary — and then proceed to identify the minerals that make up the rock and then the texture of the rock. The mineralogy of a rock is a list of chemical compounds that form the grains in a rock, and the texture is the size, shape, and arrangement of those grains.
Hard rock. Hard rock quarries produce aggregates such as limestone and granite. They are usually large and can be very deep – depending on the geology – and the rock will be blasted and dug out at multiple different levels known as 'benches'. Sand & gravel. Sand and gravel quarries are shallower than rock quarries because the mineral ...
