Limestone: Rock Uses, Formation, Composition, Pictures
Limestone is a sedimentary rock that forms by both chemical and biological processes. It has many uses in agriculture and industry.
Aggregates
Mining crushed stone is more involved because the deposits are consolidated, meaning solid rock formations. The most common types of crushed stone come from deposits of limestone, dolomite and granite. To produce crushed stone, the massive formation first is drilled with a pattern of holes loaded with explosives by a licensed blaster.
