Limestone is a sedimentary rock composed principally of calcium carbonate (calcite) or the double carbonate of calcium and magnesium (dolomite). It is commonly composed of tiny fossils, shell fragments and other fossilized debris. These fossils are frequently visible to the unaided eye on close examination of the stone surface, however …

Limestone mining and utilization in Missouri began in the mid 1800s. The amount mined prior to 1920 is not known for certain. Since that time, however, reliable statistics do indicate that 3.1 billion short tons of limestone having a present value of about $17.5 billion have been mined in Missouri from 1920 to present.
