An earthy appeal, indoors and out. Limestone deposits exist in all continents of the earth. Despite the common and traditional reference to "travertine marble", travertine is really a type of limestone. It is actually the terrestrial (land) formed version of limestone, as opposed to the marine based formations of many other limestone varieties.

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.

Composition: Claystone is composed of clay-sized particles, while limestone is predominantly made up of calcium carbonate ( calcite or aragonite ). Limestone often contains fossils and has a higher mineral diversity. Hardness: Limestone is generally harder than claystone due to the presence of minerals like calcite.
