That''s Missouri karst! The word "karst" comes from the German for the limestone region of Krs, Slovenia. Missouri is known as The Cave State because of its large number of caves. At least 5,700 caves are recorded in the Missouri Speleological Survey''s files in Rolla.
Missouri has a LOT of limestone quarries throughout the State. Many of these produce calcite crystals, and some also produce barite, pyrite or millerite specimens. The limestone and shale layers are also exposed in road cuts and streams, and some of these have geodes that .
Missouri limestone was at one time a prized building stone, though most limestone now produced in the state is used for aggregate (gravel) in roadbeds and for cement production. Limestone quarries can be found in 94 of the state''s 114 counties.
The First Magnesian Limestone Found on Femme Osage and Missouri bluffs, affords one of the most valuable of building materials, being generally of a rich buff color. Missouri College, in Warren county, Mo., is built of this material, which is quarried near by. Similar rock used for building in St. Louis was brought from Joliet, Ill.
Limestone and dolomite are the most common carbonate rocks that form solution caves. Gypsum is another common mineral formed in carbonate caves by cave making processes, though it is uncommon in Missouri caves.

A limestone member, the Hindsville Member, found mostly in western outcrops, is a crystalline, fossiliferous limestone that, when present ...
Jun 08, 2020· The most common sedimentary rocks in Missouri are limestone, its cousin dolostone, also known as dolomite, and sandstone. Chert is a common mineral associated with limestones and dolostones. Chert, of which flint is one type, is composed of the mineral quartz.
This valley is five miles wide, formed of limestone, and surrounded by hills of Jasper and traprocks. The attitude of the town above the Mississippi River, at St. Louis, is about 800 feet.
Limestone has many other uses. Powdered limestone is used as a filler in paper, paint, rubber, and plastics. Crushed limestone is used as a filter stone in onsite sewage disposal systems.

The Missouri and many of its tributaries cross the Great Plains, flowing over or cutting into the Ogallala Group and older midCenozoic sedimentary rocks. The lowest major Cenozoic unit, the White River Formation, was deposited between roughly 35 and 29 million years ago and consists of claystone, sandstone, limestone, and conglomerate.
Missouri offers rock climbers a diversity of geological exposures, ranging from a variety of sedimentary sandstone, conglomerates, and limestone layers to an array of igneous granite and rhyolite outcroppings. ...

Interbedded limestone and shale layers are typical throughout northeastern Kansas and northwestern Missouri. The Stoner, Eudora, and Capitan Creek are members of the Stanton Limestone, which is the uppermost bedrock formation across much of Johnson County, Kansas.
For well over a century, Missouri has hosted a robust limestone industry that has mined the rock and processed it into a variety of useful, if not vital, products for Missouri, the nation and the world. Limestone mining and utilization in Missouri began in the mid 1800s. The amount mined prior to 1920 is not known for certain.
