This "ultra-mature" beach sand marks the second inundation of the Ordovician; immediately above it is the St. Joachim dolomite, whose distinctive yellow "cotton rock" is considered by some to be a primary evaporative dolomite.

Dolomite Dolomite is one of the important minerals found in Missouri. The dolomite is made up of magnesium carbonate and calcium although it may also contain minor quantities of iron and manganese. Usually, the dolomite is found is a wide variety of colors such as pink, brown, gray, green, black, white and colorless.

Dolomite Exposed Cliffs occur along deeply dissected river valleys throughout the Ozark Highland. They occupy southerly and westerly aspects, and are mapped in complex with the Dolomite Protected Cliff ecological site. Soils are very shallow to limestone or dolomite. The reference plant community consists of scattered small trees, shrubs,

Label says "Dolomite. Tri-State area, Missouri". ... Dolomite probably exists in the locale, however, I have never observed a specimen labelled as dolomite, nor have observed what I believe to be dolomite. From the photo only - I say would likely to be Mahaska County calcite (multiple generations) – no reason to believe dolomite. ...

The Davis formation of Missouri was correlated by Ulrich (1932) with the Honey Creek limestone of Oklahoma which he had previously excluded from the Arbuckle (Ulrich, 1911, pp. 624, 642, 661, 666, pl. 27). Therefore, the Davis formation and the conformably underlying Bonneterre dolomite of Missouri also must be excluded from …

Since 1985, Missouri has had a solid framework for understanding our many terrestrial (land) natural communities. This system, sometimes called the "Nelson" system after its author, Paul W. Nelson, is an indispensable tool for anyone wanting to identify habitats, evaluate habitat quality, and make decisions about conservation and natural resources.
