Limestone makes a good cooking stone because it can be heated to 400500 C in a simple wood fire and, once good and hot, it holds heat for hours or even days. This property was used to cook food, especially within the layered cooking arrangements known as earth ovens. Because the Edwards Plateau is a vast expanse of limestone bedrock, suitable ...
Where limestone is an aquifer, there can be concerns that contaminants from the quarrying operations could escape into the groundwater. In many areas of the United States where limestone is found, it gradually dissolves in rainwater at the surface or in the nearsurface groundwater.
Mar 13, 2018· Formation. Limestone often forms from whole or pieces of a variety of organisms that contain calcium carbonate, such as mollusks, echinoids and corals. Most limestone beds form in marine environments where large deposits of organisms and carbonate precipitation build up over time.
A large rain event can weigh the soil down and can cause sinkholes to form. When the water level in the underlying limestone aquifer is depressed (due to drought or consumptive uses), the void spaces that once held water now are filled with air. Water provides some buoyancy and can keep the overlying geologic material stable.

Main Uses of Limestone: In Missouri, limestone of all kinds is used mainly for aggregate (aka "gravel") that is produced by crushing and screensizing limestone quarry rock.

They can also be found in the alluvial deposits (rocks and soil deposited by water) along rivers that flow from these areas. Minerals formed in Earth's mantle can find their way to the surface over the span of millions of years due to huge geologic effects such as tectonic plate upheaval.
Carboniferous limestone. One of the most famous Burren swallow holes is at Poulnagollum. One of the best examples of underground drainage is in the lowland area immediately to the east of the Burren, where waters from the Gort area bubble to the surface on the shore near Kinvara. Other features of the limestone lowlands are the turloughs,...

The shelly limestones of the Purbeck Beds, England, and the Sus marble, both of Mesozoic Era (from 251 million to million years ago), consist of masses of shells of freshwater snails embedded in blue, gray, or greenish limestone.
The resulting limestone commonly takes on the form of algae or groups of algae and may form irregular shaped and banded structures. Approximately half of the Pennsylvania and Permian limestones of eastern Kansas are at least, partially formed by algae. Particularly good exposures can be seen in Johnson County, Brown County and in the Flint Hills.
