Limestone Mining
The next series of images depict various means by which limestone is quarried or processed, beginning with the oldest technologies and continuing up to the present. Below is an image of an old lime kiln, in which raw limestone (CaCO3) is converted to CaO, or lime. Lime has many more uses, especially in the chemical industry, than does limestone.

This most probably leads to an underestimation of gypsum removed from the site. The estimates of total quarried gypsum range from 1300 m 3 considering a flat upper surface, to 2000 m 3 supposing the surface topography was more convex. It is safe to think the real amount of quarried gypsum blocks should fall in between these two values. 5 ...

KGS--Kansas Rocks and Minerals--Kansas Rocks
Rocks formed by the evaporation of water are known as evaporites. This evaporation may take place either in shallow basins on the land or in the sea. However, the rocks that were laid down under the sea form the thicker and more widespread deposits. Kansas rocks formed in this way include deposits of gypsum, anhydrite, and common salt or halite.
Chalk | Encyclopedia MDPI
Chalk is a soft, white, porous, sedimentary carbonate rock, a form of limestone composed of the mineral calcite. Calcite is an ionic salt called calcium carbonate or CaCO3. It forms under reasonably deep marine conditions from the gradual accumulation of minute calcite shells (coccoliths) shed from micro-organisms called coccolithophores. Flint (a type of …
