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.

Oolitic Limestone Sedimentary Rock - Mini Me Geology

Oolitic Limestone is a white, pink, red, gray or black sedimentary rock composed of mostly calcite oolites. Oolites form when layers of calcite are deposited around a sand grain or fossil piece and then rolled around in relatively calm water, making them round. Due to the calcite content, oolitic limestone will react to acids.

Most carbonate deposition also requires relatively warm waters which also enhance the abundance of carbonate secreting organisms and decrease the solubility of calcium carbonate in seawater. Nevertheless, carbonate rocks form in the deep ocean basins and in colder environments if other conditions are right.

The Clifton Down Limestone has a rich but low diversity fauna. The most notable feature is the abundant, partly silicified remains of the coral Siphonodendron ['Lithostrotion'] martini in the middle part of the formation. This coral-rich interval, named the 'Lithostrotion Beds', forms a conspicuous marker-interval that can be traced across the Mendip region.

What are the characteristics of fossil limestone

In most cases both the limestone AND the fossil will be dissolved by the vinegar (eg a crinoid in Carboniferous limestone), so no. However, some fossils (eg echinoderms in the Chalk) are silicified and in these cases dissolving the limestone in vinegar will expose the fossil in spectacular detail and in other cases the fossil will dissolve more slowly than the matrix, so yes. .
