Limestone - Sedimentary rocks

Limestone is a very common sedimentary rock consisting of calcium carbonate (more than 50%). It is the most common non-siliciclastic (sandstone and shale are common siliciclastic rocks) sedimentary rock.Limestones are rocks that are composed of mostly calcium carbonate (minerals calcite or aragonite). Carbonate rocks where the dominant carbonate is dolomite (calcium magnesium carbonate) are ...

Lithographic Limestone: A dense limestone with a very fine and very uniform grain size that occurs in thin beds which separate easily to form a very smooth surface. In the late 1700s, a printing process (lithography) was developed to reproduce images by drawing them on the stone with an oil-based ink and then using that stone to press multiple copies of the image.

How is limestone formed? | What is limestone? | .

Diagenesis is the process by which soft sediments turn to rock. Limestones originate as soft lime muds, shells and other fragments of the organisms living in the water. When these sediments are buried under others, they are compacted, the water is squeezed out of pore spaces and, in some cases, mineral grains are physically re-organised or chemically changed by the pressure.
