On the basis of grain size and matrix characteristics, three types of sedimentary rocks related to coquina can be distinguished: coquinite, microcoquina and coquinoid limestone. ... Microcoquina is also similar to coquina, but the shell particles are much smaller, under one millimeter in size. Coquinoid limestone is similar to coquina, ...When the oolitic grains reach a certain size, they are deposited on the seabed and consolidate into oolitic limestone. When the ooids are transported to a low energy zone, they form oomicrite. A typical oolitic limestone is located in the Yuntai National Geopark in Henan Province.

Lithographic limestone is a dense rock with a very fine and very uniform grain size. It occurs in thin beds which separate easily to form a very smooth surface. In the late 1700s, a printing process known as lithography (named after the stones used) was developed to reproduce images by drawing them on the stone with an oil-based ink, then using ...Jun 17, 2023 · Grain size: 0.06 – 2mm; clasts visible to the naked eye, often identifiable.
