Dark gray to black chert is called flint. • The carbon-rich rock formed from ancient plant material is called coal. Sedimentary rocks with non-clastic texture include fossiliferous limestone (above left), chert (above right) and coal (right). All three of these rock types can be found in Virginia.During diagenesis, water squeezes out of the pore spaces and forms Grains in the mass of the rock — the size of grains ranging from 0.001mm to 0.00004 inches. When grain formation takes place due to fossils, the size of fossils determines the shapes, patterns, and orientation of the grains.Embry has modified Dunham's classification and Klovan (1971) to include coarse grained carbonate s (above figure). In their revised scheme, a wackestone in which the grains are greater than 2mm in size is termed a floatstone and a coarse grainstone is called a rudstone.
