Clastic rocks may also include chemically weathered sediment. Clastic rocks are classified by grain shape, grain size, and sorting. Chemical sedimentary rocks are precipitated from water saturated with dissolved minerals.fossils (e.g. fossiliferous limestone) ooliths; pellets; In contrast, the chemically-precipitated limestones consist solely of crystalline carbonates (e.g. microcrystalline limestone).

"Fissile" means that the rock readily splits into thin pieces along the laminations. Uses of Shale Some shales have special properties that make them important resources. Black shales contain organic material that sometimes breaks down to form natural gas or oil.Table 5.3a. Rock densities and porosities. being in g/cm and or 0.23 when is in m/s or ft/s, respectively. The rule is valid for the major sedimentary rock types, but not for evaporites or carbonaceous rocks (coal, lignite). When a porous rock is saturated with a fluid, its density is given by the equation.This photograph illustrates two fossiliferous shale beds in the lower Bartolo Member of the Atrasado Formation (white arrows).

Sediment is deposited in a number of environments of deposition, by both moving air and moving water. Sedimentary rock identification is primarily based on composition. Texture will still be used but in a different sense than for igneous rocks.The McAbee fossil beds consist of 30 metres of fossiliferous shale in the Eocene Kamloops Group.
