Some common nonmineral constituent terms are: "tuffaceous," "cherty," "fossiliferous," "crinoidal," "coralline," "clayey (argillaceous)," "silty," "shaly," "sandy (arenaceous)," and "conglomeratic." Minor mineralogy should follow the nonmineral composition and should be restricted to one conspicuous mineral not implied in the root name.Fossils are rare in the shale and either are replaced by pyrite or are preserved as a film of graphite.
