The Dakota Sandstone rocks also contain coal, indicating that swamps were present. The contact between Dakota Sandstone and the Jurassic stratigraphic units is a clear change between the gray and brown Dakota rocks to the white and red Jurassic rocks, and a clear erosional surface separates the two..

Common sedimentary rocks include sandstone, limestone, and shale. These rocks often start as sediments carried in rivers and deposited in lakes and oceans. When buried, the sediments lose water and become cemented to form rock. Tuffaceous sandstones contain volcanic ash.

A single rock unit such as the Tuscarora Sandstone of the central Appalachians might fully fit the definition of quartzite in the parts of its extent where its quartz grains have been metamorphosed into a durable interlocking mass. It would be better called "sandstone" in other areas. Pores are open spaces within the rock mass. It gives porosity or permeability property to the sandstone rocks. Some sandstone types have tightly packed pores while some have loose binding between the clusters. The occurrence of pores defines the porous nature of sandstone.
