The aquifer supplies limited amounts of water forFormation and Dakota Sandstone, respectively, so the mineral and energy resource potential for undiscovered resources of these commodities is low. There is no energy resource potential for undiscovered oil and gas because of the absence of known hydrocarbon source beds and because of the presence of a thin sedimentary cover that ...

The transition of sandstone into quartzite is a gradual process. 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.

The Dakota Sandstone (Cretaceous) in northeastern New Mexico is subdivided i to 3 intervals (Jacka and Brand, 1973).
