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.

In the uppermost part of the formation there is a persistent bed known as the Fencepost Limestone (Pl. 6D). This bed causes an easily identifiable double-pronged "kick" on electric logs, which can be traced from well to well as far as to Wyoming.The Gage Shale Member is mostly clayey shale, but calcareous fossiliferous shale and a minor amount of limestone occur in the upper part.

Glacier - A glacier is a mass of ice that persists from year to year and moves or flows over land under its own weight.Shale is a fine-grained sedimentary rock that forms from the compaction of silt and clay-size mineral particles that we commonly call "mud." This composition places shale in a category of sedimentary rocks known as " mudstones ." Shale is distinguished from other mudstones because it is fissile and laminated.
Fossils are rare in the shale and either are replaced by pyrite or are preserved as a film of graphite. Black shales occur in thin beds in many areas at various depths. They were …Shale forms from the pressure of layers of sediment compressing bits of silt that settle into the clay on the bottom of bodies of water.
