Deposition ended about 28 million years ago with the Sharps Formation, the uppermost unit of Badlands stratigraphy. Erosion is the process of rocks gradually wearing away. On the other hand, Cerasi et al. conducted a series of uniaxial creep experiments on Pierre shale saturated with HCl acid to simulate the low pH environment upon injecting CO 2. Their study revealed that the creep rate increased upon exposure of the shale specimens to the acidic environment (Cerasi et al. 2017).

The Pierre Shale and time-equivalent marine units in the western interior United States contain 28 ammonite range zones. The ammonites show such rapid evolution and such wide geographic ...

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. The compressed clay and silt become shale over time.
