Pierre shale
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. Shale is a sedimentary rock.The Pierre Shale is a good target for electrical exploration because of the contrast between the relatively high resistivity sand/clay mix of the alluvium and the consistently low resistivity of the shale. SCHLUMBERGER SOUNDING Schlumberger sounding is a geophysical technique that uses variations in the electrical

In a broad sense, "nautiloid" refers to a major cephalopod subclass or collection of subclasses ( Nautiloidea sensu lato ). Nautiloids are typically considered one of three main groups of cephalopods, along with the extinct ammonoids (ammonites) and living coleoids (such as squid, octopus, and kin). While ammonoids and coleoids are monophyletic ...Nov 10, 2020 · Deposition began about 75 million years ago with the formation of the Pierre Shale, the base of the geologic formations in the park. 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).
Dolichorhynchops is an extinct genus of polycotylid plesiosaur from the Late Cretaceous (early Turonian to late Campanian stage) of North America, containing three species, D. osborni, D. bonneri and D. tropicensis, as well as a questionably referred fourth species, D. herschelensis.

Well-preserved fossils are somewhat rare in the Pierre Shale of Colorado, but a location known as Baculite Mesa near Pueblo is one of the exceptions. The Pierre Shale at Baculite Mesa ranges from fine shades of gray to light beige/tan.Pierre Shale In this area, the Pierre shale is a loose muddy shale, punctuated outcrops of hard rock.
