Pierre shale.

The Pierre Shale in this area is late Campanian to early Maastrichtian in age and contains the Baculites eliasi, B. baculus, and B. grandis Zones (Fig. 1B). This section is equivalent in age to the lower one-half of the upper unnamed shale member of the Pierre Shale at Red Bird, Wyoming, as described by Gill & Cobban (1966).

Its type locality is West bank of Missouri River near Bailey Island, which is in a Campanian/Campanian marine shale/shale in the Pierre Shale Formation of South Dakota. Environments: marine (1 collection), offshore (1) Age range: 84.9 to 70.6 Ma. Distribution:Stratigraphers have determined that seven lithostratigraphic units are exposed in the study area: Chuar Group, Tremadoc Formation, Labrador Formation, Percha Shale, Salem Limestone, Paradox Formation, and Pierre Shale. The ages of the units have not yet been determined. To that end, fossils have been collected from nine stratigraphic horizons.And, finally, Tylosaurus neumilleri and Tylosaurus pembinensis were described from the middle Campanian of the Pierre Shale of South Dakota and Manitoba, respectively (Nicholls 1988;Martin 2007 ...Stress-Strain behavior for a shale sample.

Outcrop Pierre Shale is prepared for test by an initial drainage stage, in order to reduce the chemical potential of the pore water to a value more representative of buried rock. This enhances swelling when the shale is subsequently placed in contact with deionised water. Unlike vapour phase equilibration of chemical potentials, the stresses ...Member of the Pierre Shale.

Ammonite and nautiloid fossils have been prized from antiquity for their mesmerizing logarithmic spiral.

Shales are sedimentary rocks that consist of mainly reactive and non-reactive clay minerals (smectite, illite, kaolinite, chlorite, vermiculite) and other forms of minerals like quartz, calcite, feldspar, and many more (Lyu et al., 2015).However, in the presence of water, reactive clay minerals present within the shale formation have been faced with different challenges especially wellbore ...Fig. 3--A fresh exposure of lower Pierre-upper Niobrara lithology at location A. The bentonite beds marking the basal Pierre can be seen near the center of the picture. At least 24 separate bentonite beds are exposed in the Pierre Shale from the center to the top of the picture.The depth to the Pierre Shale along the transects ranged from about 2.4 to 20.3 meters, and mean and median depths were about 9.2 and 9.0 meters, respectively. The elevation of the Pierre Shale and thickness of unconsolidated deposits generally increased with land-surface elevation from south to north; however, some transects displayed ...The accuracy of the numerical solution is verified against an analytical solution in a homogeneous medium. An example shows that the proposed wave equation describes the constant-Q attenuation and velocity dispersion behaviour observed in Pierre Shale. Finally, we consider a plane-layer model and the Marmousi model to show how the new ...Pierre Shale In this area, the Pierre shale is a loose muddy shale, punctuated outcrops of hard rock. The terrain is quite barren. Water and sun protection is essential on hot days. Baculite Ammonoid This is typical of the baculite fragments which give this area its name. Baculite Mesa These hard rock formations poke up through the muddy shale ...In particular, shales often show strong elastic anisotropy that originates from the alignment and platy nature of its constituent minerals, as underpinned by laboratory measurements provided by many authors (e.g., Lozovyi & Bauer, 2019; Szewczyk et al., 2018; Vernik & Nur, 1992; Wang, 2002b ).Gastroliths from KUVP 129744.

The thickness of the Laramie-Fox Hills aquifer ranges from 0 to about 300 feet . The Laramie-Fox Hills aquifer generally consists of beds of fine- to very fine-grained sandstone or siltstone interbedded with shale.The lack of histological work may be in part complicated by taphonomic processes in some of the more prolific hesperornithiform sedimentary units. For example, several members of the Pierre Shale are characterized by calcite crystallization in the preserved bones, destroying histological information.

Underneath the Pierre Shale is the Dakota Sandstone, which is a source of water near the outcrop/subcrop areas on the western limb of the basin. In their respective outcrop areas, Denver Basin aquifers are unconfined (under water table conditions), whereas in the deeper parts of the basin, the aquifers become confined due to intervening layers ...

The Pierre Shale of Late Cretaceous age forms an impermeable base to the High Plains aquifer in much of Colorado.

The water is classified as a ...Cretaceous Pierre Shale is directly related to faulting in the underlying Precambrian rocks. The seismic data show fault displacements of as much as 70 ft in the Cretaceous sedimentary rocks at a depth of 2,130 ft; these displacements disrupt overlying rocks and appear to extend into the lower part of the Pierre Shale.Formations like the Marcellus Shale, the Rhinestreet Shale, Barnett Shale, Haynesville Shale, Woodford Shale, Pierre Shale, and Bakken Shale all onlap unconformities, suggesting that many black shales were deposited during a distal basin margin transgression onto a surface that may have been eroded during a previous sea level lowstand. 1.1.The test was conducted in Cretaceous-age Pierre Shale in central South Dakota, USA.
