The third sequence extends from the unconformity at the base of the Horsetooth Member of the Muddy Sandstone (J 2 unit of the J sandstone) to the base of Codell Sandstone. An erosional unconformity occurs at the base of the D sandstone in the eastern part of the Denver basin but is not present in the western Denver basin or Front Range outcrop. @article{osti_5878330, title = {Reservoir description and production history; Bell Creek field, Muddy sandstone, barrier island, and valley fill deposits}, author = {Tillman, R W and Szpakiewicz, M and Honarpour, M M and Jackson, S R}, abstractNote = {Improved sedimentologic and stratigraphic reservoir descriptions of barrier-island sandstones and genetically related deposits allow better ...Granite changes into sandstone by means of weathering and erosion.

Bioturbated Muddy glauconitic sandstone (F-9) Sedimentology: This facies is composed of upper fine-grained glauconitic sandstone. The base part may contain light steel gray to blue mud beds. These bluish-gray mud beds may appear interlaminated with glauconitic sandstone when not homogenized by bioturbation. The abundance of silt …logs were used to differentiate between sandstone and shale; however, in the SWWP the spontaneous potential response commonly is greatly subdued in some sandstone intervals and shows little curve deflection. In areas of greater drilling density, logs from wells located between control wells on theThe sharp contact between the two fills and thick muddy sandstone caps in the upper fills are interpreted to be related to the partial plugging of the channel by the debrite, which resulted in the local diversion of the axis of general sediment transport and ponding of the tail part of the transiting flows.Dakota Formation (Nebraska) Show map of Nebraska. The Dakota is a sedimentary geologic unit name of formation and group rank in Midwestern North America. The Dakota units are generally composed of sandstones, mudstones, clays, and shales deposited in the Mid-Cretaceous opening of the Western Interior Seaway. [7]

The "D" sandstone overlies the Muddy ("J") Sandstone and production is often reported commingled with the "J".Because the lower Muddy was deposited during a southeast to northwest regression, the sandstones are progressively younger toward the northwest. However, the overlying nonmarine upper Muddy thickens northwestward, causing the underlying regressive sandstone to appear to be stratigraphically lower and, hence, older in that direction.
