Muddy sandstone

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] .

Valley-fill deposits of the Lower Cretaceous Muddy Sandstone contain significant stratigraphically trapped hydrocarbon accumulations and are an important exploration target in Wyoming's Bighorn, Powder River, and eastern Wind River basins.The Chace Quartzite Member and the underlying upper Bonney Sandstone consist of cross-bedded and petee-laminated medium- to coarse-grained sandstones and poorly sorted muddy sandstones, and have been interpreted as supratidal to intertidal and a fluvial-dominated deltaic system, respectively (e.g., Gehling, 2000, Gehling and Droser, …

However, the secondary porosity seen in most ancient sandstones is the product of burial diagenesis. Permeability measures the ease with which a fluid flows through sediment or rock. The flow of fluid from one part of a rock to another, or from an aquifer to a bore hole, depends on the connections among pores and fractures.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.• • Casper Sandstone, Sand Creek, Albany County – – ongoing. • Phase 2 outcrop characterization (strat., structure), static modeling. • Uncertainty analysis of well interpretation, effects of upscaling on flow modeling results. • • Minnelusa Sandstone. • • Muddy Sandstone.

The picture above shows a muddy sandstone that was deposited on a flood plain. Dr. Alley's index finger in the lower left points along a ridge on the surface of the rock (shadows are to the lower right of Dr. Alley's finger and to the lower right of the feature he is pointing along; his finger is above the rock, so the feature must be a ridge and not a trough). Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20-25% of all sedimentary rocks.. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like uncemented sand, sandstone may be any color due to impurities ...
