The member is usually deeply weathered but appears not to have been strongly lithified at any stage. St. John Facies: Flysch-like marine muddy fine sandstone with minor laminae of carbonaceous matter. Usually moderately well lithified.The Muddy Sandstone, although commonly less than 100 ft thick, is one of the most complicated formations in the Powder River basin. Utilizing an integrated sedimentologic and stratigraphic analysis of outcrop, core, and well logs, the Muddy can be divided into six isochronous members. The recognition of two widespread, subaerial unconformities ...

An integrated subsurface and outcrop study of the Muddy Sandstone in the western Wind River basin was conducted in order to determine (1) if Muddy paleovalleys and are present there, (2) if potential for stratigraphic traps exists, and (3) if source rocks of sufficient quality and maturity are able to charge the Muddy reservoirs.Greatest gas production from the Muddy (J) Sandstone in Wattenberg field occurs (1) from within the most permeable and thickest intervals of Fort Collins Member delta-front and nearshore-marine sandstones, (2) to a lesser extent from the Horsetooth Member valley-fill channel sandstones, (3) in association with a large thermal anomaly that is ...The sandstones are mainly sublithic arenite with angular to subrounded, moderately sorted grains, embedded in muddy matrix.

Almon; apartments for rent under dollar1300 in huntington beachalcohol power Mud content increases upwards in the facies S4 beds, and their upper contacts exhibit dewatering structures, with injections of muddy sand into the overlying sandstones (Figs. 7 G). The S4 facies is interpreted to represent unlithified, saturated muds and fine-grained sands upon which sands were deposited rapidly.Sandstone Basics. Sandstone is a type of rock made from sediment — a sedimentary rock. The sediment particles are clasts, or pieces, of minerals and fragments of rock, thus sandstone is a clastic sedimentary rock.
