.... During regressive depositional phases in the Missourian (Late Pennsylvanian), siliciclastic sediments were transported into Kansas mainly from the southeast. The five members of the latest Missourian Stanton Formation (in ascending order: Captain Creek Limestone, Eudora Shale, Stoner Limestone, Rock Lake...

...R. M. Joeckel Abstract Enigmatic structures in the shape of inverted rounded cones are very common in a discrete horizon of the upper Stoner Limestone Member (Stanton Limestone Formation, Lansing Group, Upper Pennsylvanian) in southeastern Nebraska. These structures are 100–300 mm in diameter...

... of skeletal calcilutite. The overlying Eudora Shale Member averages 6 ft in thickness in northern Kansas, pinches out locally over the mound complex, and thickens abruptly to 70 ft south of the mound. The Stoner Limestone Member contains two algal-mound complexes. In central Anderson County the member...

...Figure 7 Rock Lake Shale paleosol (SB 2) at Ash Grove Quarry, Louisville, Nebraska (location A in Fig. 4 ). Aridisol-like paleosol with comparatively shallow carbonate nodule horizon (Bk) overlies weathered Stoner Limestone Member, upper 25–40 cm of which has pervasive microkarst under...

..., and the upper arrow points to the Haskell Limestone, which is generally thin in interfluvial areas. Units on the scale are 15 cm. (b) Basal sequence boundary near the middle of the trunk paleovalley. The top of the hammer rests on the boundary between the Stoner Limestone Member of the Stanton Limestone below...

... cross-bedded, yellowish to red sandstone. Unit 2 is discontinuous bituminous, thin-bedded limestone, in places associated with gypsum, attaining a thickness of 15 feet, and named the Pony Express limestone member of the Morrison formation. Unit 3 is sandstone or sandy beds about 20 feet thick here named...

... ( Hooker et al . 2004 ), which calibrates well with the biostratigraphy. The 2‰ positive shift in freshwater δ 18 O values, recorded in rodent tooth enamel by Grimes et al . (2005) between the Osborne Member and the Bembridge Limestone, has been misinterpreted by Gale et al . (2006 , p. 413...

... marlstone (Siliceous Marlstone member; Fig. 4 ). At the boundary between the Jurassic and Cretaceous, a major paleoceanographic change occurred and siliceous sedimentation was replaced by carbonate-rich pelagic sedimentation dominated by calcareous phytoplankton. These pelagic limestones, ubiquitous...

... (mainly till), 16 m of shale and siltstone, a 27-m–thick sandstone aquifer, and about 174 m of low-permeability shales, siltstones, clays, thin coals and limestones, and thin sandstones. The aquifer, the Mount Carmel Sandstone, is moderately permeable (around 10 −6 m/s) and consists of two sandstone...

... the Thames and through the lock at Limehouse Reach into the Regent's canal. He is passionate about steam, regularly visiting the Great Dorset Steam Fair, and is a life member of the Swanage steam railway in Dorset and the mid-Hants steam railway (Watercress Line) in Hampshire. Peter Fookes is pre...

... approaches that use machine learning to classify sedimentary facies from multivariate data sets. Most attempts have focused on classifying bulk sedimentary facies (e.g., mudstone, sandstone, marl, and limestone) and have had varying success when models are validated against observed lithofacies ( Dubois et...

... of limestone and sandstone. It includes members in the upper part of the Chinle Formation, a lower member (Rock Point Member) of the Wingate Sandstone, and the upper two members of the Dolores Formation or, locally, the entire Dolores Formation ( Fig. 1 ). The sandstone sequence is composed of light-brown...

... was performed using stratigraphic data from the Pennsylvanian succession containing floodplain limestones of the Stewart Quadrangle of Athens County in Ohio (USA). Limestone volumes for six limestone units (Upper Pittsburgh, Fishpot, Sewickley, Benwood/Arnoldsburg, Uniontown, and Waynesburg limestones) were...

... pentes de pergélisol ont accru les taux de sédimentation dans le bassin. [Traduit par la Rédaction] Middle Ordovician Bay Fiord Formation bedrock, regionally composed of dolomite and gypsum with limestone, shale, and siltstone underlie the lake. To the southwest and west of the lake...

..., siltstones, limestones, coals and sandstones. A generalized stratigraphic column for the lower part of the Monongahela group is shown in Figure 2. Over much of the basin, limestones and calcareous shales overlie the coal, but rapid facies changes produced channel sandstone roofrock in some areas ( McCullogh...

... of pale red, dominantly non-bentonitic siltstone and light greenish gray and pale red limestone. The Church Rock member is noticeable as a reddish or brownish siltstone and sandstone unit lying above the limestones of the Owl Rock member. The Chinle formation is a brightly colored slope-forming unit...
