The palaeoenvironments of the upper Palaeozoic succession in the eastern foot slopes of the Northern Galala Plateau, west of the Gulf of Suez, Egypt, are interpreted based on a detailed study of the sequence-stratigraphic framework, sedimentary facies and trace fossils. The upper Carboniferous–lower Permian Aheimer Formation has been studied in its type section exposed in Wadi Aheimer. Three ...The Lower McMurray fluvial successions have root structures but lack animal traces, with the exception of extremely rare Planolites, which occur in perched lacustrine sediment (Hein et al., 2000, Hein et al., 2001), and insect burrows in pedogenic mudstone in equivalent oil-sand deposits in northwestern Saskatchewan (Ranger et al., 2008).Status and Trends of Water Quality Worldwide. Y. Shevah, in Comprehensive Water Quality and Purification, 2014 1.4.6.2.2 Use of brackish water. Brackish water is defined as having a chloride content more than 400 mg l −1 or an electrical conductivity greater than 1.5 dS m −1.Large quantities of brackish groundwater exist throughout the study area, generally as part of complex groundwater ...

The restudy of Planolites ophthalmoides Jessen, 1950 reveals that this ichnotaxon is basically identical with the ichnospecies Siphonichnus eccaensis Stanistreet, le Blanc Smith and Cadle, 1980 and therefore must be regarded as its senior synonym and the type ichnospecies of Siphonichnus, resulting in the valid name Siphonichnus …Specimens of Planolites, a tubular ichnofossil, from the Harkless Formation (Cambrian of Nevada) are commonly rimmed by thin layers of limonite, a probable pseudomorph after pyrite, suggesting that bacterially induced biomineralization played a key role in the preservation of the burrows. Organic material secreted by a vermiform, infaunal tracemaker is inferred to have formed the substrate for ......

The formation dates to the Stage 3 of the yet-to-be-ratified Cambrian Series 2; the lower portion base of the formation and the youngest Lagerstätte beds date to the Nevadella trilobite zone (= Laurentian Montezuman stage), with higher beds dating to the Olenellus trilobite zone (= Laurentian Dyeran stage), making the formation the same age as the Sirius Passet and just younger ...

(See Fig. 5 for the key to the sedimentary structures and symbols.) from publication: Challenges in characterizing ...The most common sedimentary rock type is known as shale, made up of tiny silt or clay particles cemented together. Tiny particles are easily carried along by moving water. Thus, in uniformitarian thinking, shale particles take an inordinate amount of time to fall through a column of water and settle on the bottom, even when the water is … clean up communityeasy casket osrs In the correlative Vanrhynsdorp Group in South Africa, a similar pattern is observed.
