Skolithos
Vertical burrows and escape traces are dominant in active channels (Skolithos ichnofacies). During channel abandonment or periods of low discharge, meniscate burrows are emplaced in channel deposits (Scoyenia ichnofacies) commonly crosscutting the previous suite. If channel reactivation is produced, the Skolithos ichnofacies is re-established ...Contact skolithos geological consultancy stockport, providing sedimentological, stratigraphical and petrographical services. top of page.

The Hanneh Member (Cambrian Stage 5) of the Burj Formation and the Umm Ishrin Formation of Jordan represent a transgressive-regressive succession that contains twenty-eight ichnotaxa, including vertical burrows (Arenicolites isp., Diplocraterion isp., Gyrolithes polonicus, Rosselia isp., Skolithos linearis, escape trace fossils), horizontal simple burrows and trails (Archaeonassa fossulata ...Oct 26, 2010 · The presence of contrasting ichnofabrics within a single early Cambrian sand-sheet complex illuminates how the colonization trends of suspension and detritus feeders were controlled by factors specific to the various sub-environments. Gog Group, Ichnofabric, Lower Cambrian, Pipe Rock, Rosselia, Skolithos.

Skolithos pipe rock and associated ichnofabrics from the southern Rocky Mountains, Canada: colonization trends and environmental controls in an early Cambrian …Skolithos (formerly spelled Scolithus or Skolithus[1]) is a common trace fossil ichnogenus that is, or was originally, an approximately vertical cylindrical burrow. It is produced by a variety of organisms in shallow marine environments globally and appear as lineated features in sedimentary rocks.[2]Via Macclesfield. Starting with a PhD, sponsored by Norsk Hydro’s Research Centre in Bergen in 1988, Andrew has been actively working on paralic, shallow marine and continental clastic reservoirs for the best part of 28 years. This experience has been global as he has been fortunate to study such giant fields as Ghawar in Saudi Arabia ... …

The lowermost interval of a sandy tidal-flat parasequence is characterized by sharp-based sandstone, which overlies the truncated mud-flat deposit of the previous parasequence. This high-energy flooding surface is commonly delineated by firmground Skolithos of the Glossifungites Ichnofacies (Fig. 17).The trace fossil distribution generally confirms this subdivision, with Skolithos and Arenicolites being confined to shoal sand facies (archetypal Skolithos ichnofacies of upper shoreface) and other trace fossils occurring in lime muds and tempestites (archetypal Cruziana ichnofacies of lower shoreface). Nonetheless, the detailed analysis of ...Add to Citation Manager.

The occurrence of Skolithos in the Cardium Formation (Turonian) provides ichnofossil evidence for opportunistic behavior in the geological record. The Cardium Formation in the Pembina oilfield area of west‐central Alberta consists predominantly of mudstones. which coarsen upward into fine‐grained sandstone beds; the sequence is interpreted ...Skolithos ichnofacies. This ichnofacies is generally developed in shallow water in the nearshore environment. It is typical of higher energy conditions associated with well-sorted, shifting sands. Deep, vertical, and U-shaped tubular burrows characterize the ichnofacies. The resemblance of Skolithos to organ pipes gave the Cambrian rocks of NW ...
