EESC 121: Earth ...This equation indicates that a straight line with unity slope will be achieved by plotting log (RQI) versus log (φ z).The RQI value would equal the FZI value at φ z = 1 (y-intercept of the line). As observed in Fig. 1, samples with different FZI values will lie on other lines parallel to this line.The samples lying on this line have identical pore throat size …Olivero & Atrops (1996) introduced a new name for these alternations in the transition area, "calcaires à Zoophycos" du Verdon Formation, and restricted its use to the Zoophy cos-bearing part of ...

The Glossifungites Ichnofacies was erected by Dolf Seilacher (the father of modern ichnology) in the midnineteen sixties to encompass burrows excavated into firm or compacted substrates.The Zoophycos occurs in sediments deposited during the transition from ice-free open marine conditions to a fluctuating subpolar ice sheet suggesting that the Zoophycos-producing ani-mal colonized the seafloor during this transition. The 1.5m thick interval in which Zoophycos has been found (351.93–353.38 mbsf) occurs in 17.24m thick unit, Zoophycos is a characteristic trace fossil in the Mississippian in the Alborz Basin deposits of north Iran, and is described for the first time in the Mobarak Formation. The vertical distribution ...
Zoophycos is thought to be formed by moving and feeding marine polychaete worms and can extend for up to 1 m, both horizontally and vertically in the rock. Zoophycos are an important part of the bedding plane waviness at 0.5-1 m scale, and thought to probably contribute greatly to the engineering stability of the rock mass. ...Trace fossil Zoophycus on the bedding plane of a bioclastic wackestone at ~76.4 m. F. Intraclastic floatstone with subangular lime mudstone intraclasts at ~63.2. G. Bioclastic rudstone at −4.85 m, containing various corals and a brachiopod shell with a boring (arrow). H.

Several ichnogeneric names are available for this array of forms, but as the necessary revision has yet to be undertaken, the ichnogenus Zoophycos will be used for the material published herein. The spiral forms may reach diameters exceeding 1 m.Trace Fossils - West Virginia University

The comparison between shallow- and deep-marine diatomites indicates a regressive sequence in the deep diatomites, with abundant Chondrites and Zoophycos at the base of the succession grading downward into Thalassinoides-dominated trace fossil assemblage in the uppermost part, which is similar to the shallow-tier trace fossils of the two ...Several oil shale beds, over 10 m thick, occur at the base of the first member of the Upper Cretaceous Qingshankou Formation (K2 qn 1) in the Songliao Basin. They act both as excellent source rocks for conventional oil and as potential oil deposit for shale oil production. Here we combine micropaleontology with organic geochemistry to investigate …In this study, we focused on the definition of behavioral complexity in the trace fossil Zoophycos to explore its paleo-environmental significance.
Its fossil content is characterized by the presence of the brachiopod, crinoid’s meadows and Zoophycos. c) The upper interval (upper part of the Tinerhir Formation) is dominated by sandstones sometimes with carbonate nodules, alternating with pelitic-sandstone or calcareous beds, and is characterized mainly by an abundance of …Zoophycos is a large, distinctive trace fossil that is found in marine deposits throughout the Phanerozoic, but has rarely been reported from New Mexico. It has been usually interpreted as the deposit-feeding trace of a marine worm. Zoophycos also gives its name to an archetypal ichnofacies characterized by Seilacher in 1967 as being deposited in deep or at least dysaerobic bottom water.

KF-11: thrombolitic–stromatolitic boundstone with clotted fabric. Full size image.Zoophycos is an ichnogenus thought to be produced by feeding worms. Zoophycos is found in deep marine muds and sands, often between turbidite beds. It is known from both the fossil record and deep sea sediment cores.
