Extensive canyons, excavated into the margins of the Levant Basin during the Oligocene–Miocene, are interesting case-studies for canyon fills in carbonate settings. The carbonate Pattish Formation, developed along the margins of the pre-evaporitic Messinian Beer Sheva Canyon in Israel, was investigated using both onshore seismic imaging and field data. The canyon has three main seismic facies of fill

Selective dolomitization, where certain carbonate components are preferentially dolomitized over others, can be significant in the overall dynamic context of the global magnesium cycle. Thus, the abundance of these components can modify the Mg balance between the ocean and sediments, thereby disrupting the Mg cycle in certain geological times. Selective dolomitization may be connected to the apparent

Permian–Triassic boundary microbialites (PTBMs) that formed directly after the end-Permian extinction in the South China Block are dominated by one structure, a lobate-form calcium carbonate construction that created extensive very thin (ca. 2–20 m thick) framework biostromes in shallow marine environments, effectively occupying the ecological position of the prior pre-extinction Permian reefs and/or

Age, microfacies and depositional environment of the Middle to Late Paleocene shallow-marine carbonates in the Sirt Basin of Libya (Upper Sabil Formation): “Are Intisar domal structures pinnacle reefs?” Facies (IF 1.8) Pub Date : 2021-08-28 Vršič, A., Gawlick, H.-J., Schlagintweit, F., Machaniec, E., Gharsalla, M.
In the central-eastern Sirt Basin, enigmatic Intisar domal structures host significant hydrocarbon accumulations. These structures have been commonly interpreted as pinnacle reefs/bioherms occurring in the open-marine basinal environment. Generally, pinnacle reefs/bioherms are mainly characterized by in situ carbonates. The current study challenges the Intisar pinnacle reef/bioherm model by examining

Stable carbon and oxygen isotope data of Late Ediacaran stromatolites from a hypersaline environment in the Tarim Basin (NW China) and their reservoir potential Facies (IF 1.8) Pub Date : 2021-06-26 Dongya Zhu, Quanyou Liu, Jingbin Wang, Qian Ding, Zhiliang He
The occurrence of Precambrian stromatolites is closely related to the ancient seawater composition and the evolution of life. It is also a potential oil and gas reservoir. In what kind of environment the stromatolites of the upper Ediacaran Qigebulak Formation in the Tarim Basin developed, and whether they constitute potential hydrocarbon reservoirs, remained unclear. Stromatolites occur in 1–5 m thick

Depositional setting and limiting factors of early Late Cretaceous glaucony formation: implications from Cenomanian glauconitic strata (Elbtal Group, Germany) Facies (IF 1.8) Pub Date : 2021-06-14 Markus Wilmsen, Udita Bansal
Cenomanian strata of the Elbtal Group (Saxony, eastern Germany) reflect a major global sea-level rise and contain, in certain intervals, a green authigenic clay mineral in abundance. Based on the integrated study of five new core sections, the environmental background and spatio-temporal patterns of these glauconitic strata are reconstructed and some general preconditions allegedly needed for glaucony

Applications of fossil taxonomy in palaeoenvironmental reconstruction: a case study of ostracod identification and diversity in Permian–Triassic boundary microbialites Facies (IF 1.8) Pub Date : 2021-06-10 Marie-Béatrice Forel, Stephen Kershaw, Alan R. Lord, Sylvie Crasquin
The value of taxonomy as a tool in palaeoenvironmental analysis depends on accuracy of determination of relevant taxa; in cases where taxa present unresolved problems of distinction (identification uncertainty and overlap), difficulties may exist in their application in facies studies. A prime example is found in ostracods of the Permian–Triassic boundary interval, considered here in sequences from

Reconstruction of tectonically disrupted carbonates through quantitative microfacies analyses: an example from the Middle Triassic of Southern Italy Facies (IF 1.8) Pub Date : 2021-06-03 Adriano Guido, Giuseppe Palladino, Matteo Sposato, Franco Russo, Giacomo Prosser, Mario Bentivenga, Adelaide Mastandrea
The main goal of the paper is the reconstruction of a Middle Triassic buildup cropping out in the central part of the Southern Apennines. Middle Triassic reefs of the western Tethys realm are well known in the Northern and Southern Alps. In contrast, few studies of the Anisian–Ladinian carbonate platforms of the southern Apennines are available, due to the diagenetic alteration and tectonic disruption

Palaeozoic stromatoporoid diagenesis: a synthesis Facies (IF 1.8) Pub Date : 2021-05-20 Stephen Kershaw, Axel Munnecke, Emilia Jarochowska, Graham Young
Palaeozoic stromatoporoids, throughout their 100-million + year history (Middle Ordovician to Late Devonian and rare Carboniferous), are better preserved than originally aragonite molluscs, but less well-preserved than low magnesium-calcite brachiopods, bryozoans, trilobites and corals. However, the original mineralogy of stromatoporoids remains unresolved, and details of their diagenesis are patchy

Alternations of thin-bedded limestone and shale, or ribbon rock, commonly occur throughout lower Palaeozoic carbonate successions; however, their formative processes are still unclear. In this study, we discuss the origin of the ribbon rocks of the upper Cambrian Hwajeol Formation, Korea, based on detailed microfacies analysis of a ~ 2-m-thick interval. Five sedimentary microfacies were identified:

Facies analysis of the Upper Ordovician Xiazhen Formation, southeast China: Implications for carbonate platform development in South China prior to the onset of the Hirnantian glaciation Facies (IF 1.8) Pub Date : 2021-03-10 Jino Park, Jeong-Hyun Lee, Kun Liang, Suk-Joo Choh
The Upper Ordovician Zhe-Gan Platform was a short-lived carbonate platform that formed near the northern margin of the Cathaysian Land of the South China Block. The Zhe-Gan Platform is less well understood than the adjacent Yangtze Platform due to the absence of detailed sedimentological study as well as the structural complexity of the area. The aim of this study was to reconstruct the Zhe-Gan Platform

Sedimentology and distribution of late quaternary calciturbidites and calcidebrites in the Mozambique Channel (Southwest Indian Ocean) Facies (IF 1.8) Pub Date : 2021-03-09 John W. Counts, Stephan J. Jorry, Natalia Vazquez-Riveiros, Lawrence A. Amy, Ewen Dennielou, Gwenael Jouet
Submarine gravity flow processes on carbonate platform slopes can lead to the deposition of calciturbidite and calcidebrite beds on the adjacent deep-water seafloor. Such deposits have been previously found to occur more frequently during sea-level highstands, leading to increased export of carbonates to the deep sea during interglacial periods. Here, we document a new occurrence of these types of

For the first time, we here report trace fossils of dung beetle brood balls (Coprinisphaera ichnogenus) in late Pleistocene sediments from Somalia. The sediments containing these traces represent a lagoonal sedimentary sequence, cropping out along some quarry walls in the outskirts of the Kisimayo town.

The lower member of the Poleta Formation is well known for its abundant archaeocyaths, including an exceptionally preserved reef at Stewart’s Mill in Nevada. Large archaeocyath-bearing reefs are relatively uncommon, with most occurring as small nearshore patch reefs. Here, we describe a new 70 m-thick archaeocyath reef from the lower Poleta Formation, herein referred to as the Gold Point Reef, located

The sub-fossil red coral of Sciacca (Sicily Channel, Mediterranean Sea): colony size and age estimates Facies (IF 1.8) Pub Date : 2021-02-07 Giorgio Bavestrello, Marzia Bo, Lucio Calcagnile, Martina Canessa, Marisa D’Elia, Gianluca Quarta, Federico Spagnoli, Riccardo Cattaneo-Vietti
The Mediterranean red coral, Corallium rubrum (L.), has been a valuable economic resource for more than 2000 years. The Sicily Channel and surrounding areas are one of the most famous red coral fishing grounds of the whole region, hosting the deepest ever found living colonies and large sub-fossil red coral deposits; the so-called Sciacca banks are a unique location in the whole Mediterranean Sea.
