Sequence Stratigraphy, Depositional Environments, and Regional Mapping of the Late Devonian Interval, Upper Three Forks Formation, Sanish Member, and Lower Bakken Shale, U.S. Portion of the Williston Basin
… of several significant sequence stratigraphic surfaces.;The four facies identified in the Sanish include: Facies A, a dolomitic and Skolithos burrowed sandstone with a hard-ground at the base as originally defined in the Antelope Field; the widely distributed Facies B, a dolomitic siltstone …

Lithological and sequence stratigraphic examination of the Madison Group marker beds, eastern Williston Basin margin, North Dakota
… the basal contact represents a fourth-order maximum flooding surface. Dolomitic sandstone markers reflect initial deposition during a lowstand systems tract with unconsolidated sediments reworked and further cemented with the subsequent transgressive tract. Contrasting sediment input and …

Stratigraphy and Palaeontology of the Late Cretaceous Wapiti Formation, west-central Alberta, Canada
… 3) the identification of previously undetermined maximum flooding surface of the Bearpaw seaway and Drumheller Marine Tongue, which are reference marine unit in central and southern Alberta. A second, but not less important, guideline for the project has been the rich paleontological record of the …

Source rock potential of the Bakken shales in the Williston Basin, North Dakota and Montana
… of the depositional setting. The location of maximum flooding surface was identified near the top contact of the lower and upper Bakken shales, where the most enrichment of V and Ni occurs. Oil-generation kinetics were also experimentally derived by the method of hydrous pyrolysis from the …

Reinterpreting vintage geophysical data from the Algoa and Gamtoos Basins, South Africa: an integrated sequence stratigraphic framework since the middle Mesozoic
… schools of thought to define stratigraphic surfaces. This has resulted in multiple sequence stratigraphic models that interpret the same data differently. The limited exploration, to-date, and poor dataset quality have impeded the understanding of the geological evolution of the offshore …

Regional stratigraphic framework of the Tuscarora Sandstone: A model for geologic CO2 storage in West Virginia
… into a transgressive systems tract (TST), with a maximum flooding surface (MFS) occurring within the middle member. Above this MFS is the regressive systems tract (RST) which includes the lower portion of the upper member. Within the upper member, a transgression occurs with a second sequence that …

Outcrop-derived facies model and cycle architecture of the Tansill G27-G28 high-frequency sequences, Rattlesnake Canyon, New Mexico
… of the G27-G28 HFSs further constrains the maximum flooding surface (MFS) of the CS13 and indicates a rocky shoreline juxtaposed against the windward side of shelf-crest tepee-pisolite barrier-island complexes. Previous studies have emphasized the stacking patterns comprising the outer few …

Microfaunal investigation of the Early Toarcian (Lower Jurassic) extinction event in N.W. Europe
… and correspond to published estimates of a maximum flooding surface. Interpretations of the benthic foraminiferal assemblages surrounding this event provide further support for a transgressive event -associated with the development of low oxygen conditions and the deposition of organic-rich …

Benthic foraminiferal change and depositional history across the Cretaceous – Paleogene (K/Pg) boundary in the Brazos River area, Texas
… is shown to infill troughs on this irregular surface. The same features were recorded in tributary creeks, with all previous descriptions of these locations clearly failing to recognise the various sedimentary relationships. Distinct, thin, yellow clay horizons within the uppermost …

Micropalaeontology, Palaeoenvironments and Sequence Stratigraphy of the Sulaiy Formation of Eastern Saudi Arabia
… sedimentology of the Sulaiy Formation in the subsurface have indicated a succession of clearly defined shallowing−upwards depositional cycles. These typically commence with a deep marine biofacies with wackestones and packstones, capped with a mudstone-wackestone maximum flooding zone and an …

Estratigrafia de sequências do intervalo aptiano ao albiano na Bacia do Araripe, NE do Brasil
… For the selection of the datum the deepest maximum flooding surface was chosen, inside the Sequence 1, the execution of these sections allowed to understand the behaviour of six depositional systems along the study area, which were interpreted as cycles of second order or supercycles (cycles …
