Depositional Model of a Late Cretaceous Dinosaur Fossil Concentration, Lance Formation
… of deposition. This study aims to provide a depositional model for the bonebed. To accomplish this task we utilized 1D facies analysis of surrounding units and 3D analysis of the bonebed. The nature of the outcrop limited facies analysis to 1D. Four measured stratigraphic sections, each …

Stratigraphy And Depositional Environments Of Lower And Middle Cambrian Strata In The Lake Mead Region, Southern Nevada And Northwestern Arizona
The stratigraphy and depositional systems revealed within the Lower to Middle Cambrian Tapeats Sandstone-Pioche Shale-Lyndon Limestone-Chisholm Shale succession were studied between the easternmost limit of Cretaceous overthrusting in southern Nevada and the western edge of the Colorado Plateau in …

Petrographic, geochemical, and textural analyses of interbedded gypsum and Cu-ore deposits in the Upper Miocene Boleo Formation, Baja California Sur, México
… findings reflect a synsedimentary-syndiagenetic depositional model influenced by fluid–rock interaction, brine evolution, and diagenetic processes.

Subsurface Sequence Stratigraphy and Reservoir Characterization of the Mississippian Limestone (Kinderhookian to Meramecian), South Central Kansas and North Central Oklahoma
… the sequence stratigraphic interpretations, depositional models, and formation names applied to the reservoir intervals within the subsurface. Another major issue with regard to the subsurface is the stratigraphic position and origin of tripolitic chert development. Previous outcrop studies …

Genesis and Sedimentation of an Ice-Walled Lake Plain in Northeastern Illinois
… the sedimentology of the IWLP and iii) propose a depositional model for development of the IWLP. The study was conducted on a single IWLP in Newark, Illinois, located in the Marseilles Morainic System. Seventeen radiocarbon ages of tundra plant macrofossils were obtained from cores sampled across …

A study of anisotropy of magnetic susceptibility’s effectiveness in understanding palaeoflow systematics in shale basins
… palaeoflow and geographically confined depositional model that spans a very short period. This project explored the viability of using Baas et al., (2007) description of the petrofabric’s AMS as a means to establish delivery mechanism. The Ainsa System showed two modes of AMS, one that …

Depositional History and Petroleum Potential of the Middle Devonian Fort Vermilion Formation, Alberta
… subaerially in a sabkha environment, a new depositional model is proposed for this unit whereby sedimentation occurred subaqueous in a protected, variably deep, restricted basin. Based upon core examination, petrography, and various geochemical analyses, four facies assemblages representing …

Micropalaeontology, Palaeoenvironments and Sequence Stratigraphy of the Sulaiy Formation of Eastern Saudi Arabia
… evidence of the sedimentary palaeoenvironmental model namely the Arabian Rimmed Carbonate Platform. This palaeoenvironmental depositional model is characterised by two different platform regimes. They are the Platform Interior and the Platform Exterior each of which have unique sedimentary …

New stratigraphy, polyphase deformational history and basement-involved thrust belt model for the Proterozoic Uncompahgre Group and Vallecito Conglomerate, Needle Mountains, Colorado
… southwestern Colorado, provide insight into the depositional and deformational history of one of the best exposed of these Paleoproterozoic cover successions. This study documents a gradational contact between the basal Vallecito Conglomerate and the overlying Uncompahgre Group and offers a …

Provenance, geochronology and sedimentary characteristics of the Campanian M1 Sandstone, Napo Formation, Oriente Basin, Ecuador
… reservoir behavior suggests that the depositional environments of the M1 Sandstone were laterally variable, such that they generated complex reservoir compartmentalization. This complexity also makes it difficult to determine whether multiple sandstone units of 5-20 m thickness …

Facies, stratigraphy, and mineralogy of the carbonate marker and D marker units, lower Green River Formation, Uinta Basin, Utah
… were identified that correlated to unique depositional environments within the lake. These include delta, mudflat, shoal complex, and sublittoral deposits. Facies associations were incorporated into a lacustrine depositional model to track transgressive and regressive periods in the lake. …

The Broom Creek Formation (Permian), in southwestern North Dakota: depositional environments and nitrogen occurrence
… the Broom Creek Formation. </p><p> A four-phase depositional model is proposed for the preservation of eolian dunes within the Broom Creek Formation, 1) migration of eolian dunes over a low-relief erosional surface, 2) marine transgression and partial reworking of dunes, 3) carbonate mud …

The sedimentology of the Bloomington fan complex: an element of the Oak Ridges Moraine, Southern Ontario
… deposited the Halton Till. The subaqueous fan depositional model that is postulated for the Bloomington fan complex differs from published models due to the complex facies associations produced by the multiple conduit sources of sediment feeding the fans. The fluctuating northern and southern …

Sequence Stratigraphy and Petrophysics of the late Ordovician Utica-Point Pleasant Interval in the Middle Appalachian Basin, Eastern Ohio and Western Pennsylvania
… northern West Virginia are used to construct a depositional model of the Utica Shale and associated Upper Ordovician strata. Previous studies of outcrop data from the Cincinnati arch and Jessamine dome recognized a number of Late Mohawkian to Early Cincinnatian third-order sequences deposited in …

Depositional environments and sandstone diagenesis in the Tyler Formation (Pennsylvanian), southwestern North Dakota
… units, reflecting both a change in lithology and depositional environments. The lower unit is dominated by varicolored, noncalcareous shales and mudstones, siltstones, thin coal beds, and medium-grained sandstones. The upper unit in the areas of the Square Butte to Fryburg fields may be divided …

Stratigraphy, depositional environments, and petroleum potential of the Three Forks Formation -- Williston Basin, North Dakota
… types that result from diagenetic and depositional events. Six members of the Three Forks are identified and log-derived porosities, water saturations, and net-togross values for each Member calculated and areas with high reservoir quality and potential pay zones highlighted. Also, core …

The stratigraphy and sedimentology of the Bredasdorp group, southern Cape Province
… Bredasdorp Group. In order to construct a depositional model for the Bredasdorp Group, various facies have been identified on the basis of geometry, lithology, fossil contents, palaeocurrent data, biogenic and sedimentary structures. The facies are related to environments constituting a …
