Facies architecture and mechanical stratigraphy of Mississippian grainy and muddy carbonate sediment gravity-flow deposits: Rancheria Formation, Sacramento Mountains, New Mexico
Carbonate slope deposits are of considerable scientific importance, economic significance, and academic interest, but remain understudied in terms of depositional processes, facies architecture, fracture distribution, and the resultant mechanical stratigraphy. Outcrops of the Rancheria Formation in …

Sedimentation threats to Red Sea corals : an ecological study of reefs in the Hurghada Region, Egypt
… three decades, associated with an increase in sediment input from coastal development. The aim of this study was to examine the impact of sediment on reef health at a number of sites along the coast of Hurghada encountering differing sedimentation loads. A range of physicochemical parameters …

Palaeoenvironmental reconstruction and geoarchaeology of the Cuatro Cienegas Basin, NE Mexico, from the late Pleistocene to the present
… Jackson [2008]. This project has analysed a 15 m carbonate sediment core for multi-proxy palaeoenvironmental information and combined this with stable isotope, modern hydrological and geoarchaeological information in the Cuatro Cienegas Basin.

Storm-dominated Lower Cambrian depositional environments in the Ravenswood area, Lander County, Nevada
A Lower Cambrian sedimentary sequence 40 meters thick is exposed in the Ravenswood area, Lander County, Nevada. This sequence is divided into 7 lithofacies which are interpreted to represent marine, littoral to sublittoral environments including offshore bars, sheet deposits (proximal, …

Stratigraphy and Depositional Characterization of the Moorefield Shale (Middle-Late Mississippian) in its Type Area, Northeastern Arkansas (Eastern Arkoma Basin)
… region was covered by shallow seas and carbonates covered most of the region. A shallowly dipping carbonate ramp developed in the region providing a foundation for clastic sediment deposition. The Boone Limestone underlies the Moorefield Shale throughout the eastern Arkoma Region …

Controls on Carbonate Factory Distribution in a Restricted Intraplatform Basin: Upper Jurassic Smackover, Southwest Alabama
… Basin, southwest Alabama, and examines the carbonate factories responsible for sediment production. Four wells with associated cores and log data were analyzed, alongside geochemical proxy concentrations measured via X-ray Fluorescence (XRF) and Laser Induced Breakdown Spectroscopy (LIBS). …

Porosity Development Within Lobes to Downslope Ramp Deposits on a Prograding Carbonate Shelf of the Kinderhookian to Osagean Series in Northwest Arkansas
<p>Carbonate bodies with lobate geometries form a substantial part of the Osagean (early Mississippian) section in northwest Arkansas. The purpose of this study is to isolate and describe a single lobe from three-dimensional exposures in quarry walls to provide criteria by which lobe and lobe …

High resolution sedimentary archives of past millennium hurricane activity in the Bahama Archipelago
… archives of storm activity derived from sediment cores from blue holes on three islands in the Bahama Archipelago: South Andros, Long Island, and Middle Caicos. Dramatic differences between these records suggest localized controls on the hurricane patterns observed by each island. Thus, …

Sequence Stratigraphy and Petrophysics of the late Ordovician Utica-Point Pleasant Interval in the Middle Appalachian Basin, Eastern Ohio and Western Pennsylvania
… margin of North America. The transition from a carbonate-dominated system to a clastic-dominated system reflects the drowning of a widespread carbonate platform. The units of the Trenton Group and Lexington Limestone through Utica Shale comprise the transgressive systems tract (TST) of a large …

Paleogeography and Paleoenvironments of the Lower Unit, Fossil Butte Member, Eocene Green River Formation, Southwestern Wyoming
<p>During Eocene time sediment accumulated in Fossil Lake, in what developed to be a small linear and structurally controlled basin. Fossil Lake was one of several lakes into which the Green River Formation was deposited in Wyoming, Utah and Colorado.</p> <p>Detailed stratigraphic analysis of the …

Geology and mineral resources of the Goose Creek area near Roanoke, Virginia
… part of the area is underlain by soft shales and carbonate rocks and has encroached on the edge of the Blue Ridge thrust plate. Southwestward-flowing Glade Creek and its main drainage area is similar to the Great Valley in physiography and type of bedrock. It extends northeast into a breached area …

INTEGRATING SEDIMENTOLOGY, STRATIGRAPHY, GEOCHEMISTRY AND 3D GEOLOGICAL MODELLING: CONTRIBUTION TO GEOLOGICAL MAPPING FOR LAND KNOWLEDGE (CARG SHEET 081 ¿ROVERETO¿)
… PhD thesis focuses on the Rhaetian(?)-Tithonian carbonate succession of the Trento Platform, one of the Jurassic structural highs of the Western Tethys Ocean, cropping out in the Folgaria plateau and in the Pasubio Massif areas (Trentino-Alto Adige region, N Italy). The Trento Platform carbonate …
