Reconstructing long term sediment flux from the Brooks Range, Alaska, using edge clinoforms
Laterally extensive, well-developed clinoforms have been mapped in Early Cretaceous deposits located in the northeastern 27,000 km2 of the Colville Basin, North Slope of Alaska. Using public domain 2-D seismic data, well logs, core photographs, and grain size data, depositional geometries within …

Reconstructing long term sediment flux from the Brooks Range, Alaska using shelf edge clinoforms
Laterally extensive, well-developed clinoforms have been mapped in Early Cretaceous deposits located in the northeastern 27,000 km2 of the Colvile Basin, North Slope of Alaska. Using public domain 2-D seismic data, well logs, core photographs, and grain size data, depositional geometries within the …

An Integrated Well Log and 3D Seismic Interpretation of Missourian Clinoforms, Osage County, Oklahoma
… context. Shelf-prism and subaqueous, delta-scale clinoforms of Missourian age observed in 3D seismic were interpreted with greater sequence stratigraphic detail when coupled with wireline well logs. The Late Pennsylvanian Midcontinent Sea was thought to be approximately 150 feet average depth …

Stratigraphy, Two-Dimensional Geometry and Internal Sedimentary Structure of Hyaloclastite Deposits in the Siða Formation, SE Iceland; Implications for Mechanisms of Emplacement
… bedding, large-scale (>2m) cross-beds, clinoforms (>5m), “floating clasts” and antidunes in the sheet-like units also infers the occurrence of glacier outburst floods since these features are documented in flood sequences on nearby glacier outwash plains. In contrast, lensoid …

Multi-Disciplinary Analyses of Outcropping Late Cretaceous Clinoform Stratigraphy, Magallanes Basin, Chile
… move from continents to deep-marine basins. Clinoforms, shelf-edge deltas, submarine canyons, and deep-water channels are central components of these systems, yet their stratigraphic architecture, sediment-routing behaviour, fluid trapping potential, and influence on organic matter …

Siesmic Stratigraphy of Upper Pleistocene gravel and holocene mudbelt deposits between wreck point and the kamma river on the western shelf of South Africa
… characterized by a set of prograding sigmoidal clinoforms having formed in response to increasingly limited accommodation space after 5.5 ka. Clinoforms, seismic reflectors with slightly higher amplitude than the underlying units, represent depositional hiatuses during periods of lower …

Sequence stratigraphy and the development of a clinoformal carbonate ramp on an abandoned delta system: Mississippian Fort Payne--Salem Interval, Kentucky
… to 2.5 mIkm (less than 0.25 degrees), although clinoforms of 2 to 10 degrees occur locally associated with mounds and depositional lobes. The supersequence LST is dominated by mounds interlayered with green shaly, deeper ramp facies. The mounded units are located in a fairway that is normal to …

Seismic and Well Log Attribute Analysis of the Jurassic Entrada/Curtis Interval Within the North Hill Creek 3D Seismic Survey, Uinta Basin, Utah, A Case History
… likely indicate an unconformity between Entrada clinoforms below and Curtis planar beds above. This relationship may aid the explorationist in discovering this important seismic interval. Seismic and well log attribute values were cross plotted and have revealed associations between these data. …

Depositional system and source rock potential of the Sharon Springs Formation in Colorado
… correlation connects the progradation of these clinoforms, to prograding sandstones on the western margin of the basin associated with the Blackhawk and Castlegate Sandstone. Similar turbidite deposits and normally-graded siliciclastics have also been described within the Prairie Canyon Member …

CENOZOIC EXTENSION OF THE LAKE TANGANYIKA RIFT, EAST AFRICA: STRUCTURES, TECTONOSTRATIGRAPHY AND PALEOENVIRONMENTAL RECONSTRUCTION
… stands. Spectacular oversized deltaic prograding clinoforms, which may be linked to the outflow of Lake Rukwa, are observed in seismic reflection data within the Lake Tanganyika Rift on the Karema platform. In the absence of borehole data in this area, a numerical modelling approach may be …
