Clinoforms
WebMay 16, 2024 · Since high sediment supply often results in steeper clinoforms [59,78], we expected that shorefaces in zones I and II would be steeper than eastern shorefaces. One explanation for the disparity between our observations and stratigraphic principles is that upper shoreface morphology in eastern Rockaway reflects human interventions at the ... WebA clinoform is a two-dimensional surface with a sigmoidal (sloped) geometry that is characteristic of basin margin strata. They are timelines that represent a moment in geological time. clinoforms can be recognized in …

WebClinoforms and clinothems represent a dominant architectural style of strata in many sedimentary environments, including deltaic and nondeltaic shorelines in both marine … WebClinoforms occur at a wide range of spatial scales, from large, basinward-dipping surfaces at the shelf-slope margin, to smaller surfaces associated with progradation of deltaic and shoreface systems across the shelf (e.g., Helland-Hansen and Hampson, 2009). This study focuses on developing a surface-based approach to represent clinoforms at ...

Collect … WebJan 9, 2024 · A suite of sediment types, including mass-transport deposits (MTDs), deltaic clinoforms, contourite-drifts and turbidites, are documented based on high-quality 3-D seismic reflection data and multiple regional 2-D seismic profiles.
WebShallowing-upward prograding clinoforms are a second characteristic system of the Mozduran Fm., whereby ooids, generated under shallow-water conditions, were shed downslope to form interbeds within basinal mudstones. Our findings suggest that the combination of 2nd order eustatic sea-level changes with hydrodynamic processes as … WebJul 29, 2024 · The lacustrine Itapema Formation in the Santos Basin locally comprises 10 2 m thick clinoforms identified seismically and corroborated by several well penetrations. Individual clinoforms, as proven by well penetrations, are composed of 10 2 m thick successions of basinward-dipping molluscan grainstones and rudstones.
WebFeb 23, 2024 · These oblique clinoforms can be interpreted as forming when sediment supply exceeds the accommodation space and causes shelf-margin progradation; sea …

The sigmoidal … mp4 iso変換 フリーソフト ロゴ無しWebAll clinoforms are consistently oriented sub-parallel to the edge of the Horda Platform (N005–N030). In the eastern half of the field, individual foresets are relatively gently dipping (1° to 6°) and bound thin (10 to 30 m) clinothems. Core data indicate that these proximal clinothems are dominated by fine-grained, hummocky cross-stratified ... mp4 itunes 追加できないWebTowards the west, clinoforms gradually become steeper (5° to 14°) and bound thicker (15 to 60 m) clinothems that comprise medium-grained, cross-bedded sandstones. Topsets are consistently well-developed, except in the westernmost area. No seismic or sedimentological evidence of subaerial exposure is observed. mp4 m4a 変換 オンライン
