The bounding discontinuities used to delineate the Sparky Allomember correspond to marine flooding surfaces (FS). Based on the integration of ichnological and sedimentological characteristics of succession, ten discrete facies have been identified. These are combined into five recurring facies associations.Facies Association 1 (FA1) comprises sediments deposited below fairweather wave base but above storm wave base. Facies associations 2 and 3 (FA2 and FA3) coarsen upward and represent the progradation of wave- and storm-dominated shorefaces as well as mixed river- and wave-influenced deltas, respectively. Facies Association 4 (FA4) typically cuts through FA3, and displays a fining-upward trend, and is interpreted as distributary channel deposits. Complete cycles of FA2 and FA3, wherein the tops of the cycles have not been removed by downcutting channels, are capped by coastal plain/delta plain deposits of Facies Association 5 (FA5). The Sparky Alloformation terminates at an upper contact marked by renewed marine transgression and the formation of a regionally extensive transgressive surface of erosion (TSE).Three coarsening-upward cycles are identified within the Sparky Alloformation, each bounded by allogenically produced flooding surfaces. These units, termed Lower, Middle and Upper allomembers, are characterized by wave-and storm-dominated shorefaces and associated mixed river-and wave-influenced deltaic successions reflecting progradation towards the N-NW. The Sparky Alloformation consists of sediments deposited during periods of pronounced progradation and corresponds to a highstand systems tract. You do not currently have access to this article.

Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Apprise à partir de 10 348 étiquettes directes de Codex et de 10 348 étiquettes directes de Gemma. Le mode candidate est l'union des têtes enseignantes seuillées; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont ni des étiquettes humaines ni des étiquettes directes de modèles de pointe.
