Abstract/Description
-
The submerged paleodrainage system of the early Balize delta complex that extended onto the inner continental shelf at 1500 YBP has not been completely studied in great detail. This study interprets the environmental deltaic facies of the Balize Delta, in the Sandy Point region offshore the southeastern Louisiana coast from 120 km of seismic data and 48 vibracores. The stratigraphic and environmental units established in this study provide a geological framework for this area. Overlying...
Show moreThe submerged paleodrainage system of the early Balize delta complex that extended onto the inner continental shelf at 1500 YBP has not been completely studied in great detail. This study interprets the environmental deltaic facies of the Balize Delta, in the Sandy Point region offshore the southeastern Louisiana coast from 120 km of seismic data and 48 vibracores. The stratigraphic and environmental units established in this study provide a geological framework for this area. Overlying Holocene deposits interpreted to be muds of prodelta and lower delta front origin were interpreted as having been deposited from the retreating delta sit atop a transgressive surface, indicated by the toplapping seismic reflectors, the ravinement surface. The deltaic facies below the ravinement surface are of regressive origin an inner shelf delta with widespread delta front sheet sands from a dense group of many distributaries. This research provides a concise methodology adapted from multiple studies for modeling deltaic facies of offshore sand resource targets.
