==Depositional cycle==

The data from the High Island–East Breaks shelf-margin delta suggest that regionally extensive and uniform layers of mud occur above and below locally shingled clinoform packages. Couplets of these two depositional facies constitute a sequence of one depositional cycle. The position of the sequence at the shelf edge suggests that it is composed of a shelf margin systems tract and a condensed section.
