2	Parallel	High	High	High	Sheet	Carbonate platform slope deposits
3	Parallel, subparallel	High	Low to moderate	Moderate to low	Sheet	Aggrading carbonate platform
4	Inclined	Moderate	Low to moderate	Moderate to low	Wedge	Progradational carbonate platform
5	Inclined	High	High to moderate	High to moderate	Wedge	Delta foreset
6	Parallel, subparallel	High to moderate	High	Moderate	Sheet	Shelf deposits
