Six third order depositional sequences were deposited during a second order transgressive-regressive cycle. Parasequences are subtidally dominated and capped initially by relatively thin but laterally extensive bulbous stromatoporoid framestones and later by thick tabular to massive stromatoporoid framestones. Subaerial exposure is recorded only at the top of such sequences. They are initially capped by relatively thick but laterally restricted tabular-massive stromatoporoid framestones but become more peritidal dominated upwards and record repeated periods of subaerial exposure. Sequence geometries vary systematically within the second order transgressive-regressive cycle.
Progradational geometries occur during early second order transgression and late regression.
Aggradational geometries are found during late second order transgression and early regression. The second order transgressive phase effectively sequestered siliciclastic sediments to the eastern portion of the basin. High rates of carbonate productivity fostered the development of a prograding platform across the underlying homoclinal ramp during early second order transgression followed by an aggrading, bypass platform margin during late transgression and early regression. Basin filling due to increased siliciclastic input during the second order regressive phase reduced the paleotopography permitting late regressive platform progradation. Thus, platform margin geometries are affected by second order relative sea-level but are also influenced by the interplay between carbonate productivity and clastic sediment supply.
