For the lower part of the washover sequence, a mixing of deposits from different depositional environments is documented.
The Upper Tertiary rocks were deposited in the peripheral basins of the Peninsula followed by the Quaternary deposits of varied depositional environments.
Certain related deposits exhibit contrasting mineralogies evidently owing to somewhat different depositional environments.
These landslide deposits provide an opportunity to observe pedogenic processes across differing moisture conditions and depositional environments in ultramafic terrain.
The depositional environments involved include beaches, lagoons, river channels, and backwater swamps.
A number of ways of classifying depositional environments exist, but most modern schemes employ a geomorphologic approach.
Above these wedges we see a variety of sedimentary geometries related to pelagic sedimentation and other, more complex depositional environments.
These rocks are usually reddish, generally immature, very poorly sorted, and frequently interbedded with arkose conglomerate; alluvial fans or fluvial aprons are the main depositional environments.
Anaerobic depositional environments with internal carbon dioxide pressures of about 10−2.5 atmosphere prevailed, and the oxygen-deficient atmosphere itself may have had a carbon dioxide pressure close to 10−2.5 atmosphere.
The atmosphere at the time was oxygen-deficient; anaerobic depositional environments with internal carbon dioxide pressures of about 10−2.5 atmosphere were prevalent, and the atmosphere itself may have had a carbon dioxide pressure near 10−2.5 atmosphere.
Different depositional environments caused serious heterogeneity in this oilfield.
