Describe and discuss the sedimentary deposits that you would expect in a deltaic environment. What will be an ideal response?
The student should discuss the origin of river-transported sediments in continental areas.
Deposition of these deltaic deposits is the result of movement of river systems, often with
turbulent flow, into the relatively quiet waters of large lakes or oceans. Sediment types in these
environments include sandstones, shales, and rare carbonate deposits or swamp deposits.
