QUANTIFYING MIXED-PROCESS VARIABILITY IN SHALLOW-MARINE DEPOSITIONAL SYSTEMS: WHAT ARE SEDIMENTARY STRUCTURES REALLY TELLING US?

摘要

Interpreting the whole range of fluvial, wave, and tidal interactions recorded in shallow-marine, coastal successions can be challenging. The complexity arises because sedimentary structures produced by all three processes can be fully or partially preserved in the same stratal packages, and many of these structures are not diagnostic of a specific process. We therefore need an improved method of capturing the internal facies complexity that characterizes mixed-process coastal systems.
