... ( Figure 9A–C ). On seismic profiles, these features are defined by a moderate- to high-amplitude seismic reflection trough from the top and by a moderate-amplitude seismic reflection peak from the base. They extend approximately 200 ms (about 400 m [1312 ft]) upward in the stratigraphy and commonly pierce...

... in the complexity of our stratigraphic interpretations and analysis methods needs to be addressed, perhaps by more integration of outcrop and experimental modeling analysis. A basic premise of much stratigraphic analysis is that an external signal (e.g., climatic oscillations) is often present in strata...
