Cored Interval

A Core Interpretation Logic TreeA Core Interpretation Logic TreeSurface of Facies Contrast Recognized

Water has deepened? Water has shallowed?

Above a discrete parasequence/section that shallows up?

Low-accommodation fluvial capped by marine or high-accommodation fluvial?

Substantial deepening and/or evidence of erosion with deepening?

Slight marine-marine shallowing?

Evidence of subaerial emergence or valley fill above marine units separated by erosional scour or paleosol?

Shift from high-accommodation fluvial to low-accommodation fluvial across erosional surface?

Anomalously marine or aqueous section?

Evidence of starvation of terrestrial sediment within marine section?

Evidence of marine flooding interval or interval of raised water table within fluvial section?

Marine Flooding Surface within Condensed Section Marine Flooding Surface within Terrestrial Section

Flooding Surface Maximum Regressive Surface

Transgressive Wave Ravinement

Within Trend Forced Regressive Surface or Basal Surface of Forced Regression (if no erosion) or Regressive Wave Ravinement (if erosional).
