A Core Interpretation Logic Tree
Surface 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? Within Trend Forced Regressive Surface or Basal Surface of Forced Regression (if no erosion) or Regressive Wave Ravinement (if erosional). Flooding Surface Maximum Regressive Surface Transgressive Wave Ravinement Subaerial Unconformity 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
