FIGURE 9 Schematic diagram of profundal to supralittoral zones in underfilled lake-type basins
showing approximate environmental distributions of ichnofacies and idealized vertical distribution
of facies in prograding stratigraphic successions. Dominant controls in underfilled lake-type basins
are high salinities, substrate consolidation, patchy input of freshwater, and relatively low water
tables in basin-marginal settings. Laterally adjacent environments along strike and along deposi-
tional dip both form vertical successions under changing conditions. The idealized sections show
vertical successions along depositional dip. Examples are based on case studies (referenced here)
and predicted assemblages (asterisks). Abbreviations: Me , Mermia ; Sk , Skolithos ; Sc , Scoyenia ;
Ce , Celliforma ; Co , Coprinisphaera ; O-E , Octopodichnus - Entradaichnus ; N, no trace fossils.
The numbers following ichnofacies abbreviations refer to the groupings in Table 2 . References:
