FIGURE 5 Schematic diagram of profundal to supralittoral zones in overfilled lake-type basins
showing approximate environmental distributions of ichnofacies and idealized vertical distribution
of facies in prograding stratigraphic successions. Dominant controls in overfilled lake-type basins
arewell-oxygenated lakewaters, soft substrates, and highwater tables in subaerially exposed settings.
Laterally adjacent environments along strike and along depositional dip both form vertical succes-
sions under changing conditions. The idealized sections showvertical successions along depositional
dip. Examples of ichnofacies shown are based on case studies (referenced here) and predicted assem-
blages (asterisks). A legend for Figs. 5, 7 and 9 is included here. Abbreviations: Me , Mermia , Sk , Sko-
lithos , Sc , Scoyenia . The numbers following ichnofacies abbreviations refer to the groupings in
