Figure 3--Hypothetical cross sections illustrating regional setting of Plattsburg bank during deposition. Horizontal dimensions are purposely omitted because of insufficient knowledge. Deposits equivalent to Plattsburg south of bank consist partly of shale, as limestone layers pinch out. Presence of land area to south is conjectural, but is suggested by general increase in proportion of shale in upper Pennsylvanian rocks toward south. A. Bank during deposition of middle part of Spring Hill member, showing contemporaneous deposition of Vilas Shale. B. End of deposition of bank followed by complete encroachment by Vilas Shale.
