Stratigraphy

This section describes, in ascending order, the rock units that enclose the Springfield Coal and Galatia paleochannel(Figure 4). To facilitate discussion of the new depositional model, two new members are proposed.

Figure 4 Diagram showing units between the Houchin Creek and Herrin Coals, including members newly named in this report.
