Lower and upper boundaries
Base not seen, but presumed transitional on the Millport Cornstones Member (Figure 6, Column 2).
Top not seen, but presumed overlain by extrusive igneous rocks of the Clyde Plateau Volcanic Formation.
About 150 m. However, BGS (2008) gave a generalised thickness of 128 m for the formation.
