[[File:YGS_CHR_04_DINA_FIG_12.jpg|thumbnail|Figure 12 A correlation panel for wells that penetrate typical cyclic Millstone Grit Namurian successions. The succession is dominated by upwards-coarsening units and channel sandstones. The bases of cyclothems are commonly marked by a high-gamma mudstone that is likely to be a marine band. The major marine bands are labelled. The identification of those below top Kinderscoutian is tentative.]]

Ages are only loosely constrained. All wells have gamma and sonic logs with an interpreted lithology.]]
