Regional dip generally to W
folds and interruptions to matrix
This trend are result of penetrative synclinal folding due to compression of thick coal seams under the sand channels
Folding thus due to loading under massive channel axes
Areas of thick coals & channel focusing characteristic of a deltaic situation. Lack of marine fossils would seem to indicate upper delta.
