According to general usage among geologists, the Pennington Formation corresponds to shales, sandstones, and thin limestone beds located above the highest massive limestone bed of the Newman Formation.[2]Paleosols have also been preserved in a Pennington outcrop at Pound Gap, recording a series of fluctuations in climate between dry and wet conditions.[3] The Pennington Formation has been inferred to represent a coastal environment transitioning between a Mississippian marine basin and Pennsylvanian coal swamps.[4]
