Low-accommodation detrital apron alongside a basement uplift, Pennsylvanian of Midcontinent North America

The BPC are lithologically comparable to contemporaneous deposits alongside the Ancestral Rockies, Amarillo-Wichita Uplift, and other buried basement highs in North America. Nonetheless, the BPC are an order of magnitude thinner, are dominantly retrogradational, rather than progradational, and their occurrence was not associated with major displacements along basin-bounding faults. In this manner, the BPC are a useful example of low-accommodation, eustasy-dominated, coarse-grained terrigenous clastic deposition around an uplifted basement block.
