Pottsville Formation, Black Warrior Basin (08)

Alabama and Mississippi

Comments on Geologic Parameters

08 Continuity of Top Seal:

A northwest-trending, high-angle normal fault, which probably formed in response to the compressional forces associated with the Ouachita Orogenic Belt, is the main structural feature of the basin. Two major lineaments are also present. One trend, N30-60E, is parallel to the main trend of normal faults (Pashin and others, 1991). The faulting influenced sediment deposition and induced natural fractures that often enhance permeability and affect diagenesis.
