ABSTRACT

A synthesis of seismic, borehole, and gravity data in southeastern Rusk County, Texas indicates that faulting within the Mt. Enterprise fault system was the result of Jurassic age salt tectonism. Faults were developed in response to salt movement and subsequent collapse of the overlying section into areas of salt withdrawal, resulting in the formation of a graben containing no Louann Salt. An abnormally thick Bossier Formation within the graben defines a Late Jurassic age for significant structural deformation within the fault zone.
