The Silurian salt serves as a décollement zone above which the younger sedimentary section is involved in a series of folds. The southeastern limb of each of these folds is generally oversteepened. Beds older than the Salina salt are apparently not involved in the folding, as evidenced by seismic data. A comparison of the folds in this area is made with those in other areas underlain by bedded salt. Factors controlling salt-influenced structures include (1) thickness of salt layer, (2) manner of deposition of overburden, and (3) angle of slope of salt-sediment surface during deposition of overburden.
