The Mississippi fan foldbelt is a series of east-trending anticlines associated with primarily north-dipping thrust faults in the northern Gulf of Mexico. The foldbelt is approximately 300 km in length and a minimum of 50 km in width. The folds contain strata of Middle Jurassic through Pliocene( ) age, based upon correlations with deep Gulf of Mexico seismic units (Challenger, Campeche, lower and upper Mexican Ridges, and Cinco de Mayo). The series of thrust faults and anticlines becomes younger basinward to the south and formed localized, confined turbidite basins in the adjacent synclines to the north. This foldbelt represents the compressive toe of a complete growth fault system where updip sediment loading caused downdip compression and decollement formation. The folds reflect where the decollement ramps up.
