Gulf of Mexico-Campeche Knolls - United States of America

Gulf of Mexico

United States of America

The Campeche Knolls are diapirs rising from a salt deposit in the southern Gulf of Mexico, separated from the Mississippi-Texas-Louisiana salt province by the Sigsbee Abyssal Plain. Located southeast of the Sigsbee Knolls, the Campeche Knolls are bounded by Campeche Bank to the East, the Bay of Campeche to the South, and the salt-free abyssal plain called the Veracruz Tongue to the West. Salt deposition is inferred to have occurred in the Late Jurassic, during the rifting stage of the gulf, equivalent to the Louann Salt of the Texas-Louisiana slope. Multibeam echosounder images collected during R/V Sonne cruise SO174 show the northern Campeche Knolls as distinct, elongated hills that average 3 by 6 mi (5 by 10 km) in size, with reliefs of 1,475 to 2,625 ft (450 to 800 m) and slopes of 10 to 20 percent.

The Campeche Knolls are covered with a thick column of sediments above the salt unit, with sediment thickness reaching 3-6 mi (5–10 km) depending upon water depth and distance from the southern coast. The thick sediments provided prolific petroleum source rocks with... read more on Wikipedia
