The Sigsbee Escarpment is a major bathymetric feature of the Gulf of Mexico, extending for about {{convert|560|km|mi|abbr=off}}. It separates the lower continental slope of the northern gulf from the abyssal plain of the Sigsbee Deep and has up to {{convert|900|m|ft|abbr=on}} of relief across it.[1] It has formed as a result of salt tectonics, due to the effects of loading of a thick layer of Jurassic halite (Louann Salt) by Upper Jurassic to Cenozoic sedimentary rocks.[2] References1. ^{{cite book |url=http://pgc.lyellcollection.org/content/7/899.abstract| chapter=Some emerging concepts in salt tectonics in the deepwater Gulf of Mexico: intrusive plumes, canopy-margin thrusts, minibasin triggers and allochthonous fragments | title=Petroleum Geology: From Mature Basins to New Frontiers—Proceedings of the 7th Petroleum Geology Conference | publisher=Geological Society |editors=Vining B.A. & Pickering S.C.| author=Jackson M.P.A., Hudec, M.R. & Dooley T.P. | year=2010 | location=London | pages=899–912 |series=Petroleum Geology Conference|volume=7| isbn=9781862392984}} 2. ^{{cite web | url=http://www.gcssepm.org/conference/2004_Prog_Abs.pdf | title=A New Mechanism for Advance of Allochthonous Salt Sheets | work=Salt-Sediment Interactions and Hydrocarbon Prospectivity: Concepts, Applications, and Case Studies for the 21st Century | accessdate=16 November 2014 |author1=Jackson M.P.A. |author2=Hudec M.R. |lastauthoramp=yes | pages=11|year=2004}} 1 : Gulf of Mexico |
