This paper presents eighteen geophysical maps covering nine salt domes and deep-seated structures of the Texas and Louisiana Gulf Coast. Two shallow domes, namely, Moss Bluff and Fannett, are given. Fannett is a gravity maximum, and Moss Bluff is a combination of a gravity minimum and maximum. The Sugarland dome is given as an example of a medium-depth structure, which is indicated by the torsion balance as a minimum. Six deep-seated structures are shown, including Sheppards Mott, Pledger, Mykawa, Tombali, Livingston, and English Bayou-Gillis. The deeper-seated structures invariably show a gravity-minimum influence.
A refraction seismograph map of Moss Bluff is given, and reflection-seismograph maps are given for Sheppards Mott, Tombali, and English Bayou-Gillis. A magnetic map of the Fannett field is likewise presented.
