Abstract

Clear reflections at times of approximately 2.3 and 4.4 seconds were obtained consistently on a series of records shot directly over the shallow cap rock of the Moss Bluff dome. The earlier reflection can be interpreted as from the base of the salt column, at a depth of around 16,000 feet, or from a discontinuity within the salt column. The later reflection can be interpreted as from the base of the salt column at around 36,000 feet, from the basement complex at around 26,000 feet, or as a multiple of the reflection from the base of the salt column at around 16,000 feet. Reasons are given for preferring the multiple reflection interpretation.
