Title: Salt-Dome Configuration: ABSTRACT

Author(s): Marcus A. Hanna

Article Type: Meeting abstract


Factors which cause modification of a symmetrical plug to the configuration of the various salt stocks found in the Gulf Coastal area are evaluated. This configuration includes the limestone, gypsum, and anhydrite cap rock, as well as the spines, overhangs, and leaning plugs. Considered also are certain salt-stock rim-synclinal effects, as well as some resulting structural changes in the surrounding sediments.

The character of the salt as a metamorphic rock, the orientated fabric of certain of the anhydrites, and the modifications caused by density differences in the salt and surrounding sediments, and the effect of circulating waters are cited. Several of the theories of salt-plug origin and growth are considered in light of present information.
