sediments is also important because it modifies the movement <strong>of</strong> salt and the movement<br />
<strong>of</strong> salt will alter sediment deposition.<br />
One <strong>of</strong> the more challenging aspects to describing the geology <strong>of</strong> Vinton Dome is<br />
properly identifying the cross-cutting relationships between regional-scale structures and<br />
salt bodies. Unraveling the relative timing <strong>of</strong> the structures is necessary to understanding<br />
the relationship between faulting and emplacement <strong>of</strong> salt bodies.<br />
The Neogene was a period <strong>of</strong> significant salt tectonics, growth fault development, and<br />
maximum clastic deposition along the outer shelf and upper slope that occurred in the<br />
northern Gulf <strong>of</strong> Mexico Basin (Lowerie, 1994). All <strong>of</strong> these processes took place<br />
synchronously (Lowerie, 1994), possibly linking them.<br />
2.2 Basin Formation<br />
Bounding the Gulf <strong>of</strong> Mexico Basin to the east is the Florida Carbonate Platform, to the<br />
south by the Yucatan Carbonate Platform (Figure 2) (Ewing, 1991), to the west by the<br />
Chiapas massif, the Sierra Madra Oriental, and the eastern edge <strong>of</strong> the Coahuila Platform<br />
in Mexico. Northern limits are defined, from west to east, by the structural limits <strong>of</strong> the<br />
Marathon uplift, the Ouachita orogenic belt, the Ouachita Mountains as delineated by the<br />
Mexia/Talco fault, the Central Mississippi deformed belt, and the southern extent <strong>of</strong> the<br />
Appalachian Mountains. There is no distinct structural limit to define the boundary<br />
between the southern Appalachians to the Atlantic Ocean.<br />
