PRESENT STRUCTURE
TOP OF SMACKOVER FORMATION

Figure 8.2 Present structure of North Haynesville Field showing the E – W elongate, faulted,

salt - generated anticline that formed contemporaneously with Jurassic Smackover deposition.
Note that structurally high positions are those nearest the fault zone. Crests of salt - related
highs are typically the sites of grainstone accumulations, many of which are oil and gas res-
ervoirs. Adjacent, off - structure rocks are nonreservoir mudstones and wackestones. (Adapted
from Bishop ( 1968 ).)

ridges are elongate and relatively thin; salt pillows are somewhat like thick, short
ridges, and salt domes can be very thick, cylindrical salt bodies. Salt begins to deform
with comparatively little overburden, because some low - relief structures were rec-
ognized to have formed during or before Smackover deposition (Hughes, 1968 ).
