Austin Exploration acquired and compiled a detailed gravity survey along the Ouachita Trend in Mississippi.

There is a strong density contrast between the clastic section above the Devonian and the carbonate section below. This allows precise delineation of the structure in the lower Paleozoic by the gravity method.

The regional structure can be seen from the gravity, including the union of the Ouachita Trough and the Appalachian Basin, at right angles, south of the Black Warrior Basin.

Local anticlines, faults and synclines are also mapped in detail by the gravity.

 

Specifications:

The data were recorded using high standards of accuracy.

The maximum elevation difference at tie points was less than one foot and this was prorated down the traverses.

The gravity data are accurate to less than 0.05 milligals.

The plat shows the number of stations by 30 minute quadrangles.

Bouguer Gravity Maps are provided.

Residual Gravity Maps that are appropriate for the area data are available for the quadrangles.
