Importance of the Correct Map

Importance of the Correct Map


Regional gravity maps are often used to interpret regional trends and structures of the subsurface geology. This West Florida Shelf example compares free-air, Bouguer, and isostatic residual maps—all developed from the same basic data—with published regional geology of the West Florida Shelf. The comparison illustrates how only one map, the isostatic residual, can be readily interpreted to agree with the identified geologic features. In final analysis, the most important consideration should be use of the gravity data which provide the soundest geologic interpretation.
