In this case, the magnetic characterization has an important role that the interpreter has as a tool to understanding the regional structural geometry of this basin, not only to add seismic interpretation, but also because the comprehension at geodynamic-scale: effectively map outlines of magnetic sources are used to characterize the internal structure of the domains and to aid in their delineation. In this paper, we used SPI and AS methods show the edge locations, depths, and dips. The basement domain map was deriving from geometric attributes like total horizontal gradients and Gaussian curvature. Analysis of previously interpretations and published maps were used to formulate the concept of magnetic domains in a geodynamic framework.
