Reconhecimento Aeromagnético E Gravimétrico Do Arcabouço Estrutural Da Bacia Rio Do Peixe - Pb

An aeromagnetic and gravity investigation was<br>conducted in the Rio do Peixe basin, NE Brazil. Several<br>geological and geophysical evidence indicate a strong<br>structural control of pre-existing upper crustal weakness<br>zones in the development of the graben architecture of<br>this basin. The digital processing of the aeromagnetic<br>data supplied an analytic signal map of the area, which<br>together with a three-dimensional gravity modeling<br>revealed the magnetic signature of two major structural<br>domains and an estimate of the internal geometry of<br>the rift basin, respectively.
