Análise preliminar dos dados magnéticos do Saco de Mamanguá e da Enseada de Paraty-Mirim, Rio de Janeiro

In the present work we investigate the magnetic anomalies located in the adjacent coves of the Paraty-Mirim and the Saco de Mamanguá, Rio de Janeiro, through marine magnetic and aeromagnetic data. In this preliminary study we filtered the data using upward continuation of 1500 meters and power spectrum analysis to characterize these anomalous. In addition, we obtain 3D magnetic models through the Geosoft VOXI Earth Modeling Cloud Inversion solution using the Magnetization Vector Inversion (MVI) technique. Through the interpretation of inversions we noticed anomalies with patterns of lineaments that extend beyond the study area. The presence of zones with distinct magnetic characteristics in a region of low magnetic latitude showed to be significant and encouraged hypotheses about the origin of these bodies
