Abstract
Summary
Low resolution regional magnetic and satellite gravity datasets were used to conduct an interpretation of the crustal structure along the Equatorial Margin of Brazil. Unique potential field interpretation techniques were used to map basement with a resolution of 10×10km and Moho with a resolution of approx. 30×30km. The crustal structure, including major faults, troughs and crustal highs were mapped along the 2000km long Equatorial Margin. The depth to basement derived from the potential field data shows good correspondence to the available well and seismic data.
