South Atlantic Margins Basic Analysis (Samba): The Brazilian Margin Or Samba, Brazilian Style

The South Atlantic Margins Basin Analysis (SAMBA) study is a multi-phase study to investigate the West African and<br>Brazilian continental margins. It ranges in time across six epochs and in scale from continental to basinal using multiple<br>sets of geophysical and geological data to evaluate the hydrocarbon potential of these conjugate margins. This paper<br>reviews some of the data sets and methods employed and describes results of the regional overview based on special<br>plate-tectonic reconstructions. It concludes with references to the basin scale work offshore Brazil. The results include<br>various criteria important to hydrocarbon exploration such as the continent/ocean boundary, basin limits and controlling<br>lineations. An additional advantage of the project was the placement of interpretation features versus well-defined grid<br>locations and carefully detailed projection parameters. Consequently, new data could readily be added as available.
