Open publisher page 2 citations

Abstract

This work discusses the tectonic evolution of the Tucano and Sergipe rift basins onshore and offshore the northeastern Brazilian region, based on integration of deep seismic reflection profiling, potential methods, geological data, and tectonic analysis. We address the following themes: a) the geologic evolution of the rifts; b) the potential methods response to the deep structure of the rifts; c) the seismic expression of major tectonic features; and e) a possible geodynamic model for the evolution of the rift system.
