Abstract

This work identifies and quantifies the geometry and kinematics of faults affecting the Barreiras Formation in the eastern part of the Potiguar basin, Brazil. Focus is on the tectonic evolution of the study area and the quantification of fault offsets. Sedimentary rocks along the eastern coast of the State of Rio Grande do Norte are affected by faults that trend mainly NE-SW and NW-SE. Analyses of morphotectonic features, together with borehole, gravimetric, geoelectric, and structural data, indicate that strike-slip movements were associated with uplift and subsidence of fault blocks. The integration of these data suggests Neogene transtensional tectonics related to early N-S and late E-W compression.
