ResumoThe Cabo Frio lineament was defined as a continental expression of a ridge offset Formed during the separation of the continents. It coincides with a line o f seismic activity, with several alkalines of Senonian and Paleocene age, and with disruptive structures. Historical and recent earthquakes were located by intensity and instrumental data. The alkaline lineament coincides vith a Senomian-Paleocene plate trajectory obtained through back rotation of the continents along the poles defined by Ladd (1975). Geochronologically the alkalines show a trend of lower ages towards the east. These features indicate a possible existence of a hot spot type mechanism in this area associated with the major mesozoic thermal Ponta Grossa-Mossamedes swell.
