Although the Paraná-Etendeka Igneous Province is one of the largest continental flood basalt provinces in the world, there are only a few 40Ar/39Ar ages obtained by the laser step heating method. This problem has raised a number of questions concerning the duration and the peak of volcanic activity, for example. In order to address these issues, this PhD project seeks to advance the understanding of this province by providing new 40Ar/39Ar data from outcrop and borehole samples. The correlation between geochronological ages and a well-defined geochemical stratigraphy is expected to yield important insights into the origin and evolution of this large igneous province.
