Evolution of cratonic basins
past
Intracratonic basins are large, shallow depressions on ancient stable continental interiors. They accumulate sediments multiple hundreds of million years, punctuated by periods of widespread erosion. Unlike other sedimentary basins, the processes controlling their formation and evolution are poorly understood. In order to better characterise the geological character of such basins, my undergraduate geological mapping project focused on mapping the edge of the Parnaíba Basin, exposed at the surface in the Serra da Capivara National Park, a UNESCO World Heritage site located in Piauí, Brazil. To further explore the evolution of this unique basin, my Masters dissertation characterised the subsidence history of this basin using well and seismic data.
