Abstract Linear dunes are rarely recognized in the geological record. By integrating sedimentological observations with aeromagnetic, magnetic susceptibility and magnetization datasets, we reconstruct the morphology of an Upper Triassic aeolian dune field from the sedimentary architecture of deposits preserved in the Sambaíba Formation, Parnaíba Basin, from northeast Brazil. This dune field was buried by lavas from the central Atlantic magmatic province.
