Short summary
This study describes for the first time morphological aspects of lava flows and structural characteristics caused by lava-sediment interaction in the northwestern Paraná continental flood basalts in the southeast of the South American Plate (Brazil). Early Cretaceous (134 to 132Ma) tholeiitic rocks were emplaced on a large intracratonic Paleozoic sedimentary basin (Paraná Basin), mainly covering dry eolian sandstones (Botucatu Formation).
